configuring usb audio device as spdif in XP

by benswis / December 2, 2009 7:15 PM PST

I have a USB to SPDIF converter that is supposed to support 5.1 surround.
I can hear stereo sound, but not 5.1 surround.
I know there are many free tools that enable passthrough on spdif so the receiver does the dedcoding instead of the PC.
However windows XP doesn't see the USB audio device as SPDIF
is there a way to configure the USB audio device as SPDIF without drivers?

That sounds proper.

Most MP3s I see are stereo and even on a 5.1 device and speakers you get "stereo."

Your post is light on the detail about the sound source file. If it is not 5.1 why would you expect 5.1? Do tell.

the sound source is not mp3

In reply to: That sounds proper.

the sound source is an AC3 or DTS file that is encoded with 5.1 surround information.
i found many apps that tell the PC to leave the decoding to the receiver if i had a normal SPDIF output from my soundcard (AC3filter for one), but all i can manage with the USB output is the "stereo" you speak of - taking 2 channels and hearing them on all 5 speakers

if the PC does the decoding the USB device can't output the 5.1 to the SPDIF properly because without encoding SPDIF supports only 2 channels

Still light on detail.

Since your posts are incomplete (remember this is a member to member discussion forum and not tech support) call the maker of this thing (you never told make, model) and ask for fix or refund.

Not everything works so the lesson is when it doesn't work and they can't fix it, get your money back.

Thanks and I probably will.

I just wanted to know if there is an easy way to make windows XP think the USB audio device is an SPDIF output

This is probably what the driver is supposed to do...

Thanks anyway,

Once in a while you hear the questions "Is there a GENERIC driver for _____?"

The answer is no.

I do know the GENERIC USB AUDIO DRIVER Microsoft put into XP is a simple thing with stereo only support so unless the maker has a driver then the product is not ready for you.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
