Hi, I can't change the clock source in my Hercules 16/12FW to "SPDIF Coaxial". Every time I try to do this in the Hercules control panel, it just switches back immediately to "Internal". Also, I've noticed that while my GT-6 (digital guitar effects processor) is connected to Hercules, all the other selections in the control panel seem to be functioning really weirdly. For example, if I change some channel's balanced / unbalanced selection, the selections (-10 dBV, +4 dBu etc) are changing by themselves. It's like some process would be updating the console all the time (the selections are "blinking" constantly) This stuff only happens while the gt6 is connected. The analog inputs seem to be working fine. I'm using my gt6 every day with another computer with Terratec DMX 6Fire and it's working perfectly. I've got the latest drivers for Hercules, using Windows XP SP2. Please, can anyone help me with this???
