Even I m facing the same problem. The audio recording device option cannot be changed and the tab is grey and clicking doesnt affect it. I cant set out the wave out mix. I tried the preferences and the 2 audio recording device options available are : a. Microsoft sound mapper - Input b. Microphone (realtek) There is no "wave out mix."
Since Microsoft intentionally removes the Stereo Mix / Waveout Mix option from its drivers, you need to try to download the latest version of the sound card driver and install it. If you have an onboard sound card, go to the support section of the manufacturer of your PC (such as Dell/HP/Toshiba/Sony/Fujitsu/Lenovo/Acer) and download an audio driver for your model of the PC that works with your Windows version. Please note that the manufacturer doesn't support Windows 7, you can try to use Windows Vista driver, althouth there is no guarantee that it will work and will not damage your hardware. If you can't find a driver, you need to know the sound card that your PC has. Then you can go to the web-site of RealTek, Sigmatel, Creative,... and download a driver for your particular model that works on Windows 7/XP/Vista/.... If the driver has an installer, you can easily install it. If the driver doesn't come with an installer, unpack it and: 1. Open "Control Panel". 2. Open "System". 3. On the left side under Tasks click on the "Device Manager". 4. Scroll down to "Sound, video and game controller" 5. Open that and you will see "High definition audio" 6. Right click and select "Update driver software" 7. In the new window choose "Browse my computer" and "Let me pick..." 8. Uncheck the "Show compatible hardware" box 9. Click "Have disk" 10. Browse to the location that you extracted your driver files to and just keep opening the Vista folder until you get to a bunch of .INF files. Don't select any of those just have that open. Your computer should have the one it needs in the file name box. Just click open and then "OK". 11. The window should open with a list of drivers. Choose your one and hit "Next" to install it.
why the hell can’t I set “Wave Out Mix” as the audio recording device??? I haven’t change anything and the program doesn’t let me change audio recording device. The tab is gray and doesn’t effect clicking on it.
it keeps saying Error please check the input device settings and project sample rate... what do i do to fix that
Great opensource software if you learn how to use it. Even better if you add the plug in packs found on the Audacity forums
