USB audio

Other Parts Discussed in Thread: PCM2704

Hi all,

My customer is planning to connect two USB DACs (like PCM270x series) to one PC.
One USB is for LEFT channel audio.
The other one is for RIGHT channel audio.
Is it possible to realize this method by use of a standard Windows driver?

Regards,
Toshi

    Hi Toshi, 

    It will depend on the operating PC.. but the standard in windows is to select and use only one sound card at the same time.. I guess it is then not possible to use one sound card for two USB port run them simultaneously.

    This is something to be verified from the PC system.  

    However as long as the I2S signal going to the two PCM2704 is the same in the same timing, the audio file will runs simultaneously through the both speaker Right and Left.

    Best regards,
