Debian 13 - Alsa - Pipewire - no sound in Battle.Net - Flatpak

I read about an unsolved Issue with Debian 12 Bookworm, where i had sound on MX Linux 23.

Now i “quick” installed MX 25 and set up the System in 1 Day up to Battle.Net.

I only have no Sound in Starcraft 2 (latest GE Proton without any Version number on it), was also Quick install, restore from a Backup,
installed Lutris and wine-tricks and pointed to the Folders.

I have perfect Sound in Firefox, System and Audio Workstation - all together.
Not in the Game. There is also only “STANDARD” Audio Setting available in the Game Settings.

$ inxi -A
Audio:
  Device-1: Intel Raptor Lake High Definition Audio driver: snd_hda_intel
  Device-2: NVIDIA driver: snd_hda_intel
  Device-3: Micro Star USB Audio driver: hid-generic,snd-usb-audio,usbhid
    type: USB
  Device-4: AKAI Professional M.I. MPK mini 3
    driver: hid-generic,snd-usb-audio,usbhid type: USB
  API: ALSA v: k6.12.74+deb13+1-amd64 status: kernel-api
  Server-1: PipeWire v: 1.4.5 status: active

StarCraft Protocol most relevant Error says:

gamemodeauto: dlopen failed - libgamemode.so: cannot open shared object file: No such file or directory
ALSA lib conf.c:4133:(snd_config_update_r) Cannot access file /usr/share/alsa/alsa-flatpak.conf
ALSA lib pcm.c:2660:(snd_pcm_open_noupdate) Unknown PCM default

i will update or downgrade alsa then.

Edit: This Folder/ Fille ()alsa-flatpak just did not exist:

user@hahn:/usr/share/alsa
$ ls
alsa.conf  alsa.conf.d  cards  ctl  init  pcm  topology  ucm  ucm2  utils.sh

$ sudo touch alsa-flatpak.conf ?!?!??!?!?

i also found the error cannot something libgamemode0 so i found this package here"libgamemode0".

And i try it again. Seems not work so i reboot.

:Same no Sound still

Cya Later.

Try out different Wine-Options
startet Game with the SYSTEM (11) Setting,
now needed to install wine-mono,

also got now my Audio Setting in the Setting.

I hang a bit on Loading the Battle.Net Login.
Wine flickering with a DOS Window…

Mabe perform a restart or reboot.
