I’m on Debian 10, running Audacity 2.2.2, and I believe it’s my distribution’s release. I’m a Linux newbie so that’s my best guess.
The problem: I have a USB mic plugged in and I’m trying to record using that as the input. It’s a cheap Jeemak PC20, but I know it works because I tried it on another computer running Windows 10.
Any time I try to record using that or the external webcam (also USB), Audacity freezes. The laptop’s onboard mic seems to work ok, but I need the better audio quality of the line-in mic.
Try disconnecting the webcam. Reboot the computer, then launch Audacity. Select the USB mic as your recording device in the Device Toolbar. Does that work?
Try installing “Gnome Sound Recorder” and see if the mic works with that.
(To set which mic to use, start recording and open the Audio Mixer. In the “Recording” tab, select the USB device.)
The version of GNOME Sound Recorder I have doesn’t seem to have that option. I went into Settings and told the system to use the USB mic and then tried Sound Recorder. No luck but at least it didn’t freeze like Audacity did.
Gnome Sound Recorder uses PulseAudio by default.
To change the device that it uses you need to select the device in the system “Audio Mixer” (AKA “PulseAudio Volume Control”).
An easy way to open PulseAudio Volume Control is from the command line:
pavucontrol
Start Gnome Sound Recorder recording, then
“F2” to open a command line and enter: pavucontrol
Then switch to the “Recording” tab and select the USB device as the recording device for Gnome Sound Recorder.
I’ve tried the mic on different USB ports, no change. I’ve tried the webcam on the same USB ports and that works fine.
I’ve also tried the mic on a Windows machine and it works there.
Note: If you are unable to use the microphone due to the version of your computer system or other issues, please contact JEEMAK directly and we will help you to solve the problem promptly.
