| So have noticed some 1 second periodic dropouts playing back from my home brew VB box using HRT II DAC. Tailing the logs confirms that the drop out coincides with these messages: messages:Oct 15 14:57:36 vortexbox kernel: [162421.146863] ALSA sound/usb/endpoint.c:203 cannot submit sync urb (err = -27) messages:Oct 15 14:58:39 vortexbox kernel: [162484.144574] ALSA sound/usb/endpoint.c:180 cannot submit urb (err = -27) messages:Oct 15 14:59:42 vortexbox kernel: [162547.145171] ALSA sound/usb/endpoint.c:203 cannot submit sync urb (err = -27) messages:Oct 15 15:00:45 vortexbox kernel: [162610.144047] ALSA sound/usb/endpoint.c:180 cannot submit urb (err = -27) The box is a dual core Atom in a Shuttle XS35. This seems to be Fedora 16 related - https://bugzilla.redhat.com/show_bug.cgi?id=798844 This started to happen when Vortexbox upgraded to a F16 based distribution, reverting to F14 the problem goes away which I think exonerates my hardware. At this point I don't know if its more Fedora or ALSA ? Any body else run into this on this list ? |
