Speaker Audio on Debian

Does anyone know where the settings in Debian are to enable the speaker DAC and route audio using analog audio interface to the SPKR_OUT_P/SPKR_OUT_N pins instead of HDMI?

i guess you need to choose “speaker playback” in

Sound&Video-> PluseAudio Volume control-> Configuration->HiFi , OutputDevices->Speaker playback

This worked, thanks!
