Summary: Acer Aspire One: microphone only works after turning
left microphone channel off
Product: PulseAudio
Version: unspecified
Platform: x86 (IA32)
OS/Version: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: core
AssignedTo: pulseaudio-bugs@lists.freedesktop.org

I'm running pulseaudio 0.9.23 on Archlinux on an Acer Aspire One 150. Sound is
handled by the snd_hda_intel module.
In the default configuration, everything _seems_ to be fine - the microphone
input is shown correctly, volume sliders work - but there is no actual input.
After some googling, I stumbled over the following post:
http://getsatisfaction.com/jolicloud/topics/deaf_internal_mic_on_acer_aspire_one#reply_2108048
After using pavucontrol to reduce the volume of the left microphone channel to
0, microphone input suddenly appears and works as intended.
This seems to be an incredibly obscure fix for somewhat common hardware and
should be handled correctly without workarounds.
If you need more information or if I can help in any way, please let me know.
