This causes Nexus 4 and Nexus 9 to end up on the fast path, greatly decreasing audio latency!
This also removes the "atomic audio" setting as the new audio code is lock-free always.
This works around a bug in a Harry Potter game that happens on real
hardware. Thanks to gdmk02 for a lot of testing.
Unfortunately, it'll still fail with certain amounts of free space, but it
does this on a real PSP also.
This is good for any slow storage, including:
* Hard disk spinning up.
* Generally slow (cheap) SD cards.
* HTTP or Samba streaming.
May possibly cause bugs in some cases where timing is unrealistic. That
being said, as long as the game is a UMD game, and there's caching (could
enable memory caching for storage), it should not be a problem usually.
They don't actually work in all games, and this only confuses users.
Also, the default 7 lowers the volume of audio detected as bgm or sfx, but
not other volume. This means that some audio may have played too loud in
some games by default, which will be fixed by this change.
