After waking up from suspend mode when I play music or a video, the system changed playing sound at my monitor speakers, detected as „card 2: NVidia [HDA NVidia], device 7: HDMI 1 [HDMI 1]“. Here is the full list: $ LANG=C aplay -l **** List of PLAYBACK Hardware Devices **** card 0: PCH [HDA Intel PCH], device 0: ALC892 Analog [ALC892 Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: PCH [HDA Intel PCH], device 1: ALC892 Digital [ALC892 Digital] Subdevices: 1/1 Subdevice #0: subdevice #0 card 2: NVidia [HDA NVidia], device 3: HDMI 0 [HDMI 0] Subdevices: 1/1 Subdevice #0: subdevice #0 card 2: NVidia [HDA NVidia], device 7: HDMI 1 [HDMI 1] Subdevices: 1/1 Subdevice #0: subdevice #0 card 2: NVidia [HDA NVidia], device 8: HDMI 2 [HDMI 2] Subdevices: 1/1 Subdevice #0: subdevice #0 card 2: NVidia [HDA NVidia], device 9: HDMI 3 [HDMI 3] Subdevices: 1/1 Subdevice #0: subdevice #0 I can only choose the HDMI device in gnome-control-center or pavucontrol. The other devices are gone, why what ever. When I restart the pulseaudio process, all devices will come back: $ sudo killall -9 pulseaudio # (many times, because pa restarts itself) $ /usr/bin/pulseaudio --daemonize=no --log-target=journal ^Z [1]+ Angehalten /usr/bin/pulseaudio --daemonize=no --log-target=journal $ bg 1 This behavior is new in 20.04. Before I establish the behavior of pulseaudio, I logged off and on again and all devices are shown.
