Sound seems to be OK today. Not sure what's going on so I'm going to close this issue for now. I may reopen if I work out how to replicate the bug.
Ugh. Still happening intermittently, so I'm going to re-open this and let someone else decide if it deserves to stay open. I'd personally file it under the "paper-cut" category.
Could even be an issue outside of the game coupled with how they generate sound. Have you tried to contact the devs?
Seems to be solved by renaming/deleting Dungeons of Dredmor/x86/libopenal.so.1. I wonder why they bundle that library when it is bundled in Steam SDK (and apparently a better working version).
@kisak-valve I left Dungeons of Dreadmor running for 30 minutes and was not able to reproduce the issue. It has probably been fixed along the years so this can be closed.
Closing per the last comment.
Nothing extracted yet.
Music has a kind of crackly distorted static in the background for about a minute after launching the game. After that the sound seems to come right again.
That seems to be unrelated to what I'm doing in the game, or even whether I've started playing a level yet. The sound just comes right again regardless.
