[alsa-devel] Mic + Headphone Problem in Samsung R540

[Valentine Sinitsyn]

Hello,

Looks like your Capture switch is disabled. Run alsamixer, find Capture 
(press F4) and then press Space to start capturing sound. Obviously, you 
will need to run arecord after that (I recommend using -vv to see the 
bar moving as you speak anything into mic).

P.S. You shouldn't send messages to alsa-devel-request email, it is 
intended for list management functions.

Regards,
