Hm, Gerd's patch seems to only touch audio-specific tests but not the
generic qom-test for instance. What about doing Gerd's setenv() in
Stefan's generic code? Not cluttering the shell call even more would
make it easier to some day convert to an array-based API. Not a priority
though.

Cheers,
Andreas
