I must admit, that this is first problem after approx. 13 years, I own the cards.
Weird things happened, Sometimes I have to reboot the system several times, so that I get the outputs playing, and when the system plays with no problems, after I add the in or output buss, outputs stops playing without any visual aware and then I remove the input busses and after approx. 3 removals, system start working and playing output busses without problems. I try to change the buffer , without any success. Can you help me to solve the problem. I use the latest drivers and firmware from your webpage. Can you, please help me, thanks a lot, Janez
