  2. Stereo mix showing but not showing audio

    A potential solution for those who use digital outputs to a separate sound system for your sounds (rather than speakers or headphones), and have tried all the normal suggestions when Stereo Mix shows up on the recording tab, but shows no audio, and programs
    such as Audacity won't record a signal.

    I use digital optical out from my sound card (Realtek High Definition Audio) to my sound system. There are therefore no speakers connected, and no speakers show in the sound settings. And no audio showing in Stereo Mix.

    However, connecting headphones instantly solves the problem - stereo mix shows audio, programs like Audacity can record again (plugging headphones in the headphones jack makes no difference to the digital optical output signal = does not mute it).

    I would be really interested to know why Stereo Mix will not show audio if there are no speakers or headphones connected.

    Stereo Mix

    Hi. I have a dell computer. When I try to record audio output using, say, audacity, using stereo mix, it records an overly loud background noise, which isn't present (or at least must be greatly exaggerated) in the original. I have the same issue if I instead
    use Microsoft powerpoint's screen recorder to record audio from a browser.

    However, if I do the same with windows game screen recorder, there is no issue - the recorded audio sounds just like what I hear.

    What's going on with the stereo mix?? How can I configure it to not have this background noise (which must be possible because it is not present on the windows game recorder)?

    Both windows game recorder and audacity are using stereo mix, and I can see no discernible difference in the way they are capturing the audio - but there must be one since I can hear it.

    Interestingly, if I turn the stereo mix level down to zero and now record (using stereo mix) on audacity, it still records the audio at nonzero volume (albeit faint),
    together with the background noise. Is this supposed to happen?

    Thanks for your replies.

    Can't record Stereo mix (Desktop Audio)

    Stereo mix for mic audio or something else - help please

    Hi, you can't simply download it. It's a question of whether your hardware and audio driver now support it or not.

    One thought was:
    - back in 2007
    Stereo Re-mix thread (was T61/p Sound Recording?) - Thinkpads Forum

    There are articles with a range of supposed 'fixes' but if your PC simply does not suport it, well, that's tough.
    E.g.
    How to Restore Missing Stereo Mix on Windows 10 - Appuals.com

    Note how this refers to using a much older audio driver:
    How to Enable “Stereo Mix” in Windows and Record Audio from Your PC

    Then there's this program (not free) that claims to make it available (which you can download!):
    Stereo Mix Plus - Fix no Stereo Mix on Windows 7/8/10/Vista | Stereo Mix recorder/enhance tool

    I seem to recall some have said this free program can help (Virtual Cable):
    How to Record Your PC’s Audio With Virtual Audio Cable

    And if you find no other way, then see:
    How To Fix Missing Stereo Mix Or Wave Out Option On Windows
