Can't quite enable the new test, this is slightly off in timing, and it's hard to fix since we can't really see or compare the internal state of the scesas driver. But, seems to work very well, so let's get it in. |

Atrac-through-SAS is a special way of playing atrac audio that some games use, most prominently the voices in Sol Trigger but also a bunch of minis, and several other games. Basically, the functions
__sceSasSetVoiceATRAC3and also sometimes__sceSasConcatenateATRAC3are used. See #6511This mode of playback works very differently to anything else, so was a bit tricky to figure out, but I've mostly got it now, with the help of a test: hrydgard/pspautotests#236
There are still some edge cases to fix and logging to clean up before I can get this in.See #20125 for some issues this fixes, will link them properly later.
NOTE: This breaks this technique completely for the old sceAtrac implementation. So don't use that. Unfortunately, this means that some savestates may be busted (with regards to audio, at least).
EDIT: Actually, I think I can keep the old implementation somewhat-working..
