I have been unable to get my microphone working, and I'm coming here in the
hope that someone might be able to provide some advice.
Here's all the relevant details I can think of at the moment:
This is on a workstation that is not currently using sys-usb, since I don't
have neither a PS2 keyboard nor mouse available.
I have a USB headset as well as a USB DAC connected. Audio output to both the
headset and the DAC works fine (I'm using the DAC for listening to music, and
the headset for phone conferencing).
I have used pavucontrol in dom0 to assign the output and input devices that I
want to the respective VM's. My choice of output device is honoured, so I know
that part of the equation works.
Now for the microphone problem. I select the headset microphone in pavucontrol
in dom0, and while doing so I note that the meter is bouncing back and forth
while speaking, which means that it actually works.
I then start a VM, and run the following from dom0:
qvm-device mic attach <vmname> dom0:mic
I start pavucontrol and audacity in the VM. As soon as I click on “monitor” in
audacity I can see it show up in the VM's pavucontrol session, but:
- I see no activity in audacity
- pavucontrol doesn't show any activity (unlike the dom0 pavucontrol)
- If I click “record” in audacity it doesn't record anything at all, not
even
silence. That suggests that it's blocking when trying to read from the
device.
Does anyone have any idea what is going wrong?
Regards,
Elias
