Hi every one and thanx for your kindly attention,

I am in trouble with my audio session under SnowLeopard and AMD system:

AMD 64 X2 3800+, MoBo ASUS M3A-H SNOW LEO 10.6.5 FIREWIRE VT6306 S.CARD M-AUDIO PF LIGHTBRIDGE FIREWIRE BUSed.

All works as well except for my audio session: I cannot use no Logic version or Protools since they have same problem: randomly works for some minutes, then audio functions stops, my audio cards (profire lightbridge from M-AUDIO) start blinking on midi out led and audio became a triggering, like a switching on/off on the same sound as Apple OS crash or since I power off audio unit or reset the pc.

This occured on both Logic or PT under snow leopard. I have tried all kernels and boot loaders. Nothing to do. I have tried many SL distro. Nothing to do.

This issues isn't out with Leopard 10.5.x. Here all works fine.

The audio card is connected through firewire card (VIA VT 6306 chipset). The same card is on another hackintosh...an Intel P4.
I cannot understand why on an intel hackintosh under snow leopard all works as well woth same audio card and same firewire card.

Do you have suggestion?

Please help me. I drivin' crazy!

Many thanx in advance!
