** Description changed:

  The internal stereo microphone in the laptop doesn't work.
  
- A workaround is to mute one of the two channels - making the microphone
+ 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 interferred.
+ 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 (unusing 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 to work 
even using hda_analyzer. There is also a bug filled about it as #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.
