[Q] Stereo Speakers

Has anyone worked out how to pump the sound out of the front stereo speakers instead of the back one yet?
I've been fiddling with the recently re-appeared Sound Enhancer yet I still cant get any sound coming from the front!

According to the comment on this link
http://www.youtube.com/watch?v=j5W-aAspPA8
they are not actually speakers, just part of the design.
Surely it would be a bit strange to have stereo speakers on the front as well as a speaker on the back?

Funny you should say that now, I just checked the HTC website and found nothing on the specs about it, but I've been reading everywhere else that there are front mounted stereo speakers in pretty much every review, which kind of makes sense for the design....
A final note is also merited regarding the HD7's front-mounted stereo speakers.

And that's just one example. TechRadar, PocketNow and others are all saying the same thing. Ahhhh!

Yeah I have read the same thing.
I dont have the phone ,so cant check it out.
Surely though if they were indeed stereo speakers there would be no need for trickery to get them to work.
I will admit thought the link I posted above is the only place I have read that they are NOT speakers.

Hehe. Fair enough.
Mind you saying about trickery, half of the HTC apps havent been working up until today and even today some of them won't start up. So I'm hoping I've just missed something because the stereo speakers definitely would be a nice touch.

Hi, speakers have magnets, check with something metal...for egz. needle, it's ligth, check first with back speaker if it works and then on the front...

top front grill can lift a pin, bottom front grill the pin stays on my desk,
I cant decide if the pin is sticking to the top grill due to the strength of the magnet in the rear speaker, or if its due to a second speaker in the grill for when the phone is held to the users ear

The needle test is not a good one. We know there is speaker at the top front for normal conversations yet my needle does not stick there at all.

So it has speaker on the back for sure. Do you guys really believe that HTC mounted 3 loud speakers on that device?

I would say there's only the one on the rear and the one for the earpeice.
So far I've noticed the grills tend to collect dust/dirt which is VERY annoying!!!

I posted support question to HTC asking about front speakers from reviews. Got reply yesterday that I might be confusing device as I speak about sorround unit.
I did tell them no HTC HD7.
However today I got a reply saying he looked at the device and other reviews and now knows what I mean. He will investigate.

I believe there has been some confusion regarding the front facing speakers.
I reckon that although they look like speakers that are no more than grills for the earpiece and mic respectively. (which if you think about it makes sense)
I imagine the engineering side of HTC failed to properly communicate this with the press side, and people started assuming they were stereo speakers based on looks alone.
No where in the official specs does it mention front facing speakers.

But the microphone is clearly next to the USB port on the bottom.
I have also saw a video somewhere where someone is reviewing it and points out that the top speaker is a speaker and the bottom "speaker" a microphone and the HTC person corrects him and tells him they're both speakers.

can't owners do a quick test? play some music then cover up firmly each speaker in turn (with thumb maybe) and see if sound gets muffled or low.

there is no speakers at the front of the phone apart from the earpiece above the htc logo

There are definately stereo speakers on the front, one at the top and one at the bottom under the grills. There is also a third speaker on the back, yes three in all!!
I have done extensive sound listening tests to confirm this and it is most noticable if you turn Dolby Mobile on in the Sound Enhancer section which gives a better stereo separation effect. You really have to play music on the handset to hear all three speakers.
The front stereo speakers are not listed in any of the spec I have seen but this is a complete bonus as far as I am concerned. It will even be a huge benefit for sat nav applications guidance voice when they become available.
Well done HTC.

I have only just read this thread and would lik to mention my 2 cents. Yes the specs do not mention the front speakers however, they do mention virtual surround dolby mobile. now anyone would know that virtual surround requires at least 2 speakers ant opposing ends of the device otherwise how could it trick your hearing? I think that though it does not mention "front facing" speakers that there will be indeed 3 speakers or sort.

Speaking of speakers, has anyone found that when linking to Bluetooth A2DP or 3.5mm jack the volume is really low? if I have it on in the car I have to put the volume on about 25 and the stereo on really high too and its quite distorted, doesn't matter which input but my Touch Pro 2 never had this low volume.

That sadly means nothing. Virtual surround could be only available via headphones and they could still advertise it.

Funny I did notice that. However when I first copied my music files some were louder then now. I think Zune is forcing the Volume leveling as all my music files are now of the same loudness.

Guys,
I think you are clutching at straws here.
Cover the rear speaker with your finger and take note of the sound coming from the 'front speakers'.
All you will hear is sound leaking through the case from rear speaker.
If you seriously think that the front speakers are actually speakers, then you must admit to them being the worst speakers in the world!
Also, the different surround modes (dolby etc) are probably intended for use with headphones.
Not speakers, just a bit of artistic license with the design

[Q] [Mod]Use Second Speaker on Xperia Z for Stereo Sound (Like Tablet Z)

Hey Dudes/Dev's
What i want:
I want to Create a Mod which us allow to use the Front Speaker+Side Speaker for Stereo Music
See Attached Pic...
I have tested the Loudness of the Front Speaker and i think the Volume Level is nearly the same to the Side Speaker!(?)
I want to let the Music play over the 2 Speakers like:
Front (Call-)Speaker=Left Audio Channel + Side (Loud-)Speaker=Right Channel=Stereo!?
Click to expand...
Click to collapse
Steps:
-1. Find files which include the Speaker config. Maybe lib-so files?
-2. Find the right way to edit. Maybe i can compare the files between Tablet Z and Xperia Z to find the diffrence?
-#. Edit files to -> Playing Music-> 2 Speaker's active (2 Channels Left-Right),Call Option1-> 1 Speaker active,Call Option2-> 2 Speaker active
-3. Find a Way to make both Speaker's to the same Loudness Level
maybe more...
I really don't know what's needed for this so Please Help!

Good idea

Another excellent idea, though sound when watching movies is allready pretty good, true stereo imaging would be a massive plus.
Good luck with this

Thanks Guys!:fingers-crossed: only a thing of time
To bad that here is still no Dev. Section for things like that. This Thread will go fast to the last pages,and no one will see
BR:angel:

Sounds like a good idea but then again, earpiece is not nearly as powerful as the main speaker and can result in funny stereo audio lol FYI, the stereo speaker positions are a bit weird
In order to achieve in what you want, we need to route all audio playback to play on two channels which is the earpiece and speaker at the same time. We can either do this on a specific configuration file or kernel modifications. I am not sure how to do this as I haven't tried before but it's a start
It's too bad that Sony did not make two speakers positioned like the HTC one... Would of been epic...

wow didnt see you Replied to this thread nice to hear from you...
It's really bad with the Speaker Position... sometimes my right hand mute the Speaker
but back to the idea... it's like you say,the Earpiece is not really Powerful (It's a really Clear Speaker,but no Bass) so you think it's not loud enough for stereo? Maybe we can use it to Support the other speaker (more Virtual Sound or such,i think you know whats good )
The Point is still to find out how we can use the second speaker :crying:
the only idea i have is to find the related files and watch the same files on a Stereo Speaker Tablet to see what we need to change...
when it works we have really found a General Mod for a lot of Devices with low Volume Speaker Devices.

You won't find any related files which will route your speaker and earpiece together.
We need to re-route the audio playback with earpiece and speaker activated at the same time to make both speakers to sound like stereo. If you compare with Tablet Z, you will not find anything because the configurations for that is to route audio playback to both the speaker components and if we do that then it still won't work because we don't have that 2nd speaker.
If we can re-route the speakers into stereo, then we can manually increase the earpiece to make it sound as loud as the main speaker
This is just an idea remember, I don't actually know how we will do this

Any progress on this excellent idea?

speakers

Hi, just got my nexus 6 and noticed that the top speaker is louder than the bottom speaker was just wondering if this was normal also the speakers become distorted on some music but is fine on other.
Wondering what yoir experiance is with the speakers.

My speakers sound perfectly uniform no volume differences between the two. I haven't really experienced any distortion but I suppose it would really depend on what type of music you are playing. In the end these aren't boomspeakers and they are small. But for what they are they still sound pretty good.

yea might have just been the music i was playing because when listening to some youtube videos the speakers seem to sound the same I just recon some of my music isnt proper stereo or something because some things sound uniform some doesnt.

Just restart the phone. This seems to happen to me from time to time.

Anyone experienceing speaker issues?

I have a problem with my speaker sound, while listening to any audio whether it be YouTube, Netflix, Music player etc... After about 6 minutes the sound quality changes it's as if the bottom. Speaker gets lower and the front speaker gets louder if you close the app and then try again it's fine until 6 minutes again. I have already received 2 replacements and all 3 phones have the same problem. Is anyone else experienceing anything like this?

I have the opposite problem, the bottom speaker is too loud and the front facing speaker is too quiet. I have unsuccessfully been trying to find an app to balance them with no luck.

If you have had your device for less than 14 days, I would take it back to the retailer for a replacement. As there is a chance that you were given a faulty unit. Otherwise take it to a Samsung Service Center and let them take a look at it.

You're not the only one. I made a thread about this a while back but nobody here really noticed. It still happens on my latest software update (ARJ1, September security patch). On Samsung Community there's a lot more complaints:
https://us.community.samsung.com/t5...ote9QuestionsandAnswers/page/1/thread-id/1440
Some people tried contacting Samsung but the staff had a hard time detecting it. I got mine overseas in Taiwan and can't readily communicate with them at the moment. I always get a "due to we don't understand your message" reply if I use my phone's feedback option. I did try to email them directly but the reply seemed somewhat generic like "try using safe mode". I haven't done this myself but other users have said it still occurs in safe mode.
The fact that replacements have it lead me to think it's a software bug - the bottoms speaker is supposed to emphasize bass a bit more than the top speaker but it almost sounds like the left and right speaker EQ gets swapped (even though the stereo channel polarity is still constant). When it happens the top speaker becomes bass-heavy and bottom speaker sounds bass-light and treble-heavy. It also seems "worse' in some apps than others. For example I barely notice it in music as only the bass seems to drop on the bottom speaker but on other occasions it sounds like the bottom speaker is sucked down in volume.
Really hoping Android Pie fixes it.

I haven't noticed this issue, but I did post a few days ago regarding sound skipping and corrupting on wired headphones.
I've tracked this down to the EQ not playing well with the UHQ Upscaler. If you have any EQ set other than Normal the sound gets distorted through headphones.
Maybe it's related? I know the UHQ Upscaler is disabled when playing through the speakers but the EQ isn't, do you use anything other than 'Normal' EQ settings?
It has only started on ARJ1 (Oct Security patch level) for me. I've fed it back to Sammy.
Oh, you can download Sound Assistant from the Galaxy Store and that lets you play with the left / right balance.

I didn't try Sound Assistant yet, but I forced the speaker output to mono in the phone's settings, and the problem still occurred. So the problem isn't related to the stereo imagery, but rather how each speaker is tuned regardless. Some have suggested it could be a defect in the amplifier but I think if this were the case the effect would be more permanent. I think it occurs more frequently in the ARJ1 update compared to the update before that. I don't recall it occurring in Samsung Music very often before but now it seems to happen after about 4-5 minutes. I temporarily exited the app (without closing) and played music from Poweramp, stopped, then played music on Samsung Music and it sounded normal again.

Blah - is it just me or has this issue become somewhat more easily replicated, but more inconsistent? I was watching some videos with narration, and it sometimes feels like it pans left and right at the same timepoints when I replay that section.
Also, Horizon Chase sounds pretty awful now. The music volume seems to dip out and the sound effects are too loud.

hi all after 1 week of trying i figure out how to fix the problem simply delete the file with name ((SoundBoosterParam.txt)). in the root/system/vendor/etc
you're done

You need root in order to delete the SoundBoosterParam.txt file, and I'm not comfortable rooting a $1k phone under warranty. I turned off Dolby Atmos and changed sound to mono...EQ is normal. While mono isn't the quality sound I want, this has stopped the issue. A user at https://us.community.samsung.com/t5/...thread-id/1440 though said it didn't fix his.
Like FYL21, I tried emailing Samsung but got the usual "this is another canned robotic answer that doesn't address the issue" response. So I just spent about an hour on the phone with them. After continually trying to explain the issue and being told everything to try that's been tried, I finally spoke to a manager who made note of the links to the issue on their forum. She is escalating this as an issue for the technicians to read the complaints and look into this. Maybe it'll be fixed by the time the Note 10 comes out.

That was me as well in that thread. The thing is the speakers are still tuned differently even if they are in a mono configuration - the bottom one is EQ'd for bass and the top for treble (I'm not sure if this changes if you rotate the phone). I got Android Pie but am still testing out if it happens. Some apps or videos still have brief panning at specific time points, but this might just be related to the equalization and it doesn't seem as long-term as it was before (where you had to restart the app or plug/unplug headphones to fix it). I can live with that but it's annoying when it abruptly dips on the bottom speaker and even worse for calling.

you guys should think of this phone as a sound bar.
in that type of configuration, its one device generating sound that appears as stereo even though there is 1 device and not 2 .( or more)
the position and tuning of the speakers within that bar is tuned so that it feels like stereo/multichannel.
so in the same way is the phone tuned that way. plus if you think of it, you hold your phone 90 %of the time upright. the speakers on that position are not left to right but top and bottom...
so again don't look at the position of the speakers on the phone to deduce which is the left or right speakers but as how the devixe as a whole is reproducing the feel of stereo without an array of speakers like on home cinemas or in your car.
think of it, the space between the speakers is so narrow that youd have to be a small mouse to be able to enjoy real left and right channel audio from the speakers in landscape...
anyways this has nothing to do with the audio fading out but more towards our expectation of multichannel audio and how the phone reproduces it.

Does the top and bottom speaker sound different to you?

Hello! I noticed the bottom speaker sounds a bit louder than the top one, specially with higher frequencies. Is this specific to my unit or is this due do a difference between the speakers in this phone? Anyone can relate?

Be aware that stereo signals might affect your perception of them. Try turning on mono audio in accessibility settings.
As far as physical differences go, they are indeed different in size. You can see it here:
?t=6m1s

After 2 weeks of owning this phone, I just noticed it now. Bottom speaker does sound louder than a top speaker. So disappointed to find out that both speakers aren't equal I bought this phone mainly for front stereo speakers.

I think Top speaker is an earphone doubling as speaker. Bottom speaker is a dedicated speaker.

I noticed something strange. After turned off the phone for a few minutes and then turn it back on, now both speakers sound balanced just like when i just got the phone and had not noticed this issue until now. Please try turning off the phone, not restart.

Software problem
Not hardware
Speakers hardware are great

I hope Asus releases updates that allows user to adjust the balance of stereo. I think it's also the stereo frequencies in each content. some music, video, and games are noticeably louder on bottom speaker, and some are louder on top speaker.

I just turn on mono audio when the speakers are in use. The stereo separation doesn't work well enough for me, and it just sounds fuller.

I'm also aware that the phone has 2 vibration motors, but I noticed the vibration is much stronger at the bottom, anyone noticed this?

I can definitely relate to this. But overall, I'm very satisfied with the quality of the speakers.

Do y'all have your bottom speaker blown out or distorted?

guys Ive owned several stereo phones before and almost all of them sound differently, you just need to turn on Mono audio as other's have mentioned too.
this phone has great speakers, reminds me of my HTC 820 boomsound speaker which were pretty loud back in the day, but this is loud and clear!

Bottom Speaker sounds louder
@Mike845 Thanks for posting this issue as I am also facing the same issue. I am skeptical as this being a hardware issue because I saw jerryrigeverything's video on YouTube and top speaker is indeed smaller than the bottom one.
I want to know that are the top bottom speaker should be of same intensity or is there a problem with my unit. Also if buttom speakers are loud than top one and there is no issue then I am very angry with Asus as one of the reason for buying this phone was dual front firing stereo speakers.
For all the other folks, I request you to check your device for this issue(balance) using this link youtu.be/2ZrWHtvSog4 . Here you'll get perfect idea if speakers are balanced or not.
Please help me so that I know that if this is an issue.

Yes at high volume bottom speaker does sound distorted.

Tweak for balancing speaker audio
Okay, first of all switch off and reboot (not restart) your phone.
Then go to AudioWizard, switch to normal mode if not already then don't exceed the volume beyond 10 notch. Now check, speakers would be balanced and clear.
It becomes unbalanced only after 10 notches where only bottom speakers volume gets increased and not top. Also beyond 10 there could be distortion in bottom speaker.
Hope it helps.

Also in Asus ROG Phone III
It is on Asus Rog Phone 3 too, very disappointed. With black crush issue.

I don't know how YouTubers are saying that Rog has got the best display ever, paid reviews probably. These YouTubers are taking people for granted.
Asus's image processing is just ****, black crush, red tint and what not.
I don't know why I went with this when OnePlus 7 pro was equally priced. Regretting my decision.
