Audio CD via USB drive

[timo.ve...@googlemail.com]

Hi qubes-users!

I'm trying to extract audio from a cd on my qubes (3.2) notebook. After reading thru the various pages of the docs section and searching the mailing-list, I thought the following setup would be my best option:

* usb-dvd-drive attached to a USB 2 port
* use a sys-usb vm
* attach the drive-device via qvm-usb to a target appvm (fedora-24 based)
* start "sound-juicer" in appvm to extract audio

Unfortunately, I now have to following problem: When I insert a cd into the drive, qubes immediately takes control of it, so that sound-juicer can no longer access the drive.

I can see, that a /dev/sr0 device pops up in the appvm, which the sound-juicer app then tries to access. But qubes attempts to expose the drive as a block device makes it unaccessible to sound-juicer.

Is there a way to prevent this? E. g. prevent qubes from exposing a certain device in a certain appvm?

Best regards,
Timo

Not sure if this is an option for you, but have you tried running Sound
Juicer in sys-usb?

I tried it already with the same result.

Is there no way to prevent Qubes from exposing a block device?

This is a known problem in Qubes. I had similiar problem with data CDs with no solution. Gave up.
