For some reason, awhile back, I used to be able to record with Stereo Mix on Audacity, Hypercam, even to other people on Skype. But all of a sudden, out of nowhere, it just stopped working. There was a time where it said it was unavailable, but now it says it is working, but when I try to record sound using Stereo Mix, it either doesn't record the sound, or the program doesn't recognize that Stereo Mix exists.
I have "Realtek AC'97 Audio for VIA (R) Audio Controller" under my Stereo Mix properties (I'm guessing that's like the driver or audio device name). When I try to record in Audacity, I get a message saying "Error while opening sound device. Please check the input device settings and the project sample rate." The input device (the Realtek AC'97 I'm guessing) says it's "working", and the project sample rate is the exact same as it says in my recording settings. My guess is that Audacity doesn't see "Stereo Mix" or "Realtek AC'97" as a device currently on my computer, which doesn't make any sense, cuz my computer says otherwise. It also doesn't make sense, because I'm able to select "Stereo Mix" as a device for recording IN Audacity itself.
I've read other posts about this problem, and none seemed to be of any help (I've tried the solution posted but didn't fix it). Is it because my "Stereo Mix" isn't set up to my speakers or something? Is it because I have Realtek AC'97 and not the HD one? Could it have something to do with my current USB Microphone (which that seems to work just fine for recording)? I dunno, like I said, it "used" to work, but just suddenly, out of nowhere, didn't work anymore.
By the way, It is set as the default device, and is enabled and says it's "working". It also does not have any green bars next to it (or lack thereof), and in the properties, I do not see a "listen" tab.
