I'm trying to record the audio output of my pi but i can't find any good solution.

I tried to use arecord but it fails because I don't have any input devices. Because of this my idea was to redirect the sound of the output to a virtual audio input card.

Is this idea possible? If so, will I still hear the sound on my speakers? If this is not working, do you have another idea how I could do it?

  • Try modprobe snd-aloop. – CL. Dec 20 '14 at 8:25
  • thanks, this creats a new device in alsamixer "loopback". but alsamixer tells me that "This device does not have any controls". arecord keeps saying: "arecord: main:682: audio open error: No such file or directory" any idea how to fix it? – airi Dec 20 '14 at 11:22
  • You have to use the correct parameters for arecord. But the aloop device will not play anything to your real output; maybe you should PulseAudio. – CL. Dec 20 '14 at 19:38
  • It's probably not Pi specific. Maybe U&L.SE would be of better help. – Ghanima Nov 29 '15 at 2:14
