Media server or Audio driver issue, Disappearing sound


Using Nightly build hrevr1alpha4-44687 and M-Audio Delta 1010 LT Sound card.
I have this weird issue after 10-15 hours of uptime sound just disappears. No debug console, no error messages, no nothing. Reboot fixes it for another 10+ hours.


  1. What could be wrong?
  2. How can I track the weak spot?

Does restarting media services (in Media preflet) fixes this problem?

No, Media services restart doesn’t fix the problem. Listdev still has ICE1712 listed. Everything seems ok except there simply is no sound.
So how can I track, what is wrong?

Please create a ticket about this issue at

Do you run the ice1712 driver or OpenSound ?
