Possibly important:
using raring 13.04.
issue seen on hp DV6 7000 series laptop which had beats audio (4
channels i think. it has a subwoofer. info from hp is very unclear).
I am using the alsa daily package: oem-audio-hda-daily-dkms which builds
a new snd-hda-intel kernel module every so often.
----
with the snd-hda-intel kernel module provided by the normal raring
ubuntu repo, the mute/sound led works correctly, but the channels that
the hardware has are not correctly detected, and headphones do not
work/mute speakers. My laptop has multiple speaker channels, and
sub/LFE. With the normal raring kernel module, there is no way to use
all channels even with hda-jack-retask, and sadly sound only comes from
the weakest of the 4 channels so is very disappointing.
I have the alsa daily package ppa of oem-audio-hda-daily-dkms set in my
software sources, so I whenever they release a new build I install it
automatically. With the package from this PPA there are more channels
seen in alsamixer, although i still need to use hda-jack-retask to get
sound from them all. Crucially, the headphones jack works with the
module built from this PPA, and automutes the speakers when headphones
are plugged in.
I raise this bug because non-technical users would not have been able to
get acceptable sound from this laptop using ubuntu, which is an
undesirable situation.
however, the led now always indicates red for "muted" when it should be
white for "unmuted". pressing the mute button toggles the mute function
correctly in pulse/gnome, but the LED always indicates muted.
Essentially, the snd-hda-intel module from this PPA is usable with a
technical modification, but the led indicator does not function
correctly, although it did before.
please let me know if more information is needed, or if you need my to
perform any tests.
kind regards
