snd_start_digital() opened two separate SDL audio devices - a raw one
for cutscene/audiolog audio and a second via Mix_OpenAudio() for
SFX/MIDI - but Android's audio backends only ever allow one open
non-capture device, so the second open always failed silently.
- Consolidate onto a single Mix_OpenAudio() device; cutscene/audiolog
PCM is now mixed into its output via Mix_SetPostMix() instead of a
dedicated device (16-android-audio-single-device.patch)
- Add SDL_GetError() to the failure log so a future open failure is
actually diagnosable (15-android-audio-error-detail.patch)
- Make NativeMidiInit() report failure on platforms with no real
implementation (Android included), instead of silently claiming
success without opening anything (17-android-native-midi-unsupported.patch)
- Strengthen the OpenSL ES driver hint to SDL_HINT_OVERRIDE and log the
active audio driver as a standing diagnostic (05-android-audio-driver.patch)
