I understand, but I think you might find a way to break sound yourself by altering the settings in the ".alsoundrc" file that is in appdata/telegram/home
I was getting a little annoyed with PND system using appdata for the home directory, because if I want to propagate any of my gtk theme settings into a PND, I need to copy or link files from my home directory to the appdata directory.
However, your comment gives me an idea that I am excited to try:
Use the home directories in appdata to have PND-specific .asoundrc files.
I could have the audacious .asoundrc point to bluetooth as I really only use audacious for playing bluetooth audio, and then use the system-wide ALSA settings for everything else (I already use a script to switch back and forth between bluetooth and hardware at the system level).
Using this method, I should be able to play game audio out from hardware while sending bluetooth audio out of audacious, which is perfect for those games that fail to run when bluetooth audio is enabled!
