Meyer Consulting
>Environment:
System: FreeBSD guru.mired.org 4.5-STABLE FreeBSD 4.5-STABLE #6: Sun Apr 28 08:34:18 CDT 2002 mwm@guru.mired.org:/sharetmp/obj/usr/src/sys/GURU i386
>Description:
The t4dwave driver doesn't record sound.
>How-To-Repeat:
Find a system with a t4dwave in it, and try to record with that card.
>Fix:
This is a partial patch, and isn't a complete solution. Cameron asked
me to submit it as he plans on finishing it. I had to replace the card to
get sound at all on other operating systems running on my test
machine.
