I am implementing power management in my ALSA sound drivers. ALSA
drivers are not working properly after resume. All registers values
are proper and I am able to read back the codec register contents.

If I do a playback after resume then I am getting lots of "underrun".


After a reboot playback is working fine.

Is there any known issues with ALSA power  management?
Why Ubuntu and Redhat does ALSA modules removal before suspend and
insertion after resume?
