New comment by notramo on void-packages repository https://github.com/void-linux/void-packages/issues/34596#issuecomment-1221608477 Comment: I mean if sndio is installed, but **not** alsa-sndio, then Firefox uses sndio, everything other uses ALSA. As sndiod only opens the card when Firefox is playing audio, then it's nearly the same experience as using pure ALSA. I left these notes for advanced users who want pure ALSA, not Poettering™ sound server suckage.
