Unlocked notification fires on emscripten upon successful resume of
audio context attached to a device.  This occurs only once per device
and it happens after the browser has received the input event
necessary to begin playing audio on most webpages.  This is due
to autoplay rules.

It is recommended to wait until this event is fired to start a
'main game loop' on the web.

This also fixes a possible crash during initialization due to leaving a
thread running after early termination of the initialization routine.

When seeking, the seek does not immediately get applied to the data
source. Instead it is delayed. This results in a situation where the
sound can be seeked, but a small window will exist where querying the
seek point will not be consistent with the previous seek request.

If the state miniaudio side of the device does not match the actual
state of the backend side of it, such as when the device is stopped but
the backend doesn't post a notification, attempting to stop the device
might result in a deadlock.

This is a just a quick workaround hack for the moment while a more
robust solution is figured out.

The SSE2 code paths for mono expansion introduced in Version 0.11.15
mixed up the parameters of `_mm_shuffle_ps()`, which in turn caused
adjacent PCM frames to be swapped in the channel-expanded output.
