[fluid-dev] alsa audio driver only accepting huge period size

[la Fleur]

Hello fluiders !

I'm using fluidsynth for a synthetizer in a professional live show. I recently started using it with a phone running postmarketos. Everything is fine when I use the pulseaudio backend. But when I try to use the alsa audio backend, I get a warning that says "warning: Requested a period size of 64, got 6144 instead". This leads to a huge latency.

I never experienced this problem, although I ran fluidsynth on various platforms (including raspberry pi zero, both with alsa and jack outputs).

Can anyone tell me more about this warning ? Here is the output from `aplay -l` :

Is there a way to get more details from my hardware ?
