nVidia sound card

[anacortesdamp]

Does anyone have a computer with a sound card by nVidia?

I'm trying to record my old vinyl LP's onto CD. I can't get the input to recognise the signal as stereo. I'm beginning to think that the sound card's input has been fried. Unfortunately, I can't find any users' guide or troubleshooter documentation from nVidia's website. Their customer support is non-existent.

I have a very good stereo image to test the system with. It's a low altitude fly-by by a Spitfire. The stereo effect is so good, that when I play it on my main system, the dogs are at the window looking for an airplane. They follow the sound, too!

When I run this CD through various input methods (into the preamp to a headset or a stereo or playing the CD directly on the computer's CD drive), I get the directionality, but when I run it into the sound card's "line in" jack, my audio editing programs (both Audacity and Adobe Audition) see it as a monaural signal. I get a non-stereo effect where you can't tell where the Spitfire is.

Do any of you computer gurus have any ideas?

If the sound card input is toast, I might go for an audio pre-amp to USB unit (available for about $50) that my audio pre-amplifier will feed. It's a cheaper solution than a new sound card, particularly since I'm not a gamer. I would like to get a decent copy of my 60 or so LPs, so I can listen to them on systems that don't have "phono" level inputs (particularly in the car).

Frank, I don`t know the answer to your question, but I can point you in the direction of someone who will be able to help - guaranteed!!!!.
I have NEVER failed to get answers from this site.

Sorry, Jim - been a bit busy. I looked through that site but couldn't find anything about nVidia. I'll be posting to it in the next day or two. I posted to an nVidia newsgroup a couple of weeks ago but have had no replies.

I'm just about convinced that the input stage of my sound card is fried. I'm now looking at an analog-USB converter that will take the line-in signals and turn them into a USB input. There's one available from Amazon for $30 that has been well reviewed, which is a good bit cheaper than a new sound card.

Frank, Please let me know the results of your attempt with sysinternals. I`m totaly convinced (from previous experience) that someone will come up with the goods.

Jim:

I've had a couple of replies on the sysinternals newsgroup, but they suggested stuff I'd already checked out.

I got quite a surprise yesterday. Just messing about, for the first time I started the source recording before I turned the editing program (Audacity) on. The audio coming through the cheap speakers on the computer was in stereo. As soon as I turne Audacity on to record, it went to mono!

I went through the Audacity user guide, but couldn't find a reason. I Googled for an Audacity user group, found it and discovered there's a "Preferences" set-up page. At that page, you can tell the program what format the source material is in. The initial default is mono!

I changed it to "stereo" and now get two parallel waveforms which are different when the stereo effect gets strong.

I'm still not sure about the quality as the recording I was using is of airplane sounds, not music. Since I was working yesterday afternoon. I didn't get any further with my experiments, but it looks promising.

Frank, Thanks for the interesting update. Whatever did we do without those on-line news groups? I`ve lost track of the number of times they have extracted me from the mire.
Your reason for wanting this recording is of great interest to me as I am attempting to produce one with road sounds as background in the vehicle museum.
