TAS3251EVM: I2S connection problem with the TAS3251EVM

Part Number: TAS3251EVM
Other Parts Discussed in Thread: TAS3251

Hi,

I have two TAS3251EVM boards, both with the same connection problem. I have installed the TIAudDriver.exe and the device is listed in the device manager as "TI USB Audio UAC2.0". I can also set it as a soundcard with 48000Hz, 16-bit. When I hot plug it in, the Pure Path 3 SW tells me at the bottom "Successfully executed divider skript" and the light goes from red to green.

BUT, if I want to do the System Checks the "I2C Error: Error communicating with device. Please make sure EVM is connected." It seems that I2C is not working. I tried two different EVMs.

Any ideas? System is a Lenovo Thinkpad 64bit with Windows 10 Enterprise.

BR,

Kilian
