Comment 24 for bug 1801540

A partial workaround which doesn't completely fix the issue but improves things is the following:

Adding to /etc/pulse/default.pa, use_ucm=0 tsched=0 right after module-udev-detect

and /etc/pulse/daemon

resample-method = src-sinc-best-quality
default-sample-format = s16le
default-fragment-size-msec=80
default-sample-rate = 48000

Don't know which what specific parameter improved this, because when I test each one of those singularly doesn't totally fix the problem.

The best results I can obtain are with all those combined
