Hi,
I've got a strange problem with raydat on latest fedora 64bit.
At some time the card stops playing, and all settings in amixer are messed up, like reported.
I have to reset my pc to let the card play again.
If I remove and then reload hdspm module the pc hangs.
my box is a new core i7 sandy bridge:
As you see below system frequency is messed (24414 Hz)
input status is very strange.
Firmware is version 12

asus p8z68 v pro gen3
16 GB RAM corsair
intel core i7 2700K

Thanks for your help.
