try to record from the monitor device of the output

pactl list | grep monitor
shows which monitor devices are available, e.g.
	Monitor Source: alsa_output.pci-0000_00_1b.0.analog-stereo.monitor

then record for the monitor using
parec -d alsa_output.pci-0000_00_1b.0.analog-stereo.monitor --file-format=wav > rec.wav
