 Posted: Tue Dec 22, 2020 2:24 pm Post subject: jack2 many Xruns suddenly |
 |
|
Hi,
I'm using jack2 with pulseaudio bridge several months without problems.
Suddenly now I booted PC and sound was with breaks, so cause I didn't find reason I rebooted.
Now I have problems to run Jack as usual:
I have Cadence autostart after login, then I clicked Start (to start Jack) and then on JACK Bridges PulseAudio Card - Start.
It worked fine till now.
Now I get 3 Xruns every second.
Thanks in advance  |

Maybe DBus problem? I upgraded system to python3.8 (standard portage system, world update)

Integrated Sound Card works with no Xruns.
It's from China shop - using quality chip but it's possible it's wrong after just several months :-/
Have another with same chip but quality brand. I'll test it soon if it's OK.
(also noticed in log I posted before:)

What scares me - alsamixer on this "wrong" card works OK.  |

| As you pointed out, probably the problem lies in the USB sound card. Polling a USB audio device has a greater distance (or has less priority/bandwidth/etc on a system's buses) compared to a Pcie attached sound card (or the built in sound card). Ultimately what this means is that the USB device can't catch up with the CPU polling. You could increment the buffer size and/or periods/buffer in Cadence until you see no xruns with the USB audio device attached. This will be always be higher than with no USB attached. Unless (maybe) if the audio device is of high quality and is able to communicate with the PC at good enough speeds. |
