[REGRESSION] ALSA: firewire-lib: heavy digital distortion with Fireface 800
Between the kernel releases 6.9.9 and 6.10.0, something changed that causes heavy digital distortion on playback from at least ALSA and PipeWire. The rhythm of the music is discernable in the output, so it isn't just random noise. It sounds a bit like bitcrushing, but not quite. The generated overtones appear to be dependet on the sample rate.
I am sorry I can not be more specific, there are no kernel messages this time.
As Mr. Sakamoto recently committed all these changes to firewire he might be able to identify the issue easily, which is why I'd like to ask him to look into it.
Kind regards, Edmund Raile.
#regzbot introduced: v6.9.9..v6.10
