Sound playback/recording issues
-
I and my wife are using Redmi Note 9 Pro on a daily basis after migrating from Nexus 5 (half of a year and one year respectively). We have a good experience in common but the one thing is very annoying, and I couldn't bring myself to report it yet.
When using the device, suddenly Camera app stops recording audio so the video file is silent during playback (and nothing helps). Looks like it's simply not being recorded. At the moment, I can't tell under which circumstances it happens exactly but can say that it may happen few times in a day (and even few minutes after reboot). The only way I found to temporarily fix the issue is to reboot the device. So each time we need to record some significant video where sound is important we're going to reboot the device first to minimize the risk of sound not being recorded.
Another problem is that (also suddenly) the device stops playing the sound at the right volume. The sound becomes too quiet in videos and TELEports voice notes so it's almost impossible to distinguish the sound especially when some external noises are around. And the only way to "fix it" is also to reboot the device. Volume buttons don't help because Ubuntu Touch shows that sound is already at the highest volume.
I would be very grateful to you, guys, if you can help to solve the issue or, at least, recommend some steps to narrow down the problem. I am a little bit surprised, to be honest, that nobody has addressed this one yet here (because I am experiencing it on two Redmi Note 9 Pro devices but not on two old Nexus 5 or BQ Aquaris M10). Does it mean that almost nobody use the device on a daily basis?
Unfortunately, recent updates to OTA-24 also didn't help.
I found that it's the only real alternative to my old Nexus 5 in our region so I dream of these issues being fixed in the nearest future.

I have a Note 9 pro and I also have these problems, restarting some things are fixed, I have noticed that it happens because some apps disturb others, I mean if I'm with the media player and turn on the camera, everything continues until I close the camera app, at that time the volume of the entire system is lowered, so the media playback works at very low volume, it also happens with the Puremaps navigator. I think that some sound apps interfere with others.

The recording affects some other halium 10 devices too.
See this issue for a temporary fix https://github.com/ubports/ubuntu-touch/issues/2022
About the low audio, never had it myself, make sure you don't have the camera app in the background when playing audio, or don't play from multiple sources at once.
A quick fix is also restarting pulseaudio with
pulseaudio -kinstead of rebooting
