Just got 5.1 and am trying it out . XP Pro SP3 and a old crappy but does the job soundblaster live. Been using SX3 for a while and the current ASIO4all drivers without problems. Have imported a simple 3 midi track song using VSTi for sounds into 5.1 and there is no sound but the tracks section shows midi activity on all tracks but the transport bar shows nothing. Went into device setup and changed the Asio4all driver to Asio DirectX full Duplex and it now plays with sound, but now the input latency is around 300ms so its unuseable except for playback. Anyone have any ideas on this, i cant find anything to suggest the ASIO4all shouldnt work with 5.1. The second problem might be to do with the first one, there is a big drop in volume levels using 5.1 compared to SX3 playing the same file, using the transport volume slider on full its still barely acceptable. If i play the song in SX3 shut it down and open 5.1 its like half the volume even though nothing has been altered. The only way to achieve the same volume is by raising the pc speaker volume to nearly max. I have never had volume probs with SX3 or any other version, far from it in fact i'm always turning levels and volumes down just 5.1 Any clues thanks for any help you can offer
