[Qemu-devel] [PATCH] tests: set QEMU_AUDIO_DRV=none for pci sound cards

[Gerd Hoffmann <kraxel@redhat.com>]

This way the tests run without sound hardware being present
on the build machine.  Even with sound hardware it IMO isn't
very useful to use it in regression testing.  Once the sound
card tests are advanced enougth that they try to actually
play sound we probably want the guests sound output written
to a file (via QEMU_AUDIO_DRV=wav) rather than played on the
build machines sound hardware.
