1. Prevent ALSA audio corruption …

   When using the ALSA driver, corruption would occur if `snd_pcm_writei`
   was unable to consume the entire sound buffer. This would occur
   frequently on the Raspberry Pi 3 which uses the `snd_bcm2835` audio
   driver.
   
   This bug resulted from incorrect pointer math on line 187, resulting in
   the sample source pointer being advanced by `total * ad->channels` bytes
   instead of `total * ad->channels` samples. In my opinion, the best fix
   is to change `*src` to type `int16_t`, since that is the sample type in
   use.
   
   Fixes godotengine#43927.
