Ubuntu 20.04, Gnome shell
On older Ubuntu releases (<= 19.10), all is working fine.
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.
