Hi! I'm currently testing the snd-fireface module on kernel > 5.9 with the RME Fireface 800 (FF800). Unfortunately, when running jackd using that device it generates large bursts of Xruns (~10000) quite periodically. /usr/bin/jackd -P80 -p 512 -d alsa -d hw:Fireface800 -n 3 -p 256 -r 48000 The issues do not seem to correlate with any load events on the system (and in between the Xrun events there are no Xruns even under load). I am not entirely sure how to further debug this. Any hints and suggestions would be very much welcome! Note: While using libffado for the device works it is not at all stable since kernel > 5.9 (sporadic rediscovery events of firewire-ohci, requiring the unplugging/replugging of the device's firewire cable and of course the restart of jackd). This is why I tried the snd-fireface module again, but it seems to suffer from a different set of issues ;-) Best, David -- https://sleepmap.de
