Subject: [ALSA] ALSA Power Management, Drivers behaving unexpectedly after suspend/resume cycle
Date: Fri, 25 May 2007 11:27:10 +0530 [thread overview]
Message-ID: <8d6898730705242257k6da2088fi80f0d4034ed78986@mail.gmail.com> (raw)
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?
