So much so that it is not included in the distro.

Tim,

Audio services on Linux can be quite complex and can vary depending on 
the active modules loaded and the sound servers running. Therefore it is 
better to detect this at VM launch time than hard-code it in VM.

I just posted a PR [1] to auto-detect pulseaudio if it is installed and 
running or fallback to OSS service if not. This should work on RPi 
without any VM change (or perhaps the aoss wrapper).

Could you please check and revert if it works for you? Thanks.
