Hello!
I am having issues connecting my USB microphone (a ZOOM H1) to idjc
through pulseaudio and jack.
The OS is Debian Stretch on amd64.
Now I have tried to:
pactl load-module module-jack-source \
source_name="alsa_input.usb
ZOOM_Corporation_H1_000000000000-00.analog-stereo
and
pactl load-module module-jack-sink \
sink_name="alsa_output.pci-0000_00_14.2.analog-stereo"
but I get no sound in idjc from the microphone. I am sure I got the jack
connections in idjc wired right.
The sink seems to be working fine.
If I only use my USB mic with pulseaudio, things work OK (I have to
crank up the recording volume a bit,
but sound is fine).
Now I did not know where to start, but I suspect the jack module or
something in jack to be the problem.
pactl lists jack modules like this:
