From a1f3f1ca66bd12c339b17a0c2ef93a093f90a277 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Sun, 8 Mar 2015 18:29:50 +0100 Subject: ALSA: hda - Fix regression of HD-audio controller fallback modes The commit [63e51fd708f5: ALSA: hda - Don't take unresponsive D3 transition too serious] introduced a conditional fallback behavior to the HD-audio controller depending on the flag set. However, it introduced a silly bug, too, that the flag was evaluated in a reverse way. This resulted in a regression of HD-audio controller driver where it can't go to the fallback mode at communication errors. Unfortunately (or fortunately?) this didn't come up until recently because the affected code path is an error handling that happens only on an unstable hardware chip. Most of recent chips work stably, thus they didn't hit this problem. Now, we've got a regression report with a VIA chip, and this seems indeed requiring the fallback to the polling mode, and finally the bug was revealed. The fix is a oneliner to remove the wrong logical NOT in the check. (Lesson learned - be careful about double negation.) The bug should be backported to stable, but the patch won't be applicable to 3.13 or earlier because of the code splits. The stable fix patches for earlier kernels will be posted later manually.

In the driver code, we do care the mono channel and create a control only for the left channel (as defined in HD-audio spec) for such a node. When the control is updated, only the left channel value is changed. However, in the resume, the right channel value is also restored from the initial value we took as stereo, and this overwrites the left channel value. This ends up being the silent output as the right channel has been never touched and remains muted. This patch covers the places where unconditional stereo amp accesses are done and converts to the conditional accesses.

In this case, it has stereo volumes although it's a mono widget, and thus we have to take care of both left and right input channels, as stated in HD-audio spec ("7.1.3 Widget Interconnection Rules"). This patch covers this missing piece by adding proper checks of stereo amps in both the generic parser and the proc output codes.
