pulseaudio issue on volla phone - can I change /etc/pulse/daemon.conf

Andrisk

After a while I resumed my investigation of an issue I encounter when running my app eartrainer on volla phone 22 (either 16.04 or 20.04 versions).

The error in the log when the app crashes is like this:

Assertion 'pthread_mutex_unlock(&m->mutex)==0' failed at 
pulsecore/mutex-posix.c:108, function pa_mutex_unlock(). 
Aborting.

I found an issue that seems like it might be the same here :
https://gitlab.freedesktop.org/pulseaudio/pulseaudio/-/issues/1411

But I would like to at least generate pulse.log which I could attach to the bug report. From what I found on internet, the simplest way to get the logs seems to be editing /etc/pulse/daemon.conf (https://askubuntu.com/questions/142859/does-pulseaudio-have-an-error-log). But that is on the read only system partition right? Is there a way to modify the config file without breaking my system?

Note. I also mentioned the issue here: https://forums.ubports.com/post/73886

Many Thanks
