Emulator

What went wrong?
'audio backend' setting in 'dsp', when changed to 'no audio output' (or any other), automatically reverts back to 'dsound' upon closing/opening the emulator.

What did you expect to happen?
Ideally, 'audio backend' setting should be saved. It should not revert back to 'dsound'.

(When recording (TAS), the best option is 'no audio output', otherwise desyncs may be caused)

What steps will reproduce the problem?
I went to 'dsp'.
I changed 'audo backend' to 'no audio output'. I pressed 'ok'. I closed the emulator.
I reopened the emulator. I went to 'dsp'. It reverts back to 'dsound'.
