Symptoms

I know this game isn't exactly on steam, but I remembered seeing a wine update saying the sound was fixed for this so I figured i'd test it on my deck, it seems to work outside of 2 noticeable audio issues.

1: Some Sound effects don't seem to play consistently, easiest example is Soldier's rocket launcher, when you fire his launcher, it'll play the rocket sound the first time, but not the other 2 times, then it'll play it the 4th time. On Windows it should be playing the sound effect every time he fires.

2: For some reason at certain points, the background music will cut out for a second or so before resuming playing, I checked it on windows and it should not be doing that.

Reproduction

1: Start the game up, pick Soldier, and fire rockets and listen to how only 1 out of 3 rockets shot make sounds.
2: Start the game up, get into the first level, and listen to the BGM and wait for it to cut out.
