Just pointing out that with this patch, audio initialization still
hinders me from starting guests on my Fedora 29 when running under root
(I don't think this patch was also intended to fix that, just pointing
out for me the problem still exists).


ALSA lib pulse.c:243:(pulse_connect) PulseAudio: Unable to connect:
Connection refused

sdl: SDL_OpenAudio failed
sdl: Reason: ALSA: Couldn't open audio device: Connection refused
ALSA lib pulse.c:243:(pulse_connect) PulseAudio: Unable to connect:
Connection refused

sdl: SDL_OpenAudio failed
sdl: Reason: ALSA: Couldn't open audio device: Connection refused
audio: Failed to create voice `pcspk'
qemu-system-x86_64: Initialization of device isa-pcspk failed:
Initializing audio voice failed


For whatever reason, on my Fedora29 root cannot access alsa devices.
Maybe it is a Fedora 29 problem, maybe only my setup is messed up (e.g.
because of an upgrade). The workaround for me is to not run QEMU as
root. (I don't have time to look into the details)
