I've posted this message here although I don't think the problem is specific to v3.10. The issue has been intermittent but persistent even after upgrading from earlier versions in the hope I've fixed it. What happens is that periodically the sound stops even though everything else seems to be working fine. It usually comes about as a result of me pausing the music but then, when I reboot, it does not come back until I have rebooted several times.
My setup is an Rpi2 with an IQaudio DAC and IQaudio Amp with a 7" screen and IR control. I have done some analysis and the dmseg logs are different between the no-sound and sound situations. Those logs are the same up to 4.3 seconds. Then there is a gap and at 13 seconds the logs differ. In the no-sound condition these lines appear.

Might be something be causing this intermittent fault to occurs and if so, any suggestions how I might fix it? many thanks ------------------------------------------------------------------------ kingswindsor's Profile: http://forums.slimdevices.com/member.php?userid=61926 View this thread: http://forums.slimdevices.com/showthread.php?t=106755 _______________________________________________ unix mailing list unix@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/unix
