Audio Problems on FC3

Hey guys,

i'm currently having problems with my onboard sound with fedora core 3 (latest kernel)

the sound card is onboard realtek ac97 thingie

Problem 1:

it works fine, i hear crystal clear sound in xmms and mplayer but it only seems to work on one channel? at a time, i.e while watchign a movie/listening to songs i get NO sound from GAIM and then when i stop xmms or whatever all the sounds that should have occured during the song come flooding in 1 after another (this can take a minute of annoying beeps), at the moment i have turned the audio notifications off but this isn't ideal.

Problem 2:

Skype, it's installed fine and works, i can dial a number and connect but my mic doesn't seem to work, i don't know if i need any special program or anything, i've used the default volume manager (i use fluxbox but i think it's a part of the gnome environment) and set mic volume to max, tried it with record on and off but they still can't hear me the other end.

Any help would be greatly appreciated

Problem 1:
Put the following in ~/.asoundrc
pcm.!default {
        type plug
        slave.pcm "swmixer"

pcm.swmixer {
        type dmix
        ipc_key 1234
        slave {
                pcm "hw:0,0"
                period_time 0
                period_size 1024
                buffer_size 4096
That should enable software mixing in ALSA. Then go into GAIM, and into Preferences -> Sounds. The 'Sound method' should be 'Command' and the command should be 'aplay'. (aplay is a command line audio player that uses ALSA natively). Then go into the preferences for XMMS, and make sure the 'Output plugin' is the ALSA one. You should now have GAIM sounds playing over XMMS.

As for problem 2, try using 'alsamixer' as your mixer. Turn everything up, and select the mic channel for capture (hit the space bar when the correct input is selected and it should toggle capture on and off).

Just create one and cut & paste the above info in it.

Also it is alsamixer not alsa-mixer
