Summary: [bisected] No sound on HDA Intel (ALC268)
Product: Drivers
Version: 2.5
Kernel Version: v2.6.31-rc1-114-g4075ea8
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Sound(ALSA)
AssignedTo: perex at perex.cz
ReportedBy: brian at xyzw.org
CC: tiwai at suse.de
Regression: No
With a recent kernel, my laptop no longer produces sound from the speakers or
the headphone jack. I have made sure all mixer controls are turned up and
unmuted. I bisected the problem to the following commit:
commit 4a79ba34cada6a5a4ee86ed53aa8a73ba1e6fc51

ALSA: hda - Add amp initialization for realtek auto mode
In the realtek auto-probing mode, the initialization of amp with
some magic COEF or EAPD verbs is applied only when the codec SSID
has valid values to satisfy the realtek's definition.
However, many devices don't provide in that way, thus the device
doesn't work as is.
This patch allows the same initialization code even if the SSID
doesn't pass the bit test. Also, alc_subsystem_id() is changed
just to check and define the type, so that it's called in the
parser, instead of the initializer.
