>Category: kern
>Synopsis: No support for MAD16 audio chips.
>Confidential: no
>Severity: non-critical
>Priority: medium
>Responsible: kern-bug-people (Kernel Bug People)
>State: open
>Class: sw-bug
>Submitter-Id: net

>Organization:
CS at Chalmers University of Technology
>Release: NetBSD 1.1 current, 1996 Jan 31
>Environment:
System: NetBSD calvin.cs.chalmers.se 1.1A NetBSD 1.1A (CALVIN) #29: Thu Feb 1 12:52:52 MET 1996 augustss@calvin.cs.chalmers.se:/usr/src/sys/arch/i386/compile/CALVIN i386
>Description:
There is no support for the MAD16 (82C929 etc) audio chip sets.
They can emulate both SoundBlaster and Windows Sound System.
WSS is better.
>How-To-Repeat:
Just try using a card with one of those chips (I've tried miro PCM10).
>Fix:
This fix adds code to the wss driver to look for MAD16 chips.
To make the driver probe for it you need a "flag 1" on the config
line for wss. I.e.
device wss0 at isa? port 0x530 irq 10 drq 0 flag 1
The code is based on the VoxWare driver.
