No Audio over HDMI

If you are getting the "unable to initialize audio device" error when you play a video, try disabling the navigation sounds in the skin settings. If there is no checkbox for that, add the following in your /usr/bin/xbmc script (or /usr/local/bin/xbmc). export SDL_AUDIODRIVER=null right after: SAVED_ARGS="$@"
VICE / Bugs / #1096 SDL sound driver fails on Windows
https://sourceforge.net/p/vice-emu/bugs/1096/
Using the environment variable SDL_AUDIODRIVER, we can force SDL to use a driver (such as "directsound"), we then get the 'spec' we want, but then the sample size seems to be different from what we'd expect and we get a lot of buffer overflows and a very low-pitched sound and the sync code fails, resulting in what seems like an emulation speed ...

PulseAudio and SDL1.2 vs. SDL2.0 -> SDL_AUDIODRIVER ...
https://github.com/ValveSoftware/steam-for-linux/issues/1849
I can only comment this as a "developer" who looked at the SDL code (1.2/2.0) and at least for me this is the problem why I cannot set it to force pulse, but have to unset SDL_AUDIODRIVER so that SDL uses auto-detection (which at least the last time I check sdl code should at first probe for pulseaudio).
