System: FreeBSD kaoru 6.0-CURRENT FreeBSD 6.0-CURRENT #192: Mon Dec 20 03:46:53 JST 2004 root at kaoru:/usr/obj/src/sys/i386/compile/KAORU.6.0B.0 i386
USB audio device: Sound Blaster Digital Music (SBDM, Creative Labs.)
>Description:
My SBDM has 6 feature descriptors and can be change 5 volumes separately
(one feature descriptor has mute only).those are volumes,
from line to output, from line to record, from mic to output,
from mic to record and to speaker.
But FreeBSD recognize only:
Mixer pcm is currently set to 75:75
>How-To-Repeat:
>Fix:
At first, you must apply the patch of kern/75274.
After that, apply the patch below.
When This patch was applied, FreeBSD recognize SBDM's volumes as
Mixer speaker is currently set to 75:75
Mixer line is currently set to 75:75
Mixer mic is currently set to 0:0
In this case, two volumes from line to output and record,
and two volumes from mic to output and to record,
share "Mixer line" and "Mixer mic", respectively.
It is difficult to separate these sharing in FreeBSD sound system.
