I think the easiest way is to forward the sorted driver list as string
to the audio layer and let it be processed there. Given such an
extension, we could also allow passing a list of drivers via QEMU_AUDIO_DRV.
BTW, I still wonder why we have OSS and only OSS as the default driver
list under Linux. Most distros I came across kicked it out or pushed it
to the end of their list (as it requires exclusive access). Would be a
chance to improve the default. At least we should extend the list by all
available drivers.
