Ubuntu – Ubuntu 20.04 plays sound only through HDMI monitor


My ubuntu desktop does not play any sound through speakers, connected to sound card.
It always plays through HDMI monitor, like it is the only sound playing device connected.

I have these settings, and it still plays through HDMI monitor.

When I plug my headphones – the system sees it in the 'output device', but sound still goes through HDMI.

When I remove HDMI monitor (it is my secondary monitor), then the sound works fine.


cat /proc/asound/cards

 0 [PCH            ]: HDA-Intel - HDA Intel PCH
                      HDA Intel PCH at 0xdf220000 irq 126
 1 [NVidia         ]: HDA-Intel - HDA NVidia
                      HDA NVidia at 0xdf080000 irq 17

Can you help?
