["Christopher M. Penalver" <christopher.m.penalver@xxxxxxxxx>]

Lukáš Chmela, this bug was reported a while ago and there hasn't been
any activity in it recently. We were wondering if this is still an
issue? If so, could you please test for this with the latest development
release of Ubuntu? ISO images are available from
http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please just make a comment to this.

Also, could you please test the latest upstream kernel available (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.12

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your
understanding.

Title:
  Acer Aspire 8943G internal stereo microphone doesn't work

Status in “linux” package in Ubuntu:
  Incomplete

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.
