Hello. I'm new here. But I need some help.
Sound suddenly stops working with my FF800.

Everything was working, but suddenly started happening this:
When I am playing something (this happens in SONAR, Cubase and JetAudio too) the sound just disappears and comes back after a few seconds.
Sometimes I have to restart the FF800 or even the computer to return to work.
I can not work because it happens all the time.
It seems that the sound stumbles, also in simple player like jetaudio or wmplayer.

*Some weeks ago, the sonar when this happened, the sound would not come again, the solution was to click the "RESET MIDI" which should be a button the PANIC sonar, even with only audio tracks
*Almost never a red light turns on. It stays turn off when this happens.

I've tried: changing the firewire pci card, format the pc with windows XP SP3 and also with Windows 7
My system:
AMD X4, 4GB DDR3 RAM, ASUS MB, FW VIA card
The FF800 firmware version 2.77 is the last and the driver tmb 3016

Thanks
