Hello People

Any one got any ideas on changes that need to be made to setup the
microphone on an Intel AC97 on board sound card. I have audio working
and i have tried un-muting the microphone but i cant get this microphone
to work.

Any info would be apreciated I have experience with linux servers but I
only recently took the plunge into gentoo for my desktop os. I would
like to get the microphone working because I have conferences on voip
quite often and if i can stop my self from booting back into windows i
will be happy

Thanks

You haven't mentioned what sound system you use.
Assuming you are using ALSA, you need to run amixer to see what exactly
you have unmuted and what is muted.
What you see will tell you what you have to do.
On my box I had to:

#amixer sset Capture Capture cap
#amixer sset Mic Capture cap
#amixer sset Mic Playback mute

The last line is for stop hearing in speakers what you say to
microphone, so it's up to you if you want to switch it of or not.

In addition, AFAIK you may see something like this:

> Simple mixer control 'Mic As Center/LFE',0
> Capabilities: pswitch pswitch-joined
> Playback channels: Mono
> Mono: Playback [on]

so you need to do:
#amixer sset "Mic As Center/LFE" Playback mute

That looks like you've set it to use the general line in as mic. If so try
connecting the mic there

Possibly turn on playback and capture here and turn it up, as you might have
the mic connected here.

Looks OK, turn playback on though for the moment.
