I’ve been using Audacity without issues on my PC running Windows 7 Ultimate 64-bit, but recently upgraded to Windows 8 Pro 64-bit and now I am unable to record from Line In or Stereo Mix. Playback using stereo mix works fine through the computers speakers, the input source sounds fine this way. But when I record in Audacity, I just get this buzzing noise (quite loud) which I can vary by adjusting the volume on the Sony digital recorder. When trying different settings, I either get the buzzing sound or no activity at all (meters are flatlined). Setup is as follows:
Audacity 2.0.2 (reinstalled)
VIA HD Audio (Drivers: VIA_Audio_V6016699_Win8)
Input from Sony ICD digital recorder (meeting recordings, human speech)
I’ve tried all combinations of the following settings:
Audio Host: MME / Direct Sound
Output Device (shouldn’t matter?): Speakers (VIA High Definition Audio) /or/ Microsoft Sound Mapper
Input Device: Stereo Mix (VIA High Definition Audio) /or/ Line In (VIA High Definition Audio) /or/ Microsoft Sound Mapper
Input Channels: Mono /or/ Stereo
I took care to match the sample rate and bit depth (44.1 / 16) in the VIA settings and Audacity. I cannot figure this out. Nothing has changed with the hardware, just the operating system. This also happens using the default drivers provided with Windows 8, I downloaded the VIA drivers after experiencing this issue.
Thanks in advance for any suggestions!
