Well, as I'm using pipewire period size is translated with quantum, right? pw-top says 2048, which is really big… And it is something between 3x2⁹ and 3x2¹⁰ Surprisingly, now, that I'm at home, audio sounds okay with realtime kernel. 🙄️ I bet, I' gonna have problems when I'm at work, again. > Personally I have found > that using a period size of the form 3*2^n rather than 2^n can > surprisingly improve results at 48kHz or 96kHz of sampling frequency, > likely due to the timer interval becoming better expressible in terms > of > system ticks and/or milliseconds. > > That can lead to a period size of 256 being problematic and a size of > 48 > samples working fine, depending on the device and drivers in > question. I knew that trick when using jackd but I just can't find a pipewire.conf file to edit on my system (like it is written in https://gitlab.freedesktop.org/pipewire/pipewire/-/wikis/Config-PipeWire#setting-buffer-size ). Yeah, the buffer setting could probably be a clue… Greets!
