So even though the stereo mix actually works, there is no sound flowing through the device to record. I suspect the USB headphones act as sound card, and thus the sound travels directly to them instead. Unplugging them solved the problem!Ī thread on Superuser points towards an explanation: Stereo mix can only record audio that travels through the internal sound card. As soon as they were connected, no sound was recorded.

This is a headset that is connected to the computer via the USB-port. The second time though, I plugged in my mother’s headset instead. These are normal headphones with a classic stereo plug. The problem turned out to be this: When I set up the stereo mix I had used my own headphones. But this time the sound I recorded was just silent! Even though stereo mix was selected as input device and all other settings were the same, it no longer recorded anything. Fast forward to the next day, and I continue working with the computer. I got it working and was able to record the sound without problems. Stereo Mix is a virtual recording device that allows you to record all sound currently being played on the computer, sort of what-you-hear-is-what-you-get.

I was helping my mother setting up her computer to allow for recording audio through stereo mix. I want to share a problem that I stumbled on recently.
