    I tried to install the system sound driver I guess its called Parallels loopback, but it says that that is currently not possible and I should try later. Does anybody know what might be the problem? I also tried to reinstall Toolbox but with no luck. I am using macOS Big Sur.

    Thanks for your support

    Hello,
    could you please attach screenshot?

    To correctly reinstall driver you have to:
    - Go to /Library/Audio/Plug-Ins/HAL/ folder and remove ParallelsToolboxAudio.driver folder. You should have admin rights to do it.
    - Restart your Mac
    - Launch Record Screen (or Record Area, Record Window) tool and choose 'Computer' value for 'Record audio from' option
    - Tools will ask you to install the driver and restart Mac again
    - Restart your Mac

    Did it help?

    I also have a related issue. I have Parallels Toolbox 2.0.4 on a Mac Pro and 4.1.0 on a MacBook Pro, both with Catalina 10.15.7. The issue is exactly the same on both. I was not able to get the audio when recording a zone and choosing either "Same as system" or "Plantronics headset" (the audio recording was always from the external mike). After choosing "System audio", I got the message that a driver had to be installed and I selected to do it. Then I was told installation was almost complete and I had to reboot, which I did. But nothing changed. I looked for the /Library/Audio/Plug-Ins/HAL/ folder (mentioned in this forum) and HAL was not there. I thus created HAL myself and this time the installation succeeded. So, clearly, the installer fails to check if HAL is present or not.

    Now I can record audio with zone recording, but I cannot change the volume of the sound I hear in my headset while recording (I can only turn it off or on). If while recording I select my headset as output instead of Parallels Loopback, I can adjust the volume, but during that time, audio recording is not done. If I then go back to Parallels Loopback, audio recording resumes, but I hear nothing in my headset. So the only way to use zone recording is to preset the sound level in the headset to a level that will hopefully be acceptable during all the recording.

    I suppose there is nothing I can do about that and that the only solution is to correct the bugs. But if there is something I can do, I'd like to know.

    Hello
    Yes, we know about the problem with changing sound level while audio is being recorded. We're working on it and hopefully fix it in one of nearest releases.

    I recently upgraded to macOS Big Sur, audio was not working with videos from the record window tool. I followed the steps above (deleting driver files, installing, restarting, etc.). Now the audio works when I view the recordings, but when using headphones through the audio port, no volume comes through when I'm recording the screen.

    So if I do not use my headphones and opt for using "Internal Speakers" as sound then the audio is recorded using the record window tool. If I select "computer" for "Record audio from" (sound output is Parallels Loopback), then the audio does not record. For context, I am recording a webex video.

    Hello
    Do you have same issue while recording other video (from youtube, e.g.)? Or the problem is with webex only?

    Thanks for replying. It seems that the audio issue is only with Cisco Webex Training. The window and screen recording audio works with Webex Meeting.

    Thanks for info. Yes, we currently have problems with recording of WebEx meetings/videos and continue to work on this issue.
