Option #2 in the link may work with your laptop, but controller passthrough
is hit or miss and someone would have to have the same model of laptop to
say for sure if it would work.
The motherboard of my laptop has only one single SATA controller:
SATA controller: Intel Corporation 7 Series Chipset Family 6-port SATA Controller [AHCI mode] (rev 04)
If I try to use this as a passthrough device in the devices tab of the
settings of a certain qube then my Qubes-OS system freezes immediately
when I try to start this certain qube.
I think the Qube Manager should forbid this. If the situation
in dom0 is as follows (Shell-Pseudocode) then the Qube Manager
gui should stop users being as naive as I was:
if [ `lspci | grep SATA | wc -l` = 1 ] || [ selected_controller_is_SATA ]
then error "passthrough would stop system disk from working"
So for the moment I've given up any hope that I could use my builtin
bluray drive of my laptop in Qubes-OS to work with any optical media.
The next thing I tried was to plug an external USB optical
drive into one of the USB ports.
This also appears fine in the device manager menu similar to the builtin
optical drive before when I put a audio media into that one.
I can assign this sys-usb:sr0 device to the qube with the gnome sound
juicer application installed.
However this will not work either, because the virtual block device
(/dev/xvdi in my case) appears not have some magical properties of
a real audio cdrom this application seems to expect.
Even creating symbolic links /dev/sr0 or /dev/cdrom pointing to
/dev/xvdi are not sufficient enough to trick the program into reading
the content of this device as audio cdrom tracks. The error message
"Sound Juicer could not find any CD-ROM drives to read." persists.
I've also tried other applications: K3B from KDE and clementine.
Best regards (Liebe Grüße), Peter Funk
