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 ?

Since there is a fault on my beagleboard I am unable to capture from the onboard mic in.

Hi, vishal:
    For beagleboard onboard, there is only audio linein, so we do audio recording as showing in http://0xdroid.googlecode.com/issues/attachment?aid=383687233943152741&name=beagleboard-linein.jpg&inline=1

 

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 ?

I don't have an uac, so I don't know how to try.  It's cool arecord can work.  In 0xdroid distribution, there is no /etc/asound.conf  and here is an issue fixed before for reference, http://code.google.com/p/0xdroid/issues/detail?id=10     though I may not answer your question about asound.conf

thanks,
-Jeremy
