Problem:

I am playing AC-3 or surround sound data from a software

application on my computer, sending the data from Audiophile USB S/PDIF
Out to my home theater’s AC-3 decoder. However, the decoder does not
recognize the signal and therefore refuses to put out any audio.

Possible Cause:

There is a bit within the S/PDIF digital audio stream that

defines the S/PDIF content as audio or non-audio. Most AC-3 surround
sound decoders expect this setting to be non-audio and will otherwise
reject the information. Go to the S/PDIF page of the Audiophile USB
Control Panel, select Consumer and Advanced Settings, and then select
“DD/DTS Pass-Thru.”

• Problem:

I have Windows 98SE and I want to install the Audiophile USB,

why do I need the original operating system CD-ROM to install your drivers?

• Answer:

Windows 98SE does not have the system files to support USB

Audio installed as part of the core installation. Instead these files must be
added.The necessary files are located on the Windows 98SE CD. If you do
not have your original Windows 98SE CD, contact Microsoft Technical
about how to acquire the files for USB Audio support in Windows 98SE.
