This is current/amd64 (dmesg below),
running /usr/bin/sndiod -f rsnd/0 -F rsnd/1
While the -F feature works with most USB audio devices I have tried,
it does not make the switch to use the -F device
with this USB camera with a builtin microphone.
It's an Audom AF640 and it attaches as follows:
uvideo0 at uhub0 port 1 configuration 1 interface 0 "Sunplus IT Co Full HD
webcam" rev 2.00/0.05 addr 2
video0 at uvideo0
uaudio0 at uhub0 port 1 configuration 1 interface 3 "Sunplus IT Co Full HD
webcam" rev 2.00/0.05 addr 2
uaudio0: class v1, high-speed, sync, channels: 0 play, 1 rec, 2 ctls
audio1 at uaudio0
I can confirm that both the camera and the mike themselves work.
After plugging it in, sndioctl says
input.level=0.000
input.mute=1
output.level=0.980
output.mute=0
server.device=0
app/rec0.level=1.000
Notice the server.device=0, meaning it is still using snd/0.
Notice the zero input level and the muted input.
Is this intended?
If I plug a Sennheiser haedset instead, sndioctl says
input.level=0.800
input.mute=0
output.level=0.800
output.mute=0
server.device=1
app/rec0.level=1.000
switching to the USB device plugged in.
Is it because the camera's mike has no output channels?
"channels: 0 play, 1 rec, 2 ctls" - indeed, it only
records mono and has no playback capabilities.
According to the manpage
-F device
Specify an alternate device to use. If it doesn't work,
the one given with the last -f or -F options will be used.
For instance, specifying a USB device following a PCI device
allows sndiod to use the USB one preferably when it's
connected and to fall back to the PCI one when it's
disconnected. Alternate devices may be switched with the
server.device control of the sndioctl(1) utility.
Is the -F device required to have at least one playback
and pne record channel to "work"?
Switching with a manual "sndioctl server.device=1"
doesn't work either: sndioctl still shows server.device=0
Is this intended?
How can I further debug this?
