Yes - but in Debian PulseAudio is started per user when the desktop interface comes up.

When i have a look in ~/.config/pulse then i find a couple of tdb files.

After installing the package tdb-tools i could get a readable output of this files with tdbdump
The content is not a simple text file but a key/data database that looks like
key(26) = "alsa_card.pci-0000_04_05.0"
Now i have no sound again and the interesting question is where to search for the difference to the last login?
The directory ~/.pulse does not exist in Debian 10.

I think you are configuring /etc/pulse/client.conf and /etc/pulse/daemon.conf ?
The tdb files seems to be generated dynamically.

ALSA is much better known in contrast to PulseAudio.
