When I setup the machine I use I read a lot about the issue - the only
proposed work around was to enable/disable.
I played with alsa years ago to understand how it works, but last time I
checked the kernel driver docs I did not find this option. Anyway it is
worth trying. I just do not understand how this indexing works in the
different contexts, but I'll figure out.

As far as you have good driver it always works. I found out the key is to
tell the machine which is your audio card and which model it has.
Why being so frustrated?
The problem I guess is the variety of audio chips out there, some of which
are really cheep (and bad).
I always check the kernel driver doc - but this also changed recently and
got more confusing (at least the intel part)
I am not afraid of the "sleeping dog" - we are friends.

Yes, but you are on a public list and your comment is of no favor to TDE,
neither it is related to TDE in any way.
