But that's only a guess on my part. Unless I shutdown all the VMs and
possibly also reboot the system to ensure nothing is left in the way I
won't know.

Certainly, I do get that in my case it did read the whole disk but I
use cdda2wav to copy CDs all the time so in my case I have no doubt
that program works. However cdda2wav continuing to do the copying when
it couldn't access the playback device seems like a bit of a waste,
but fixing it likely isn't worth the effort.
It would possibly be valuable for Colleen to run the same command also
just to compare.
