ALSA: hda - Disable runtime D3 for Intel CPT & co
Browse files Browse the repository at this point in the history
We've got a few bug reports that the runtime D3 results in the dead
HD-audio controller.  It seems that the problem is in a deeper level
than the sound driver itself, so as a temporal solution, disable the
feature for these controllers again.
