sounds?

[kenny43]

"VAG, MP3, PCM , Atrac3, among some others are the sound formats supported so far, as long as there's no Atrac3+ we will not have BGM on most of the games, all there's to do is keep waiting since all the Atrac3+ decoders are property of Sony, so until devs find an open source decoder or any other way of playing these, we're stuck with the sounds we have so far."

I had posted this not long ago, just copy pasting here so you'd have an idea.
In short, atrac3 (not plus) support was added not long ago throuhgh ffmpeg, that's why many voices and some BGMs are working now, video support'll be here shortly as well.
