Date: Sun, 14 Dec 2003 15:16:12 +0100 From: Stephane Marchesin Subject: Re: [SDL] compile problem with sdl <-> alsa The attathced patch does the trick (although there will have to be code changes when the alsa 0.9 api get deprecated). On a side-note, the good news is that using alsa 1.0.0rc1 solves the previous issues I had with my ac97 via sound chipset.
