Make sure to add appid to title (22380)
Figured out that's the problem by examining the log file, 32 bit MP3 decoding library was missing. Problem can be fixed by issuing
sudo apt install libmpg123-0:i386
Hello @jgacas, we'll be using one issue report per unofficially supported game title, so I've gone ahead and transferred this issue report to https://github.com/ValveSoftware/Proton/issues/356#issuecomment-417636714.
Every time I turn on Radio New Vegas, and speaker finishes talking about latest news, games crashes. At that moment music, that was announced by the speaker, should start playing, but instead games exits to the desktop. Issue is easily reproducible because it happens every time.
