Please describe your issue in as much detail as possible:

Steam remote play together streaming doesn't provide sound to the client when linux host is streaming.

On the other hand, streaming Celeste (using remoteplaywhatever) or Quiplash Internashional, the clients do get sound.

Steps for reproducing this issue:

1. Start Crypt of the NecroDancer
2. Invite friend to a remote play together session
3. Notice the client doesn't have sound while the game does generate sound on the host side.
