Title:
Acer Aspire 8943G internal stereo microphone doesn't work
Status in “linux” package in Ubuntu:
Expired
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.
