Speaker not fully duplex?

Hi,
I have a very weird problem with my Tytn II, which I bought little over a week now.
People I was talking to complained they didn't hear me very good, the sound appeared to drop. It occured to me that it was happening when I used the speaker (handsfree) of the phone.
I did some testing, and this is what happens:
I (with the Tytn II) call person X, and when I and person X are talking together, person X cannot hear me, the sound on his side simply fades to nothing, until 1 of us keeps quiet. The same happens when for example sound from my car is picked up by the phone, thus resulting in the device not being usable in the car, since there's always some noise. I however on my side keep hearing person X, it's person X that doesn't hear me.
It happens with 2 sim cards, everyone I call, did a hard reset, HTC support doesn't know the problem...
I'm puzzled. Can anyone suggest anything? Or is it faulty?
Thanks

no, mine does the same thing. I got it a few days ago and when i used speaker while driving, i could hear the other person perfect, but they cant seem to hear me. It feels like half duplex. i hope this is fixable

Damn, it seems widespread then...?
Anyone who can test it?

maybe it has to do with whatever noise cancelling algorithm is in effect is mucking everything up

Meaning that every single device would have this, and thus mine not being faulty?

I had the same problem but remembered that there was an automatic sound function which turns down the volume when talking is too hard and turns it up when to soft. Its called microphone agc and you can find it under system configuration. Now that it's turned off my dutch htc tytn II works fine in handsfree mode. Hoop this helps you also

It's already turned off :-( .
However, I just called with HTC, and they said it's because of the mic and the speaker being too close to each other, and thus it compensates.
They say every model has it however, they did a test today and the result was that it was a feature, not a bug...
Anyone here who does not have it on his device?

I have this problem all the time, both on speaker and just using the phone to my ear as normal.
People complain I am very quiet or that the sound is choppy and I sound like a robot
I used to have this problem on the O2 XDA IIs a few years ago.

Anyone else have it too? I'd like to know asap if this device is faulty, or if it's normal?
Sometimes, it seems that when I'm holding it to my ear, the sound seem to drop on the other side too...

I have exactly the same problem. People have trouble hearing me with loudspeaker switched on. Without speaker they can hear me perfectly.

I have the same problem too. Just try to disable the Microphone AGC thing and it fixes the problem. Thanks downnootje.

I have teh same problem , but I tried something and it is improved the Operation , try to minimize the Speaker volume to the minimum level and then it improes a little and it works for me ; not all the time but that is what we can do at the moment

I'm convinced now that it's a mojor problem.
Mine even got worse: since yesterday, it's happening without handsfree too, people can't almost hear me when I just hold it to my ear...
Is this a phone still, or can't it be used as such?

try enableing Microphone AGC thing, restart phone, and disable it

Me too. Juz got my set 2 days back. The other party hears my voice intermittently chop-off...
I have faced the similar problem on a particular China-made TV phone too. Tested two other units of the same model still the same. It seems to me the phone design issue, as after I changed to another model of China-made TV phone, the problem solved.
Sigh! Already got this expensive phone, think have to bear with this feature then if it is really cannot be resolved by new ROM.

same problem
i have the same problem...with my 8525 when I was on the train or in a similar noisy situation i never had any trouble with people hearing me on the other end...with the tilt i can't even carry on a conversation on the train...i called tech support and they told me to swap it out for a new one.

I've tried that and it doesn't help! Quite sad about it. I need to use speaker handsfree especially during driving.... Don't really like to hook-up the headset or BT headset... too messy for wired headset and too tedius (charging) for BT headset...

Now that I know its half duplex it works pretty well in the car - I just wait for the other person to stop talking
Surur

I will be sending mine to HTC for a planned hardware fix as they agreed there is a defect that affects all kaiser and tilts, but NOT the MDA VARIO III. this is a known issue and is hardware related. Good news for those who havent purchased one yet. I will sell mine on ebay if they dont asign me a RA soon. I rather have the MDA VARIO III as it has 2 cams.

(doesnt your HTC TYTN2 has 2 camera's?)
Same problem here. Hope for a sollution soon!
Will call HTC too soon, so theyll have more complaints about this defect.

Microphone broke

I have bin on a holiday for a week, using my X1 in the plane as a music player only. After I came back yesterday and I tried to call someone the person could not hear me.
I tried a soft reset, still didn't work. Tried to call an other mobile of mine, still no sound. If I blow very hard in the microphone hole I hear something on the other line.
The only thing I did before leaving on my holiday was uninstalling SRS WOW because I could not change the volume in media player. I tried installing it now but that didn't help.
Also If I try to call handsfree using my bluetooth carkit it does work, but if I try to record a movie with my mobile it does record sound...
Has this something to do with the software or the hardware of the phone? Any suggestions are welcome, thank you.

Sounds like it's software. While you're in call, press the up button on the top right of the phone to turn the volume up.
(I just got my X1 and it's the first thing I could think of)

No that doesn't work, and the strange thing is that my TomTom doesn't give me any sound anymore. And its settings are all ok.
When I turn on my phone then it shows the headset icon for like 2 seconds and then it dissapears because of the some other icon replaces it.

Earpiece and Speakerphone super low after using bluetooth handsfree.

Hi everybody. I have the t mobile moto x 32gb on ATT. Works great ..the best phone no questions. I have an older car with aftermarket JVC unit with bluetooth capabilities inluding A2DP(which works great by the way) but the microphone of the JVC is not good so I don't use it for phone calls. I had that issue before where after the phone being connected to the car and disconnected (when I leave the car) the sound is super low it shows max but it is not(the moto x has great crisp and loud sound both on the earpiece and the speaker), so I have to restart the phone and this will fix my issue..but since I am not using it much I was ok with it...Now I have a 2010 Prius with blueetooth handsfree calling but no A2DP(that is ok with me I can use the AUX). The microphone on the Prius is great people are saying they hear me great and so do I. But now I am facing that issue again..
Is anyone familiar with that ? It is really annoying that I leave the car where I was in a conversation with great sound I lock my car and walk on a busy street and cant here what people are saying no matter if I am using the speakerphone or the earpiece..I have to tell them that will call them back in a minute after I restart my phone.
PLEASE HELP !
THANKS

Anything ?

Try persist+ from play?

Bluetooth volumes have been haunted ever since 4.4. Hell... plugging in the charger when I am on my vehicle's bluetooth changes the volume.
Hoping this finally get this fixed in 4.4.3, but until then, I have found a number of tricks.
1.) There is a sweet spot on the volume scale (around 70%) that is best to leave it at.
2.) I haven't had to restart my phone... usually just cycling BT off and on again restores original volume. Sometimes even starting/stopping media playback fixes it.

I can confirm to have the same problem. Hope it'll be solved in next updates.

[Q] Sound gaps while BT streaming to car audio.

Hi, I Have strange problem with my brand new Xperia Z3 Compact. I streams my music from Z3C to my Pioneer MVH-X360BT car audio. Every few minutes there is a gap in stream that lasts for maybe half a second. That's very annoying! Music is still playing during this gap but I can't hear it. I had similar problem with Xperia Z1 but I thought it was some problem in old Android and some bug in BT driver. Then I've had iPhone 5s and it worked like a charm! No gaps, no problems with BT. Now I've returned to Android and I'm starting to regret this :/
I've checked everything I could. I've turned on BT visibility, turned off Wi-Fi, checked if no notifications couse this. I've even flash clean stock firmware (originally phone came with branded firmware). Nothing. I've tested many players (Walkman, Power Amp, Player Pro, Double Twist etc). Nothing. I though that maybe problem is in my SD card (I store my music on external card), but: 1) it's very fast card 2) copying music to internal storage didn't change anything. Sound still has gaps. I don't now what to do I'm sure that my car audio is ok (iPhone works), today I've tested SGS5 with it and it worked well too. Problem is only with Xperia family (reminder: same problem on Xperia Z and Xperia Z3 Compact).
Any clues? I hate changing my phone again and I love battery life on Z3C (main reason I left iPhone).
Please help!

I have BT headphones and I am not experiencing those issues at all. Could it be that your phone goes into some kind of sleep mode and then wakes up again? Try with some app that keeps your phone constanly awake/screen on. Does the issue persist? Can you try out any other BT audio devices and report if the same problem exists?

Huh, I've turned off the 'Queue data in background' (I have polish locale and I don't know how this option is in english so I translated it literally) option in power management settings. Nothing has changed Also nothing has changed while I was driving car with Google Maps navigation (or Waze) turned on. Still gaps were present.
Unfortunately I don't have any other device that I could test my phone with Only other phones (and all phones works great).
I think I have to change Z3C to another phone, maybe SGS5 (but I don't like Samsung...)
Ehh, tough one

Hi there, I'm facing the EXACT same problem with a few minor differences in the setup:
I'm connected via cable to a philips CEM210. This so called "gap" usually happens when I skip a track(or when the next track comes on automatically).
I have recently purchased the kinivo btc455 and will let you know tomorrow if the issue persists on the BT device.
I actually think 2mal might be on to something here I use stamina mode regularly and I have rooted my device and change tracks via the volume keys.
So the issue might be the phone wakes up periodically (skip track? check notification queue?)

I have all power safe options turned off. Notification queue is empty. I have this problem only via BT. When listening with phone connected to radio by USB, everything is ok.

Try this app while you listen to music over BT : https://play.google.com/store/apps/details?id=com.synetics.stay.alive
Still gaps?
Also I have Viper4android installed, dont think this would make a difference since it also worked before but its worth a try.
Get the apk from here and follow the instructions : http://forum.xda-developers.com/showthread.php?t=2191223
I assume your device is rooted as it only works on such.

Speaking of weird bluetooth bugs, my music has been playing in fast-forward occasionally (cm12). I have no idea why this happens or how to fix it, so if anyone has any ideas I'd greatly appreciate it.

Stay Alive didn't help. There are still gaps once for a audio track.
My device isn't rooted so Viper is not an option :/
Thank you, though

Hmm , last idea , try turning the timeout for visibility option in the bluetooth menu (in the right corner on the bottom when bt is turned on) to no timeout.

That was the first thing I did. No effect, of course.
Sad but true - I have to get a new phone. And this time no Sony

Jeah too bad i could not help, what you could try is go to a store and ask them whether you could try out some BT headphones, with the pretext of buying them ofc . If the issue is still present then it may be hardware related and an exchange unit could work just fine. Otherwise it points to some incompatibility issue that could maybe fixed somehow but not by me and my current expertise . Especially since i am not experiencing the same. Wish you the best and good luck !

I use a Bluetooth headset (mw600). Started with a nokia n900 and it had frequent gaps, probably due to wifi/interference. With the Z3C started with no gaps but now get few most likely when it leaves any wifi connection (hotspots).
Since you have tried all options on the phone side, it seems to be an issue with the particular car stereo. How about you reset the stereo by removing all power sources to it then pair the phone as a fresh new device and check if issue continues?

I have a similar issue. It seems like a head unit problem for me. Many problems there are with Pioneerer Head Units. Please don't buy this brand...

Have same problem with my Z3 and pioneer car sound.... No issues when i used samsung devices... Now i have a Z3 and the sound fails all the time....
I have 2 headsets bluetooth and i dont have any trouble....
The problem is between sony devices and pioneer!!!
Help!!!

This is not just between Sony and Pioneer. I have a Cardo Scala G9 BT headset for motorcycles, and never had a problem with my Nokia 808 for music streaming, nor my Nokia X2 DS (strictly used for GPS, no SIM).
Now that I bought my Z3C, I have this random gaps of silence while streaming music. Extremely annoying. Even after rebooting the phone, no resolution. Thought maybe there are some bugs with 5.1.1, so I went ahead and updated the firmware on my G9 from 1.6 to 2.1. Still same issue.
Another issue I found with the Z3C: When music streaming is playing, and I get a text message or a new email, the music volume lowers, but no notification sound comes through, before the music volume resumes. On my other phones, when I get a text message, the music volume goes down, and I hear the audio for new text, email, or whatever.
It is extremely annoying. Anybody know how to resolve first and second problem I listed?

Not a Sony issue. Had this with an lg g3 on a kenwood car stereo and the same with the z3c. Seems to be an android issue, as it didn't happen with ios. I am not 100% sure, but I think it only started with lollipop, because I had an htc one m7 before the lg and I don't remember ever having this before...

Yeah, I am inclined to agree with you.
With my Acura, the music has zero gaps. But when I am on a hands free call, I get the gaps! So it must be something buggy with how Android handles one of the BT channels. It is extremely annoying. And on the hands free calls, when the gap happens, my telephony audio goes to the phone. And when I try to switch it to BT mode, nothing, until the gap ends. Then I can switch back to BT mode. This is extremely frustrating.

Bump. I've been having this problem for months. I had it in KitKat too and it happens with any Bluetooth device. It always happens in specific parts in my route (place I go to often), even though I may have never connected to WiFi there or WiFi is off. Could it have something to do with GPS activity?

Any solution for this strange problem?
xperts help please!!!

Hello everyone!
I also have exact same problem with my Z3C and... Sony's MEX-N5100BT, there's a couple miliseconds gap while the music is playing. The best part is that while I'm talking through the radio's built-in BT Phone, the audio never has this gap... or I haven't heard that since I'm using this radio.
But you know what? This happens so rarely that I just ignored it and got used to it and I recommend you to do the same

Audio playback skips when waking screen, using wired headphones

Hi!
I've been using a bluetooth headset and speakers since I got my XPX, but I recently started using a wired headset at work because the battery in the bluetooth one didn't last all day. I've noticed that whenever I wake the screen, either by double-tapping or using the power button, the playback skips forward by one or two seconds. This happens no matter what audio player I use (I've checked Spotify, Poweramp and Pocket Casts) and only when using a wired headset. Bluetooth and phone speakers are unaffected.
I haven't had the chance to try other headsets with this phone, but this headset didn't cause this to happen on my old phone (Z3C). Since it only happens when I wake the screen, I kind of doubt it's the headset anyway.
Does anyone know what could be causing this and how to fix it?

Sorry to bump my old thread, but I 'd forgot I posted it earlier. I noticed the problem again today and was about to post about the problem again.
Does anyone know of a solution to this problem?
