Bug description

Audio quality is very poor when using video calling. This is always the case, regardless of whether I use mobile data or wifi. This appears to be due to a lack of background noise cancellation when video is on.

Steps to reproduce

Open signal
Start audio call to a contact
Ask contact if they can hear you
Turn on video
Check audio quality with contact again

Actual result: Poor/indecipherable audio Expected result: Good quality audio with no background noise

Device info

Device: Fairphone 4 Android version: CalyxOS 4.12.1 Signal version: 6.31.2

We have experienced similar issues in the past with the Fairphone 2, and the resolution was not relying on the hardware's automatic echo cancelation.

I've gone ahead and added the Fairphone 3 & 4 to the list, which should take effect globally in 6-12 hours. Let me know if that helps!

That was a quicker response than I expected! I just tried a video call, didn't notice much improvement, tbh. Was an update required? I haven't seen an update listed on F-Droid.

It should have taken effect when the app refreshes its configuration., which usually takes place every 6-12 hours.

Oh, I see. Not really familiar with the inner workings of Android. I made one or two more calls since, they seemed to have better quality audio. But I want to leave this issue open a bit longer, just in case.

I have tried using video calling several times since the configuration change 2 weeks ago, but there is still excessive feedback causing a high-pitched squeaking noise. I have applied the usual recommended settings, use less data, etc. But the feedback is still there.

I see in your new logs that automatic echo cancellation is indeed disabled, but clearly that has not resolved the issue. We'll see if we can source a Fairphone 4 here in the USA.

Just keeping this issue alive, as not solved. Please remove automatically added wontfix label unless there is actually no plan to fix it, in which case I would like to know from a maintainer or contributor, instead of a bot.

I wondered if it might have something to do with latency of the network connection. I have a VPN on by default, which I usually forget about. I have tried calling with the VPN off and with a different VPN connection optimised for P2P. Both had much lower latency (<20 ms as opposed to 200-400 ms, based on speedtest.net under load), and the call quality on my end was much better, no audio feedback. Is there some more definitive test I could do on my device to help confirm this? Since I already have a Fairphone, would save someone having to get one just for testing purposes.
