First of all, sorry for my english.
I'll do my best, but I'm french and my english is not really fluent.
I'm using Wine since several years and all worked pretty well until yesterday.
I'm using Debian Buster

And Wine deals with every things without troubles.
BUT, for the needs of a game, I've had to set a new regedit key :
//HKEY_CURRENT_USER/Software/Wine/Drivers/Audio = alsa
With this key added, the game work fine and the sound was good in the game (with Wine), and on my Debian.
The things gone wrong at the next reboot : no more sound.
At all.
When I look at the output interfaces, the "Line out" was replaced by a "Line in" (in the output interfaces !!)
Line in = Entrée ligne in French, and "Sortie" means "output".
I know it really strange, but I've reinstalled my Debian from scratch and sound works well until I set this regedit key one more time.
Is it possible Wine changes Pulseaudio "sinks" ? Or Alsa interfaces ?
Any ideas to get sound back without a full reinstal (again) ?
I've tried to remove (and purge) PulseAudio and firmware-misc-nonfree (where the CA0132 is), nothing works...
Any clues ?
Best regards,
