Symptoms
Unable to launch DayZ.
Reproduction
- Download DayZ (free weekend)
- Confirm steam play enabled
- Launch
- Observe popup error after install:

Edit:
While the previous errors were indeed errors I don't believe they are related to DayZ rather how proton was being launched. DayZ does start but crashes while loading possibly still related to XAudio and ALSA.
Leaving this open for now.

Research direction
The report names no source file, test, or entry point. Start by reproducing DayZ with Proton 5.0-7 and reviewing the popup and reported usp10.dll and ALSA errors; done would mean DayZ launches and completes loading without the reported crash.
