Comment:
In case someone runs into this, I have found a simpler solution.
1. Install and start `sndiod`
2. Firefox will automatically use it
3. If the sndio ALSA plugin is not installed, then the other apps will still use ALSA.
4. Only problem is that it can't play audio from multiple apps simultaneously if your card doesn't support mixing (but this is a problem with pure ALSA too). Also, if the sound card was used by another app at the time Firefox wants to play audio, you have to restart Firefox (closing the other app is not enough).
