Without involving a TV! My Soundbar has an HDMI aRC

Windows 11

Just plug in HDMI.
Route the sound to HDMI in Win 11. You will get sound.
I dunno where the display image will go though. But you can duplicate the screen image I believe

 

Not working. Not even the Soundbar Getting detected.

Check your HDMI cable

 

Can you check if your Laptop HDMI output works with a TV?

 

Is the soundbar ARC only? If so, then the source needs to transmit the audio via ARC.

 

Have you used the remote control to select HDMI(ARC) as the input mode?
Does Windows 11 support that mode?

Not just the OS, the hardware itself needs to support ARC. ARC on laptops is not as common as ARC on display panels (tv).

 

I think ARC audio is for going the reverse direction from a TV that receives an over-the-air or streaming signal to the sound system.
Audio from an HDMI source goes from the source to the sound system as part of the HDMI video signal.

Does not the laptop act as an HDMI video/audio source?

 

Cable is fine
