[2.1.9] Sound doesn't play if any other program is playing sound

[DreadY2K]

If some other program is making sound (e.g. I'm watching a youtube video) when I start the game, then it doesn't play any audio (neither music nor sound effects). Once the other audio source stops (e.g. I pause the youtube video), then it suddenly plays all the sound effects that should have played before, which gets very loud, then starts playing audio like normal. If no other audio is playing when I boot the game, then audio works normally.

I first noticed this when I switched to the 2.1 experimental version of the game. It doesn't happen on 2.0.

My computer is running Manjaro 26.1 and KDE Plasma 6.6.5, and the `uname` output is:
```
$ uname -srvpo
Linux 7.0.10-1-MANJARO #1 SMP PREEMPT_DYNAMIC Sun, 24 May 2026 04:47:00 +0000 unknown GNU/Linux
```

Update on this: I just noticed the "Preferred audio driver" setting, and I set it to "ALSA" and audio now works as I'd expect. Probably still worth investigating why the default didn't pick the correct one for my system, but at least my game works correctly now
