wasapi: Fix double call to Start when resetting the element
When either the source or sink goes from PLAYING
-> NULL
-> PLAYING
, we call _reset()
which sets client_needs_restart
, and then we call prepare()
which calls IAudioClient_Start()
, so we don't need to call it again in src_read()
or sink_write()
. Unlike when we're just going PLAYING
-> PAUSED
-> PLAYING
.
