Hi all!
I'm running Windows 7 SP1 64 bit on D54250WYK as my HTPC setup and I have a re-occuring issue with High Definition Audio Controller (PCI\VEN_8086&DEV_0A0C&SUBSYS_20548086&REV_09). It works on top of HDAUDBUS.sys Microsoft driver ver. 6.1.7601.17514 from 19.11.2010...
Now sometimes the HD Audio Controller works OK, but most of the times when receiver (Onkyo TX-SR508) is off for a period of time (really off, not hdmi through) and then turned on again, the device fails to start (code 10)...
No removing the deivce and re-installing it helps, the only thing that does help is restarting the whole system while the receiver is on. Then all works fine up until the receiver is turned off again...
It worked fine on windows 8.1, but it uses a newer version of the driver...
Any Ideas as to how to treat this issue? Is there an intel driver for this device?
BIOS is 0023...
EDIT: It kinda looks like some kind of S1 / S2 power state wake up, but I'm not too sure - when the issue re-occurs I will copy the device state...
