Status of backend Audio (dolby pro logic II)

[trihy]

Hi guys, the other day changed audio backend to openAL, selected dolby pro logic II and works great in mutichannel.

But noticed on some games, ie beatles rock band, didnt  get any sound, then distorted and weird sound and after a minutes, sound was perfect for the rest of the game.

So, it´s openAL backend needed for dolby por logic II sound? Or can be done with xaudio2?

If openAL is needed, is still in development, should I report bugs? Should I set latency to 2 on a high end pc?

Thanks!
