Subject: Access to bytes from the raw audio stream? (AC'97)
Date: Wed, 3 Feb 2010 16:08:38 +0000	[thread overview]
Message-ID: <94cf76f1002030808t1d54dc08oab179673e814f016@mail.gmail.com> (raw)

Hi there,

I'm new to ALSA, and working on a project where I need to find out
where I can see/modify the raw bytes coming in from/going out to a
device. The device is an AC'97 codec (a philips UCB1400, if it makes
any difference...) on an embedded board.

I tried looking on the web, and found the tutorial at
http://www.alsa-project.org/~tiwai/writing-an-alsa-driver/, but that
seems to be more about device management and configuration.

So, can anybody tell me what functions and files in the sound/
directory of the linux kernel I need to look at to see/modify the raw
data stream coming in? Am I just missing something in the tutorial?
I'd appreciate any suggestions very much.

Thanks,

John Graham
