Hi, I've read through the following threads: - https://linuxmusicians.com/viewtopic.php?f=6&t=18046 - http://linux-audio.4202.n7.nabble.com/Hardware-Soundcard-MOTU-624-AVB-Working-with-Gnu-Linux-Debian-8-7-td103759i60.html Especially in the latter thread georgnk replied with the following: http://linux-audio.4202.n7.nabble.com/Hardware-Soundcard-MOTU-624-AVB-Working-with-Gnu-Linux-Debian-8-7-tp103759p105745.html I'm curious regarding those period clicks/xruns. Reason being that I own a Motu 624 AVB and have been troubleshooting xruns for a couple weeks now. I've ended up filling a bug report: https://bugzilla.kernel.org/show_bug.cgi?id=203659 It's basically about xruns happening within suspiciously regular time intervals depending on alsa settings. Various system optimizations do not make a difference. (RT kernel, realtime priorities, cpu max performance, ...) The attachment within https://bugzilla.kernel.org/show_bug.cgi?id=203659#c9 shows an analysis of of a ftrace-trace, which shows a clear pattern in the interaction between xhci and jackdbus whenever such an xrun occurs. By any chance, does someone else experience "sporadic" xruns even while the system is idle, that are actually of pretty regular nature? Easiest way to verify this is to run cadence in verbose mode and have a look at the message log; specifically xrun messages and their timestamps. Running at higher sample rates and low buffer size speeds up the occurrence of these xruns in my case. -- Goli4thus -- Sent from: http://linux-audio.4202.n7.nabble.com/linux-audio-user-f5.html _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx https://lists.linuxaudio.org/listinfo/linux-audio-user
