If the audio driver finishes initialization before the graphic driver does, this situation becomes permanent. This is a workaround that checks for this situation and corrects it on playback prepare. It has been verified working on at least one machine. BugLink: https://bugs.launchpad.net/bugs/1167270 Signed-off-by: David Henningsson Signed-off-by: Takashi Iwai --- Reading git-diff-tree failed
