| |
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
