When the digital audio source changes sample rates, or I select aSymptom:different digital input using the Format button, the audio is muted for a short period of time. This is normal as it takes a small amount of time for a digital audioSolution:receiver to lock onto a digital audio source. In order to prevent spurious noise, the Super DAC mutes its analog outputs until it sees a valid digital signal for 200 milliseconds.

When applying a digital signal to the Super DAC, the DAC's "DataSymptom:Valid" LED lights erratically or not at all.

The digital signal being input may be invalid or the digital cableSo ution:may be faulty.

Valid digital data is coming into the Super DAC (the D/A ValidSymptom:LED is lit), but there is no audible analog audio output.

Check your analog output connections from the Super DAC. Solution 1: The digital data source may be sending valid data, but the data couldSolutionbe static2: (non-changing or DC). Verify that digital source material is actually valid. The digital data source may be sending valid data, but the data couldSo utionrepresent3: an extremely small waveform (one with very low volume) that you are unable to hear.
