Subject: [gentoo-user] OT: What does the data stream to a sound card look like?
Date: Sat, 28 May 2011 09:50:44 +0000	[thread overview]
Message-ID: <20110528095044.GA3946@acm.acm> (raw)

Hi, Gentoo.

It occurred to me the other day that I am clueless about how a sound
card works.  How do the data get into it?  Does the sound card use an
interrupt to ask for more data?

What form do the data take?  Say I feed an mp3 through the card.  Does
the Athlon do the decompression, or does the sound card do it?

Last of all, is there a command line program which can play a CD by
feeding its data into the sound card?

Thanks for any and all enlightenment.
