[solved] 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.

I downgrade Lutris to 5.19 - now it works.
Also i used the DEB installer.

Flatpak can’t use all Libraries, here and there…i try to avoid Flatpak for the future in general.

Lutris 0.5.19 is now an obsolete version. You will not receive official support if you use it.

but it works, if i get no other solution i use it to play my game.
