Other Parts Discussed in Thread: TLV320AIC3254EVM-K

I'm working on windows 7. The AudioEVM driver is drived.

I run the adaptive filtering demo. The audio is not out from the headphone. I also try the 5074.Script and beep script. All of them are no audio too.

What should I do?

Hi, Zhou,

First of all you need to ensure that the TLV320AIC3254EVM-K is being recognized by the Codec control software (the GUI USB LED must be marked as green). Then, you should ensure that the EVM is selected as the default playback device. Please verify on the Sound options that the EVM is being used to play audio.

Please let me know if you have more questions or comments.

Best regards,

Thanks for your interested. I found the problems is that the motherboard's SW2 was selected at wrong position. Seems like that the datasheet and software information's description cause the problems.
