Subject: [ALSA hda 3.4-rc] suspend2ram regression in snd_hda_intel
Date: Fri, 04 May 2012 11:21:21 +0400 [thread overview]
Message-ID: <4FA38371.9020205@openvz.org> (raw)
Mainline commit 785f857d1cb0856b612b46a0545b74aa2596e44a
("ALSA: hda - Set codec to D3 forcibly even if not used")
breaks sound for my notebook (thinkpad x220),
looks like codec cannot wake from power-save state after resume.
After reverting looks like all works fine.
how to reproduce:
* unplug the power cord (to enable hda power safe mode)
* play something and stop
* wait until the background noise disappears (codec went into power-save mode)
* suspend
* resume
* play something again and hear the silence
