Echo issue on calls - Githubissues

vchiotelis commented 10 years ago

From the first rom 5.0 I'm facing issue with the echo when I perform calls. The partner from the other side hears his echo. Εverything works perfect with headphones. Also I can provide you logcat if need it.

I can confirm this issue.

I have manage to get a new logcat from my phone with the latest boot image 5.0.3b. I have upload the log at the below link.

In the log i have perform two phonecalls, one without headset and one with headset.

Unfortunately a logcat will not help in this case as i am simply not able to reproduce this problem.

I already did multiple phone calls and so far nobody complained (i even phoned myself a few times and there was no echo).

Did this also happen on my 4.4.4 Release (http://www.blinkenlights.ch/ccms/android/yuga.html) or/and what ROM were you running before my 5.0 build? (where i assume that the issue did not exist?)

vchiotelis commented 10 years ago

No this doesn't happen on official rom 4.4.4 .283. I have also test it. I have roll back the phone on official kitkat and everithing works ok no echo. Later on I will try your 4.4.4 kitkat release and I will lets you know if I have any issue.

I have also flash your rom Android 4.4 for Sony Xperia Z (YUGA) and I have the same issue with the echo. I flash back the official kitkat rom 4.4.4 283. I have perform some tests with the official Sony rom and there is no echo on calls. Also I have check the audio_policy.confg and I notes that they have perform many changes there. Do you believe that if we apply the same change at you rom audio_policy.confg may fix the issue?

I'm investigating this issue and later on I will flash again your Android 5 rom 5.0.3 in order to perform some tests. First I will try to replace audio_policy.conf and audio_effects.conf with the conf files from Sony official kitkat rom. If this not works I will try to add on Android 5 audio_effects.conf the below line for noise suppression.

pre_processing { voice_communication { aec {} ns {} } }

I will lets you know with the results of all above tests.

What happens if you do:

adb shell
setprop persist.audio.fluence.voicecall true
setprop persist.audio.dualmic.config endfire       
reboot

? Does it make any difference?

vchiotelis commented 9 years ago

Sorry I haven't try anything. I will try today and I will post the results.

vchiotelis commented 9 years ago

I flash the latest rom and seems that everything its ok, no echo. I don't know the changes but now works ok.
