Original GitHub issue: https://github.com/games-on-whales/wolf/issues/309

No sound on the Moonlight UWP Xbox client, not even in Test Ball. Selecting a sink in Steam doesn’t produce any results.
Sometimes the sound appears for a second when connecting to Test Ball and then immediately disappears.
Is this an issue related exclusively to this client? There is no such problem on other clients.

Are there any possible solutions to this problem?

The logs when launching Test Ball show the following:
