[Q] Bluetooth Audio Distortion - Sprint HTC One (M7)

I'm having an issue with distorted audio when connecting with my phone. I'm using a JVC KD-R730BT headunit if that matters. I read that some other people are having issues with bluetooth audio distortion (mainly in the higher frequencies), but no one seems to have a fix for this. Does anyone have a clue what I should do about this? I've been using an aux cable but I don't like it since I can't use headunit controls.

I remember older versions of bluetooth were so slow that you could only transmit low quality/pretty compressed audio over it. I'm not sure how much it's improved over the years, but this is certainly a possibility of your problem.
You could also try turning down the volume some on the phone. I haven't had a problem on my One distorting with max volume through aux, but I did with previous phones and mp3 players. Basically, max volume can cause the levels to peak and audio to clip - chop off the ends of the wave form. In other words, distort. See if turning the phone volume down some helps prevent this. Can't say it does as I don't use BT that often.

Turning it to about 11/15 helps a liiiittle, but it's mostly because then my volume doesn't come very loudly through the headunit so I can't hear the distortion that much.
Also, my EVO 3D and EVO LTE had no problems with this same headunit. Just this phone. I also got a replacement One since my original had light bleed and screen issues. The new and old ones both distort.

The bitpool rate is too low. I assume you're using a sense rom because that's where the problem is present. Unfortunately there is nothing you can do. HTC needs to raise the bitpool through a software update. Not even devs can do this because its closed source I believe.
AOSP roms should not have this problem.
I don't understand why they set it low in the first place. It makes no performance difference where its set from what I know. Its merely a limit raise in the code.
I explored this issue extensively on my e4gt because it had the same issue. I can link you to threads with more info later if you desire.
Rumor is that it may be fixed in the 4.2.2 update but I haven't seen it officially listed. If its there we won't know till we try it. And no telling when that'll be.

Damn HTC. That's really frustrating. Oh well. Here's hoping for the 4.2.2 update.

If this got fixed with 4.2.2 it would be amazing. It's annoying having to use the aux jack in my car with this phone when all the other phones I've had could just stream music over Bluetooth.

I wouldn't count on a fix being there though. Few users stream Bluetooth audio, of those few, only a small number notice the quality difference, and of those, only a minute number care enoungh to mention and complain about it here. So if it's on HTC's radar, it'd be nothing short of miraculous.
I'm hoping for the best with you guys though.

i used volume+ on my galaxy nexus which had the worst volume output i have ever seen, worked like a charm though and should work similarly for the note....
I use Vodoo Louder for headphones, although I am disappointed as all hell that upgrading to ICS only gives me up to +3db boost versu the 10.5db boost I had on GB. I asked Supercurio via email, twitter, and xda, and I haven't been given a response...not sure why I support him anymore to be honest.
I now pretty much use Volume+ for BT, unit speaker, and headphones.

My Take On The Nexus 4

As someone who has tried (and failed) to switch from iOS to Android in the past, I feel I should share this with other who maybe have the same problem.
I have tried some many android devices, HTC, Galaxy S, S2 then S3. Galaxy Note, you name it I've gave it a go.
Problem I always had was that it was too laggy or had too many things missing for me that I loved about iOS
I have once again taken the plunge with the Nexus 4.
I LOVE this phone. LOVE. It is everything a phone should be, to a point. It's the best android phone i've ever owned. I hate the look of touchwiz, never a massive fan of sense, the sheer beauty of the "people" app, should be enough to tell you that google has ARRIVED.
My only bug bears are the obvious lack of storage, which i'm actually doing suprisngly well with, like I have an N7 which I watch films / tv shows on, so the N4 is basically for music, along with spotify it's working like a dream (also have google play with 16,000 songs, which is working well, although download speeds are awful)
The other biggy, and this is the one is the battery life, I've tried franco kernel, cm10, stock kernel, etc etc. There's no two ways about it, with the screen turned on and using 3G it EATS the battery and that saddens me a lot. I'm lucky that I can charge it at work, but lordy lordy lord does it eat a lot. It's a shame, I'm hoping in the future they'll be a fix for this, I mean it's not a show stopper, but it's more annoying than anything else, seeing the battery go down as you use it for browsing and listening to music etc
Other than that, I think I've finally done it, I've finally broken the iOS spell and made the move. I'm delighted, the phone is lovely to look at, lovely to hold and use (and actually works unlike my f*cking iphone which dropped calls left right and centre)
I'm chuffed
Congrats man. It's pretty normal for a new phone to have horrible battery life at first, but then to get a big improvement with software updates.
Suprised that Franco's kernel isn't helping you though.

try faux kernel. undervolt by -100mv on all frequencies, lower your max frequency to 1134, and change governor to intellidemand. you should see better battery life then:thumbup:

faux kernel app is a paid app on the play store. i use trickster mod to change frequency/governor, and system tuner to change voltages. both are free from the play store. just remember to hit the"apply" button if you use trickster mod. also use one of faux's latest beta kernels. I think its up to 003b10

ahh thanks man, appreciate the help
I cant help but think though, that phone manufacturers should stop worrying about siz and weight and just stick a slightly better battery in. I mean a couple off mm and a few grams is hardly gonna put people off buying a phone.
I know for me the first thing i look at is "Battery Life" not size and weight.
I mean look at the iphone 5, it's too ****ing thin, make it the same size as 4s and stick a bigger battery in ffs
Definitely I know for myself that I'm happy with anything below 1.5cm which we know would give a lot more battery life,shame we are stuck with manufacturer's going for thinner phones and the only company to buck the trend is Motorola however their phones currently suck .
Battery life is improving for me I have narrowed it down to the radio, it seems mobile data destroys it much more than ant other phone I have used...WiFi performance is amazing and idle well I can say its the best. This was on the matr1x 4.0 kernel, not stock however.
Not sure why mobile data kills this device but WiFi efficiency is through the roof at least

hi
have installed faux kernel changed the first couple in trickster but am unsure of how and what to change voltage wise in system tuner ???
any advice ?
Battery life is definitely a problem when using a phone with mobile data on. That's Google's mistake with android 4.2 and hopefully be fixed on 4.2.2.
Also congrats on moving to Android. I also moved from iPhone to android. To nexus s to be exact. The experience wasn't lag free but it did what I needed to and I loved the customization that android brought. Since then, been using android, but only nexus devices as I love pure android look

you realize that the iPhone's battery is about 1400 mAh right? the secret here is an efficient yet limited software.
that's not to say that the 2100 mAh is not big enough for an Android device. it should do just as good if not better than the S3, which has a similar sized battery. something certainly is not working as intended. some say a buggy radio, others speak of the 4.2 and hardware not optimized. whatever it is, i am hopeful that a software update will take care of it.
i generally agree with the OP, i don't see myself using skinned Android anymore. stock android>IOS>skinned android.
Vanilla android >jail broken iOS>90" TV's

open system tuner, press the voltage button, the first voltage (384) should be 900mv. press the -12.5mv a few times until that first one says 800mv, now they're all lowered by 100 you can go further if you want, some chips can handle -150 no problem. but in my experience 100 is pretty safe and enough to notice a difference in battery

Android is already better than iOS in terms of users anyway, I would like to just pick at the part of Jobs making the touchscreen...he didnt it was infact HTC that made the first capacitive touchscreen device, Apple just put together all the same hardware 5 years later and marketed the crap out of it which is great its typical apple and now we have an amazing market where Android exists and these high end smartphones are popular and back in the market .
That's apple all over though really isnt it
I mean archos brought out an Mp3 player with video about 3 years before apple did it on the ipod, apple then claimed they invented that, along with the wheel, dinosaurs, and the earth
If you guys are worried about the battery I highly recommend an external battery pack. I know they look sorta gimmicky like that stocking stuffer present you get and never use but there are some sleek looking ones that match the beauty of the nexus 4 and are easy to use. Its sorta like carrying another phone around in terms of weight/size.

The op said he has access to a charger so what is the problem? It is not like we are in the woods.
You are using a personal computer. If you sit down and listen to music and have the screen on how long do you expect it to last?
I also listen to podcasts bit I know of I do this I will not get an entire day.
When I use the phone normally I get great battery life. Just go into your apps in the panel and look under running. Use titanium backup to freezing what you don't need.
Good luck..

[Q] Lag Spikes

Since getting my HTC One I can't help but notice it displays lag spikes in places where the hardware alone simply shouldn't lag. A few examples can be found in Angry Birds (play it alongside a recent iPhone or the Galaxy S3 and there's very visible differences) and Youtube (very surprising considering its multimedia prowess! Tends to get small spikes of lag in the first few minutes of a video, fast music videos tend to easily point this one out).
These spikes were also visible on my HTC One X as well but can't be found on The GSIII so I don't want to go and blame android here but is there something that can be done to remove them? I know it's all very minor but when you've seen it you can't un-see it! I had an idea that it may be HTC's processor management not ramping up the power quickly enough for apps (but i'm no expert!)?
Any help in finding ways to diminish these would be greatly appreciated!
Do you have power saver on? That may be why. I haven't noticed these lag spikes at all.

Nope Power Saver is off.
These bits of lag are small, but they're definitely there, if anyone has the Impossible Game that's an incredibly good example of what i'm talking about.

Old games do not work well on this phone

For example I tried playing the original angry birds and it is extremely choppy. It seems like a bunch of the old 2d iOS ported games like angry birds, cut the rope ect don't run that well on this phone. Does anyone else experience the same choppiness in this game? Is it something to do with optimization or is it a hardware issue with the One? Newer 3d games seem to run fine. I hope its not just my phone.
Strange. I just installed it and played the first level and found it to be extremely fast and responsive. Do you have power save mode on?

I don't have power save mode on, I've been trying to diagnose the problem for the last little while and I can't figure out what it is. The game runs fine for the most part it is just a tiny bit jerky, especially when scrolling the background.
Same here, playing games I played on my S3 on my One are quite laggy. Maybe game developers have to add support for our phone?
I found this old post about the HTC One X, perhaps the same issue applies to the One and can be corrected with the same solution?

My phone is not rooted so unfortunately I cannot test it right now.

Another solution, once again requires a rooted device is to install any CPU app like kernel tuner, SetCPU, Trickster Mod, etc. Change the Governor from on-demand to msm-dcvs. In kernel tuner you can a little further enhancement by ticking the box next to link all cores. This will also tax your battery more but a lot less than that in article you linked to.
Both the titles you mentioned run without a hitch, very smooth. Anyone else want to chime in?
Sent from my HTC One using xda premium
Didn't want to start a new thread on same topic.
I've experienced the same issues on my One. In Nimble Quest for example, you can look at the background as it scrolls and every few seconds there's a hitch/slowdown, then the game speeds up again. It can be subtle and perhaps not everyone notices it. Another game that exhibits this, is Canabalt. It's actually more severe in Canabalt.
I have Power Save disabled and this issue still persists. I am not sure what the culprit would be, and I hope we don't have to rely on the developer to resolve the issue. I feel it's something on the phone's side, (perhaps it's throttling down)? I tested the same 2 games on an S4 and the issue was not present.
I am on 1.29.1540.3.

[POLL] Nexus 6 Speaker Quality Issues (Crackling/Popping)

I would like to gauge how many people have had problems with their Nexus 6 speakers. Many have reported a crackling from either speaker at certain instances (myself included). One easy way to test this for yourself is to play the stock ringtone "Ganymede" at full volume and you should be able to tell if there are any issues. It is also evident that my top speaker crackles at various time throughout a call. Basically I'm trying to figure out if all of these devices are like this or if I'm being picky (I've already done an RMA and my replacement device has the same issue). Here is a good demonstration of what I'm talking about: https://www.youtube.com/watch?v=4dcElCL9u3w
My speakers sound just fine at full volume playing Ganymede. I'm not running stock though. Rooted and running 1/20/2015 Chroma ROM, Franco #9 kernel with vomer tweaks/ quad conservative.

I seem to get some popping and crackling at full volume, depending on content. Also, the stereo balance seems off, the speaker at the top of the phone sounds louder.

I guess I've just chalked the issue up to hardware. It happens on stock for both the original and replacement device, as well as CleanROM with Franco kernel. Does Chroma have any audio changes that you know of? I'm not too familiar with Vomer tweaks either. Maybe I'll try another ROM.
Audio FX is all I know. Check out the log. Great ROM, awesome developer and a good community in the forum.
