[alsa-devel] [PATCH] ALSA: Support Media Vision Jazz16 chips
Rask Ingemann Lambertsen
rask at sygehus.dk
Mon Mar 26 23:23:23 CEST 2007
From: Rask Ingemann Lambertsen <rask at sygehus.dk>
- Add support for Jazz16 features to the common SoundBlaster
code.
- Add a front end for Jazz16 based sound cards.
Tested with a Jazz16 based sound card and Linux 2.6.20.
Signed-off-by: Rask Ingemann Lambertsen <rask at sygehus.dk>
---
This patch is a prerequisite for the Jazz PnP patch, which needs the
patched include/sound/sb.h.
