I followed the instruction on https://randomblog.hu/using-your-android-phone-as-a-webcam-for-ubuntu-20-04-with-droidcam/ to download the droidcam to a directory on my Ubunto PC. I ran the following commands in succession:
sudo ./install-client
sudo ./install-dkms
sudo ./install-video
On the second command sudo ./install-dkms, I got the error ./install-dkms: line 32: dkms: command not found. I still proceeded with the third command, install-video.
The DroidCam installed and I installed the DroidCam app on my Android phone. I entered the IP on the DroidCam on my Ubuntu desktop. I was able to make a test video call. The video was displaying but the audio on the microphone was not working. How do I get the microphone to work?
