I read through all the FAQs and posts but didn’t see anything like the problem I’m experiencing.
I have a SurfacePro 3 running Windows 10. I didn’t try recording in Audacity before I upgraded so I don’t know if the problem is Win10 or something else. My Audacity is 2.1.0.
I enabled the RealTek StereoMix as the default recording device and muted all other mic inputs. I’m trying to record a YouTube video (not copywrighted). When I have the Audio Host set to MME I get a flat line recording - no input. Recording Device is set to Stereo Mix (RealTek High Defi). The RealTek Stereo Mix Default Format (in Sound->Recording->Properties->Advanced) is set to 2 channel, 16 bit, 48000 Hz - the only other choice is 24 bit, 48000 Hz.
When I set the Audacity Audio Host to Windows WASAPI and hit record, I get the error message: “Error while opening the sound device. Please check the recording device settings and the project sample rate.” I set the Audacity->Edit->Preferences->Quality to match the 16 bit, 48000 Hz settings of the RealTek Stereo Mix. Still no love.
As an added item, the Recording and Playback meters in Audacity show variable green up to about 48 without any applications producing sounds on the computer. That might be just background noise but I’m not sure.
I haven’t tried updating the RealTek driver because, as near as I can determine, I have the latest at 184.108.40.20643. However, there is a cryptic comment in the Sound->Recording->Stereo Mix->Properties->Controller Information->Properties->Events->Information: “Device HDAUDIO\FUNC_01&VEN_10EC&DEV_0288&SUBSYS_10EC0191&REV_1000\4&dcc60be&0&0001 requires further installation.”
Any ideas on how I might fix this would be appreciated.
