96kHz Stereo with signal loss

[GoogleCodeExporter]

I am using  soundcard 5.1 Surround Sound Card SC-5250 / 514DX 5.1 Sound
Expert Optical  from Trust
(http://www.trust.com/products/product_detail.aspx?item=12950)

I am using Driver CMIDriver-1.2.3-bin-x86.zip on WIndows XP 32  bit

I connect the SPDIF optical digital audio out to my AC3/DTS receiver or
decoder (Pioneer) .
The driver works excellent expect one problem. I was listening to a
streaming tv channel my AC3/DTS decoder recognized the sound as a 96kHz
Stereo and I was very happy about the quality of the sound but suddenly it
started loosing some part of the signal and it became very frequent. But if
I switch of the 96kHz Stereo option in the driver the quality of the sound
is ordinary but there is no signal loss.

First, 88.2 kHz and 96 kHz sample rate aren't officially supported for the 8738 
chip 
by the vendor. I've just tried to poke around a bit and found that on most of 
the 
8738 hardware, these sample rates work reliably.
Second, you don't have a quality gain from upsampling material of lower sample 
rate. 
In other words, material which has been made available in either 44.1 kHz or 48 
kHz 
won't sound better when sampled up to 88.2 kHz or 96 kHz.
Third, have you tried to verify the signal loss with another player? An easy 
test 
setup is foobar2000 its upsampling DSP enabled.
