mic and camera setup for recording and skype
 
hi everyone,

i have a headset with two plugs (one is the headphones and one is the mic). i plugged them into the front of my case, had a play with alsamixer and got it to a point where anyting i say into the mic i can hear through the headphones, but i cannot record using krec or talk using skype.

any ideas?

(camera questions to follow)

Probably wrong mixer settings.

Please show the output of "amixer scontents".

If you're using the front panel connector, this should be set to "Front Mic".

Looks like the cam is registered as /dev/video0 and working. Did you add your user account to the "video" group?

not sure if trying with mplayer like that is the best way... but cannot get it running under skype or koppete.

Alien Bob 07-08-2009 07:56 AM
Looking at the errors you are trying to force the cam to stream in an unsupported resolution (which fails of course). Try to add no parameters to the command at all, just run:
Code:
mplayer tv://
That works for me.
