[SOLVED] Audio glitching on Pi 5

[the_bertrum]

Are you using fixed (0db) output? If so have you tired backing off the "Max ALSA Vol" setting a bit? One of my DACs will click (not sure I'd call it a glitch) at times, seemingly when there is a "lot of music", by which I mean a large range of the spectrum at a high-ish amplitude rather than necessarily a single loud peak. By setting the Max ALSA volume to 94%, these clicks vanish. My understanding of how this stuff works is very basic, but it acts as if there is a gain on the input to the DAC so it clips when driven at 0db, thus requiring an attenuation of the feed to counteract the "gain" on the input.

Probably woeful misunderstanding there, but the upshot is that I got audible artefacts to go away by backing off the Max ALSA Volume, so it might work for you too.
