USB devices are allowed to reserve bandwidth... and that affects every device attached to the same USB hub. Now, you might say, "I don't use a USB hub" -- but that's not true. Your PC has one or two USB hubs that it uses internally. In my case, I had a USB audio device on the same hub as a USB Webcam. Even when I wasn't using the Webcam, it was reserving bandwidth. Thing would be running fine, then all the sudden audio comes crashing down with an xrun. For me the PC had two internal hubs. I used a different USB port (attached to the non-webcam-hub) and the problem was solved. I'm not saying this is your problem... but use something like 'sudo lsusb -t' and inspect which devices are connected to which hubs. Unplug as much as you can. Try different ports. -gabriel _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
