Start it, go to the configuration tab, and select "OFF" for your HDMI outputs and turn on the appropriate analog outputs for your speakers. Note that pulseaudio is fond of seeing an HDMI connection turn off and on (i.e. the monitor turns off and on) as a request to make that HDMI output the new active one. -dsr-

If so, I would guess that you have something claiming them already - pulseaudio or jack or pipewire. Check for running processes. -dsr-

Now try speaker-test -C2 -Dhw:Generic speaker-test -C2 -Dfront:Generic and so on to see if you get output that way. Also check the mixing levels with alsamixer; accidental muting happens. -dsr-
