pavucontrol (pulseaudio volume control) redirects audio as well
as controlling volume. 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.
