Bug Description
The internal stereo microphone in the laptop doesn't work.
A WORKAROUND is to mute one of the two channels - making the microphone input mono only - using e.g. hda_analyzer or possibly pavucontrol. I was not able to get both channels working simultaneously - as one channel's volume gets higher, the input volume gets lower and lower as if the two channels interfered.
There is an existing bug #683901 filled about the stereo microphone.
In addition, the built-in Dolby Home Theater 5.1 Cinematic Surround speakers are recognized at best as 4.0 (not using front center and LFE which is rear center) - only if I select 4.0 from the list in System volume, default is stereo (that's wrong, isn't it?!). I was not able to get these two speakers to work even using hda_analyzer. There is also a bug filled about it as bug #839800 but, as well as the thread at ALSA bug tracker, is dead. In the ALSA bugtracker, I was advised to send a mail to the ALSA mailing list - I tried sending the mail twice but was waiting a year for absolutely no response - the mail wasn't even published in the list if I'm right. I have really no idea what more could I do about it.
Tested on Ubuntu 12.10 - today's build (5th September 2012)
