Thanks once again Hannu.
Switching from OSS 4.0 build1015 to 1016 + vmix reduces the hdaudio
interrupt rate from 3000/sec to 384/sec which should help with both sleep
state and throttling power management.

Turns out this is more viable than I originally thought, still need to evaluate
the latencies introduced though. Closing the device may also present the
opportunity to introduce codec power management via the ALC268 Power
State verbs.
thanks and regards.
