After almost giving up on Fedora in my Acer Aspire One AO722, I chanced upon a way of making the mic work in Fedora 16 today. (It works in Linux Mint 12 by lowering the volume right channel of mic to 0. This solution isn't working in Fedora.) I got the internal mic working in audacity now.
How do I plug an alsa mic item into pulseaudio and use it as the default pulseaudio input so it could be used in apps like google talk?
Alsamixer shows 5 items in the Capture tab: Mic
, Mic 1
, Mic Boost
and Internal Mic
It looks like pulseaudio has attached itself to Mic
. But I want to attach pulseaudio to Internal Mic
. How do I do that?
I was able to make the mic work by doing to following:
- Run alsamixer
- Select HDA ATI SB (F6)
- Increase volume of both Mic Boost and Capture to Max (pressing w). Switch off Mic and Mic 1. Mic Boost is always on. Switch on Capture and Internal Mic. (Space to toggle)
- Open audacity. Select "HDA ATI SB: CONEXANT Analog (hw:1,0): Internal Mic:0". Click on record, stop and play again, and you should hear back what you just recorded.
The AO722 has two sound cards (One "HDMI" - output only; one "Conexant Card: HDA ATI SB, with Chip: Conexant CX20588" <in the latest version of AO722>)
