To be honest I don't see the point in that hassle as of now: I record with mpv --record or ffmpeg, and audacity for the sound, and synchronize with CLAP! . Accurate down to a 1/30th of a second: well enough for my needs, and it's fun. Now I have archlinux (endeavoros), up to date. Last time I checked the issue was still there.

no audio in any video recorded by GUVCVIEW version 2.0.6, yet the microphone is indeed recognized and the sound volume bars shown

Hi, I have debian bullseye , and you see below the version of guvcview. I can record any video just fine, but whatever audio format I use it's to no avail : no audio record. Cheese and audacity manage, webcamoid not, nor guvcview. I use an external USB Microsoft camera, and an external Jack stereo microphone. It works for audacity. Please help. gcb@debian:~$ cat erreurs_guvcview GUVCVIEW: version 2.0.6 GUVCVIEW: (status) saving video to /home/gcb/my_video-5.mkv AUDIO: (portaudio) Aborting audio stream...
