Monitor audio to receiver question MSI 343 CQR

[famasfilms]

My desktop has display port to my MSI 343 ultrawide, dvi-HDMI to my LG monitor and HDMI to my denon amp that then feeds my LG oled. Windows is set audio device to the denon and I can use three screens and get Dolby Atmos etc

I also have a laptop connected to both monitors via usb C and HDMI, but not the amp

The Monitor shows up in windows as sound output option, presumably as it has a headphone jack. Is there a way I can connect it to the amp as well?

I thought maybe a HDMI splitter but the LG monitor is set to portrait mode, and the TV is set to 2160p, so presumably they need the same resolution

My desktop is mostly used as a movie player with madvr.l, HDR etc but it's an i5 6600, and the laptop is a legion 5 ryzen

If I could somehow use the laptop as the playback device with connection to the amp then that would be ideal.

The other way I guess would be to have the laptop hdmi port with a switch box and switching between the portrait monitor for work and the hdmi connection to receiver for movies?

Or would one of the spare HDMI ports from MSI monitor carry audio to the avr. So laptop > usb c > msi > receiver

You could run a toslink cable from the TV and run the optical out from that to the amp so you send the audio via HDMI to the TV and then the TV outputs via it's digital out to the amp (if it's got an HDMI input then the Denon is actually an AV amp by the sounds of it, so has a DAC) using this method you can take sound from anything connecting to the TV via HDMI and send it to the amp ...or if your laptop should by chance have an optical out itself, some actually have a combined TRS/TOSLINK connector you could actually use that to output directly to the amp aswell.

I don't have a modern AV amp myself so I can't try this, but, I would think the HDMI link between the TV and the Amp could just pass the audio signal through ....so just select the TV as the output device from the laptop and then make sure the amp is set to output sound from it and see what happens. Reason I can't speak to this with absolute certainty is because I use a separate DAC and traditional 2 channel amp so I send all my digital audio to the DAC either directly or in the case of a PC I have connected via HDMI to my LG CX and then via toslink from that to the DAC which then passes the analogue signal to my amp.
