Hi certs12, The hardware loopback only works on the analog portion of the codec. Meaning the mic/line in to the speakers/headphone. Not on the S/PDIF or HDMI. You can try the listen to feature, but it will have latency since it is done in software. There isn't a way around that. Thanks, Chris

My system is not a dell, and uses viahduaa.sys V6.00.0001.7300 as the sound driver.
