Works:

I'm trying to record video from my Logitech webcam and sound from the headset. I can record it without a problem from the terminal using the following logged in as "myuser":

/usr/bin/ffmpeg -y -video_size 320x240 -framerate 30 -f v4l2 -i $videoSource -f pulse -ac 2 -i $audioSource -t 00:00:$duration -vcodec h264 -strict -2 /var/www/html/tmp/temp.mp4 2>/var/www/html/log/ffmpeg.$currentDate.log

Doesn't work

But, if I try to run it through PHP exec() in my /var/www/html folder (this is owned by www-data) it still runs, but the audio is missing.

shell_exec("sudo -u myuser /usr/bin/ffmpeg -y -video_size 320x240 -framerate 30 -f v4l2 -i $videoSource -f pulse -ac 2 -i $audioSource -t 00:00:$duration -vcodec h264 -strict -2 /var/www/html/tmp/temp.mp4 2>/var/www/html/log/ffmpeg.$currentDate.log")

Even from the terminal, It doesn't record sound if I use the sudo -u myuser I already added the users to audio, pulse and pulse-access groups.

I have the same result if I switch pulse to alsa

Here is my log:
