[SDL] don't accept alternate audio formats

Browse Source 
On my PC, the SDL2 build doesn't 'obtain' the S16 format it
requests, but since the rest of the SDL2 frontend expects S16, this
causes the audio to fail. So, instead, I force SDL to accept S16, and
just convert to the native format implicitly.

I also applied this to every sound format setting, since I imagine the
frontend doesn't support obtaining only one channel, or a non 48kHz
frequency.
