Mpv media player?

@Ben

Stereo Duplex gives me stereo through Front and Rear speakers

A Duplex audio profile is for audio playback and capture

Analog Stereo Duplex = analog-stereo-output + analog-stereo-input

@Edward78

when I play a new vid. each time I have to select my audio device

Archwiki - mpv - Specify an audio output

Run the following command to get a list of available audio output devices

mpv --audio-device=help

Then add one to ~/.config/mpv/mpv.conf. For example:
audio-device=alsa/hdmi:CARD=NVidia,DEV=1

but you would probably want to select a pulse or pipewire output rather than alsa, so it does not take exclusive control of audio playback device, or fail to play audio if device is already connected to PulseAudio or PipeWire
