Your system information

  • Steam client version (build number or date): 30-10-19
  • Distribution (e.g. Ubuntu): Arch
  • Opted into Steam client beta?: Yes
  • Have you checked for system updates?: Yes

Please describe your issue in as much detail as possible:

When hosting a steam play together sessions, friends can hear sounds from all sound sources like discord, steam voice chat, youtube videos etc.

When connecting to a friend who's hosting on windows, this isn't an issue and I only hear the game

This issue isn't arch-specific since This user on Solus experiences the same issue

Steps for reproducing this issue:

  1. Connect to someone who's hosting on linux, hear everything

Possible solutions

This user mentioned that setting up pulseaudio sinks could be a solution, but I assume this is more a hack, and steam should filter out other sounds natively?

Hello @ThaChillera, per https://github.com/ValveSoftware/steam-for-linux/issues/6670#issuecomment-553022562, please retest this issue.

@kisak-valve It works!

its not ideal, since you guys seem to add a new input device when the game window is selected, which makes discord give a popup to ask whether it should select the different input, which makes me unable to read my messages. but that's way outside the scope of this issue ¯\(ツ)/¯

Thanks for retesting, closing as fixed.

Is there something the host or client needs to do to leverage this fix? I'm using the latest steam beta build (Dec 6 2019, at 03:34:35) on Linux Mint 19.2 and still have this issue when hosting.
