XDG_RUNTIME_DIR (/run/user/1000) is not owned by us (uid 0), but by uid 1000! (This could e.g. happen if you try to connect to a non-root PulseAudio as a root user, over the native protocol. Don't do that.) **** List of PLAYBACK Hardware Devices **** card 0: sofhdadsp [sof-hda-dsp], device 0: HDA Analog (*) [] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: sofhdadsp [sof-hda-dsp], device 1: HDA Digital (*) [] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: sofhdadsp [sof-hda-dsp], device 3: HDMI1 (*) [] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: sofhdadsp [sof-hda-dsp], device 4: HDMI2 (*) [] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: sofhdadsp [sof-hda-dsp], device 5: HDMI3 (*) [] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: Loopback [Loopback], device 0: Loopback PCM [Loopback PCM] Subdevices: 8/8 Subdevice #0: subdevice #0 Subdevice #1: subdevice #1 Subdevice #2: subdevice #2 Subdevice #3: subdevice #3 Subdevice #4: subdevice #4 Subdevice #5: subdevice #5 Subdevice #6: subdevice #6 Subdevice #7: subdevice #7 card 1: Loopback [Loopback], device 1: Loopback PCM [Loopback PCM] Subdevices: 8/8 Subdevice #0: subdevice #0 Subdevice #1: subdevice #1 Subdevice #2: subdevice #2 Subdevice #3: subdevice #3 Subdevice #4: subdevice #4 Subdevice #5: subdevice #5 Subdevice #6: subdevice #6 Subdevice #7: subdevice #7
