As Lennart said, you can actually use > pavucontrol to move the loopback stream wherever you want to. I didn't understand how to do this, but this has a minor importance, I definitevely want that the tv audio goes trough the standard output, just that. > > > Anyway with this command > > > > pactl load-module module-loopback > > source=alsa_input.pci-0000_01_08.0.analog-stereo > > sink=alsa_output.pci-0000_00_07.0.analog-stereo rate=32000 format=s16le > > > > I can ear the tv audio from the standard output.
