[alsa-devel] [PATCH] sc6000: add support for SC-6600 and SC-7000
Krzysztof Helt

Sat Apr 4 14:48:32 CEST 2009
The previous patch does not apply to the current kernel.
Here is a new one.
Best regards,
Krzysztof

From: Krzysztof Helt <krzysztof.h1 at wp.pl>
Add support for later cards based
on CompuMedia ASC-9408 chipsets.
These cards were produced by Gallant.
This patch make the OSS aedsp16 driver
redundant.
