Having installed, updated and set up a Fedora 19 VM without /dev/dsp, I
am indeed still getting slightly different output than Anthony:

GTESTER check-qtest-arm
oss: Could not initialize DAC
oss: Failed to open `/dev/dsp'
oss: Reason: No such file or directory
oss: Could not initialize DAC
oss: Failed to open `/dev/dsp'
oss: Reason: No such file or directory
audio: Failed to create voice `lm4549.out'

repeated several times.

So it seems I was right and you too, Peter, it's just annoyingly noisy
audio output but definitely no qtest failure.

With Anthony's proposed ossaudio patch both the oss and the audio lines
get suppressed.

On openSUSE with QEMU_AUDIO_DRV=pa I am seeing:

GTESTER check-qtest-arm
pulseaudio: set_sink_input_volume() failed
pulseaudio: Reason: Invalid argument
pulseaudio: set_sink_input_mute() failed
pulseaudio: Reason: Invalid argument

repeated several times, but still no test failure, just the noise.

Meanwhile Marcel and Michael have been working on resolving the test
failures I reported. Once we have agreed on a solution there, we'll need
a v3 since mst's pull included the original version of the qom patch
with incorrect documentation syntax that would now cause silent merge
conflicts - my qom-next has the delta as follow-up fix instead.

Regards,
Andreas
