[Blackview 9800 pro / MTK P70] AOSP 11.0 v303 feedback/echo on phone call audio #1783

[Blackview 9800 pro / MTK P70] AOSP 11.0 v303 feedback/echo on phone call audio #1783

Comments

Half a second delayed echo on any phone calls. Echo is slightly noticeable when using handset to the ear, quite noticeable on Bluetooth headsets or car Bluetooth sets, and extremely loud mic feedback squeal if calls are switched to speaker phone on the handset. I suspect the top mic on the phone is turned on and is basically listening and replaying ( echoing) what is been said into the bottom mic.

The text was updated successfully, but these errors were encountered:

Actually v303 is my first experience with Phh roms directly, before I was using Havoc 3.12 GSI.
Havoc had a slight delay or echo on bluetooth headset/ car sets, but the phones ear piece and the phones speaker phone worked normally with no echo or loud feedback noise.

I’m having the same problem on a Cubot King Kong Mini 2 (MT6761), also on v303.

Stock ROM (v10, kernel 4.9.190+) doesn’t have any audio issues, nor does LineageOS 17 or 18.1, so this seems local to AOSP.

I installed v301 (arm32_binder64-ab-gapps) and did a factory reset. While setting this up a couple of apps where automatically updated, but I guess this should be as close to a clean 301 as it could be.

Now there’s a different problem: when sending calls there’s no audio going either way. When receiving calls everything seems to work OK.

I’ll try another versions and report. Would it be enough to just flash the newer version on top of what’s there, so I don’t lose my settings after every flash, or you’d prefer a factory reset between tests?

I tried other versions, just flashing on top of each other without factory resets:

• 302 on top of 301: same problem as v301. I think the mic is never activated.
• 303 on top of 302: back to the original problem: audio works both ways but a terrible echo problem.
• 304 on top of 303: same problem as 303.

I have this same audio problem in the call on my ulefone armor 3W (MTK 6771 Hélio P70). I tested version 302, with no audio on the outgoing call, only on the normal incoming call. in versions 303 and 304 the audio works but with a very loud feedback from the speakers, as if it were an echo, as if placing the microphone in front of the speaker, even with the speakerphone turned off, only with the headset it gives this echo of feedback. on Android 10 it doesn’t happen, only with Android 11

problem solved for me with this latest update in version 305. call audio working perfectly. congratulations to Phh

v305 partially solves this problem on MT6761: calls received/sent work OK when using the phone, but the echo problem persists when using a bluetooth headset/car connection.

I didn’t include that bluetooth test with v301~304, but I believe this problem is also present in v222

I also have this issue on all a11 for mtk p70. Present in 305. Is it worth updating to 306? Or has nothing changed with regard to this?

Still there in v306 (Unihertz Atom L, MTK P60) — on regular phone speaker and on bluetooth as well, in my case.

Ok so the latest v306 completely solves the loud feedback on regular speaker phone use. Unfortunately the Bluetooth headsets and car sets are still echoing your speech back through the Bluetooth speakers or car speakers. The delay between speaking and hearing it replay is about 0.5 second

Echo still present on v308 for Bluetooth headsets and vehicle/ car sets

I noticed that in /vendor/audio_policy_configuration.xml and /vendor/audio_policy_configuration_bluetooth_legacy_hal.xml, AUDIO_DEVICE_IN_BLUETOOTH_SCO_HEADSET is set to AUDIO_CHANNEL_OUT_STEREO, which seems wrong. I tried changing the value by overwriting the files through Magisk but it didn’t have an effect.

Edit: #1321 Seems to do the trick for me (Cubot KingKong Mini2)

How to fix an audio echo problem with bluetooth headphones on Windows 10

I recently got shipped a new bluetooth headset for work. The headset in question was the MPOW HC5 headset. They are very comfortable and have good audio quality but when they first arrived there was a problem. The audio had a persistent echo.

The echo was isolated to the headset as there was no echo when the audio was coming through the laptop speakers.

The echo was also isolated to Windows 10 as there was no echo when the headset was plugged into an Android device.

At first I thought the problem was caused by the Windows 10 audio enhancements settings. These settings include an option for echo. However in this instance this was not the cause of the problem.

To rule out Windows 10 audio enhancements as the cause of the problem do the following:

Control Panel > Hardware and Sound > Sound > Left click on Speakers (or another output device of your choosing) > Properties > Enhancements > Check “Disable all sound effects”.

In this particular case the echo problem for my headset was that playback was happening twice for the same device albeit slightly out of sync thus creating an echo. The problem was identifiable as when I traversed to the option path below I could see that the headset was registered with the OS twice under two slightly different names.

Control Panel > Hardware and Sound > Sound > Playback

I tested playback for both device names, by right clicking the device and clicking test, and found that one of the devices had a audio glitch. When this instance of the device was disabled the headphones worked without any echo.

Moto G эхо от блютуз гарнитуры.

Подключил блютуз гарнитуру — все работает нормально, но собеседник слышит свое эхо при разговоре, на моей стороне все отлично — без артефактов.
Подскажите, как побороть данную проблему.
Что надо сделать?

Блин, первое- поменять тел у чела.
Второе, если останется дефект- смотри свою гарнитуру, дальше тел.
Убился апстен смайл(((

Эхо присутствует на всех звонящих мне телефонах.
Все остальное мимо — дело не в гарнитуре и телефоне.
Когда отключаю микрофон в телефоне эхо пропадает.
