Can not record via SPDIF interface

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Configure driver 
2. Try to set sound defaults
3. Output works, Input can not set default.

What is the expected output? What do you see instead?
I can not set the card as the default recording device. I can not choose 
the interface in recording software - using nero. 

What version of the product are you using? On what operating system?
1.8 on Vista

Please provide any additional information below.
Output on SPDIF works fine, it is the default device for output. I have 
tried turning SPDIF output off (I think I read to try that somewhere).

Have you tried turning on the SPDIF-In recording in the control panel applet 
(cmicontrol.exe) ?

Yes, I turn that setting on. I am not sure about the other settings for the 
SPDIF-In 
so they are still unchecked. My first goal was to be able to select the 
SPDIF-In 
from the recording software. My clue that there is an issue or an  installed / 
configuration problem is that I can not set the SPDIF-In as the default 
recording 
device. Setting the output device as the default works fine after going to 
device 
manager and removing the sound card, then doing a scan for new hardware (maybe 
a 
reboot would have worked as well). Sorry for the missing information in my 
original 
post. Thanks for any assistance.

Oddly enough, I can't set the SPDIF-in as the default recording device either, 
but I 
can select the SPDIF Interface as recording device and recording works. I've 
used a 
stone-old version of CoolEdit for testing: http://cmediadrivers.googlepages.com/

What recording software do you use?

I am using Nero - WaveEditor. I noticed in your image that your recording 
device is
Microphone. When I look at my recording devices in Windows, I have Microphone, 
Line,
SPDIF Interface all from CMI8738 . WaveEditor will not list any of those 
devices, it
just has Master Volume. Once I get WaveEditor or another package to see the
individual recording inputs, which one should I choose to get the audio? Is it 
ok if
I can't choose SPDIF in? Will choosing the Microphone or Line give me the audio 
from
SPDIF?

after fiddling around a bit, I've managed to get it working. I've used a 
freshly 
installed non-WaveRT version. Oddly enough, the audio system of vista plays 
hide and 
seek with the SPDIF interface for some reason.
It shouldn't matter whether you select the spdif interface or not for recording 
in 
theory, but I haven't actually bothered to test it yet.

Using Trust sc5250 with XP Pro in all digital setup. The dogber drivers work 
fine on
play from PC eg WMP using external DAC but I can't record using spdif in. Both
Goldwave and the XP recorder stop very quickly, 0.01 secs. 
Also, it it possible to use the card to pass a digital stream (from say a CD 
player
or DAB tuner) by routing through the card using spdif in and spdif out?

Further...I have got loop through to work but only through the coax to coax 
route.
Optical route does not loop through although optical out works fine. Still, I 
can't
yet record.

Just an update on the original issue. I continued to try different scenarios 
for the
driver configuration and fresh installs, but unfortunately I never got the 
recording
working.

dsisk112, I took another deep look into the code and came to the conclusion 
that you 
either have some hardware revision which is different to the cards I've tested 
against, or that your SPDIF signal can't be received by the CMI chip due to 
whatever 
reason. So, what vendor had your cmedia card produced, and what's the exact 
model 
number?

john, I've tested this card and it worked fine. The symptoms you're 
experiencing 
suggest that the card can't synchronize on the SPDIF-In signal to the effect 
that 
the interrupt isn't fired which tells the driver to copy the sound buffer.

should be fixed in 1.2.4, hence closed for now.
