With Qubes can I utilise the features of a usb audio device?

[Jimza llep]

One of my main computer joys is listening to music, I use an external sound card with a reasonable quality DAC (Tascam US-122L)

Going back to typical "on board" sound card quality doesn't appeal, so I would love to hear about the possibility of routing audio through an external usb sound card in Qubes (I'm pretty sure I have access to LInux drivers).

If this is not do-able then I will have to a 2nd system just for that (and other) purposes..   Not such a bad thing to have seperate purpose machines.. 
.....Oh the mind taxing variables of conceptualising a feature rich AND privacy/security aware computing life... especially on a tight budget!

This is something interesting. I tried but was not able to get it working. I assigned a usb controller to a VM  http://qubes-os.org/trac/wiki/AssigningDevices, then connected the sound card to that usb socket, no drivers were required. But nothing appeared in pavucontrol of that VM. My external microphone card does appear only in lsusb of the VM.

It is possible to easily use USB/bluetooth audio in Qubes, but *not* with appvms. The supplied appvm template does not support full autoconfiguration of audio devices for some reason (IIRC it was Marek who told me this). The soundcard will be recognized at a low level, but won't be linked up with ALSA or Pulse. No doubt there is a way around this, but I don't know what it is.

OTOH, an HVM running a Linux distro or other OS should be able to use the USB audio just fine. I got Ubuntu working with Bluetooth under Qubes with little fuss, and USB should be even simpler. What's necessary is that the particular USB bus with the soundcard connected to it needs to be assigned to the HVM in the normal way (vm settings -> devices); the HVM will take over that USB bus when it starts.

Yes, autodetection in pulseaudio is disabled in VMs, just to speed up its
startup. But you can try to reenable autodetection with something like:
pactl load-module module-udev-detect
pactl load-module module-bluetooth-discover
pactl load-module module-default-device-restore

This needs to be called after pulseaudio startup, so unfortunatelly
/rw/config/rc.local is too early...

A: Because it messes up the order in which people normally read text.
Q: Why is top-posting such a bad thing?

[Franz]

this give: "20"

pactl load-module module-bluetooth-discover
pactl load-module module-default-device-restore

this last gives "21"
 

but then, if you start pavucontrol there is just the same input device, no new one has been added.

If I digit pactl list it shows modules 20 and 21. Enclose the result of pactl list

If I digit alsamixer -> F6, the USB audio device does not appear. (but I tried it in other copmputers running Arch and Ubuntu and it appears)

I had also tried it months ago without success. I can only get HVMs to recognize assigned audio devices.

[Marek Marczykowski-Górecki]

Ok, this thing about alsamixer means that somehow is wrong on the lower layer
- kernel driver. Anything interesting in `dmesg` output?

[inf...@gmail.com]

Resuming thread cos I got stuck here too (R2)

It would be very useful to have a bluetooth headset fpor telephony in an AppVM

nothing interesting in dmesg that I could see

Any other sugestions to try welcome
