Have you reinstalled Windows since the last time you were able to access these controls? If so, you undoubtedly missed reinstalling some drivers. Look for the original media, or download the latest drivers from the manufacturer.
What I'm trying to do is transfer audio data over from cassette to my computer.
I bought the appropriate cable in order to hook up my tape deck to my computer. It's all hooked up correctly; I checked it several times. I even get good sound through my computer when I start playing the tape, which tells me it's coming through the sound card just fine. After having transfered the MP3 sound file to my hard drive, I hear nothing. Even though it shows the file has been transferred, kilobytes and all.
I thought I would check the sound card recording volume, and here's a screen shot of the Error message I get when I clicked both volume tabs on "Sound Playback" as well as "Sound Recording": http://home.earthlink.net/~tnfrijole/Sound%20Card.gif
I found what I thought was the appropriate page on Microsoft's web site, (http://support.microsoft.com/default.aspx?scid=kb;en-us;319095) followed the directions, jumped through the hoops, but got a message in DOS saying "Can't open this file", or something like that. I don't exactly remember because it's been a few days ago.
I don't know what else to do.
Operating System: Windows XP Home
