Since there is a fault on my beagleboard I am unable to capture from the
onboard mic in.
I am trying to use a usb camera on android.video capture is working.I want
to use the uac input as mic on android.
I am able to record from the usb mic by using alsa_arecord .
I am trying to configure asound.conf but I don't understand how it has to be
configured.I tried changing the device name in asound.conf
This is how it looks as of now. Can anyone tell me what are hooks ?
