Hi there,
Very similar case on my side, I also have:
- this beep when I launched some music/sound or a pause ~10s/restart some sound
- a Bose QuietConfort 35 II connected in BT to my workstation
If it can help on this 2nd case, here the same commands provided by
jimav

Title:
Loud beep in BT headset when connecting and often when sound restarts
Status in alsa-driver package in Ubuntu:
Confirmed
Bug description:
A very loud beep occurs on Bluetooth headsets (at least my Bose
Quietcomfort 35) when initially connecting, and often when sound
starts playing, for example when resuming audio media after stopping
or pausing, or when starting a Youtube video It is so loud as to be
painful and makes using a BT headset uncomfortable.
The beep does not occur when stopping and immediately restarting. (so
related to some kind of background or sleep state?)
Hard-wired headsets (connected to my mobo sound Line Output) do not get any
beeps. So it seems specific to bluetooth or the various audio plumbing parts
used when bluetooth is active.
I tried toggling /sys/module/snd_hda_intel/parameters/power_save
between 1 and 0 (1 is it's normal state), thinking that it might be a
low-level sound driver issue. But setting power_save = 0 does not
make the beeps go away.
STEPS TO REPRODUCE:
1. echo "1" | sudo tee /sys/module/snd_hda_intel/parameters/power_save # in
case it matters (it doesn't)
2. Connect a Bluetooth headset (mine is a Bose Quietcomfort 35)
3. Play any audio, e.g. something on youtube.
stop playing and start playing several times, pausing 5-10 seconds in
the "stopped" state.
It might make a difference by switching tabs in Firefox and then back
(possibly triggering some kind of sleep status for the process playing sound)
[not confirmed]
RESULTS: Loud beep is heard on headset when playing restarts.
