Hello, I am also having the same problem with the Teralink-X1. It works fine on Windows Vista and XP Professional. It does not work on Windows 7 (I have no sound). Some things I noticed...
1. The power light on the Teralink is on.
2. Both Windows and foobar 2000 recognize/detect the Teralink X-1 and I am able to select the Teralink-X1 in the device manager menus.
3. My Bel Canto DAC has a green indication light when it is receiving a signal, but that light is red when hooked up to my Win 7 computer.
4. My computer automatically searches for drivers for the Teralink; it says I have the lastest drivers.
@JulioCat2: I have not tried the Polytech Asio driver. Could you perhaps provide a reliable link where I can download it? Thank you.
@Schoenburg: I realize this thread is over half a year old... have you fixed the problem yet? If not, hopefully we can figure it out...
Any input or suggestions would be greatly appreciated, thanks
