Bug ID: 279787
Summary: Can't select SPDIF input of USB sound card with 14.x
Product: Base System
Version: 14.1-RELEASE
Hardware: amd64
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: usb
Assignee: usb@FreeBSD.org
Reporter: f...@ogris.de
I am no longer able to select "pcm2" (which is SPDIF input on my USB sound
card) nor "line2" as recording source on 14.1-R (nor 14.0-R). mixer(8) does not
report these input sources anymore:
# mixer
pcm0:mixer: <vendor 0x0d8c USB Sound Device> on uaudio0 (play/rec) (default)
vol = 0.75:0.75 pbk
pcm = 0.75:0.75 pbk
line = 0.75:0.75 rec
mic = 0.25:0.25 rec src
Trying to set pcm as recsrc:
# mixer pcm.recsrc=set
mixer: pcm.recsrc=set: Operation not supported by device
usbconfig and /dev/sndstat:
# usbconfig
..
ugen0.3: <CM106 Like Sound Device C-Media Electronics, Inc.> at usbus0, cfg=0
md=HOST spd=FULL (12Mbps) pwr=ON (500mA)
# cat /dev/sndstat
Installed devices:
pcm0: <vendor 0x0d8c USB Sound Device> (play/rec) default
No devices installed from userspace.
I already tried setting usb quirk UQ_AU_SET_SPDIF_CM6206 during runtime and in
loader.conf as suggested on the forum.
Various external USB sound cards from different vendors show that same
behaviour.
On another host running 13.3 from memstick:
# mixer -h
usage: mixer [-f device] [-s | -S] [dev [+|-][voll[:[+|-]volr]] ...
mixer [-f device] [-s | -S] recsrc ...
mixer [-f device] [-s | -S] {^|+|-|=}rec rdev ...
devices: vol, pcm, line, mic
rec devices: line, mic, pcm2, line1
# mixer =rec pcm2
# mixer recsrc
Recording source: pcm2
# usbconfig
..
ugen0.10: <vendor 0x0d8c USB Sound Device> at usbus0, cfg=0 md=HOST spd=FULL
