Hi Achim, Many thanks for your email! I've tried both your examples, but so far no luck. Here is what I get when I type pactl list | grep monitor Name: alsa_output.usb_device_d8c_c_noserial_if0_sound_card_0_alsa_playback_0.monitor I also installed gstreamer-tools. If I do: pacat -r -d alsa_output.usb_device_d8c_c_noserial_if0_sound_card_0_alsa_playback_0.monitor test.pcm I get: Too many arguments. What am I doing wrong here? Best regards and many thanks, Christian Achim F rase wrote: > pacat -r -d >
