I want to access the Mic device by using the /dev/dsptask/pcm_rec device file but when i enter:
in a terminal, the resulting file is empty.
So i assume the Mic is muted by default.

How can i unmute it?


Important:
I want be able to do this with a fresh base install of Maemo Diablo.
Because at the moment i can't install additional software like a recording software on my N810.
That's why i try to record from the raw device file.
