How to get AUDIO forwarding to work... if it's possible?

Hi, so I will try to hopefully explain as best as I can.

These are my devices:

Windows PC -> Cable Headphone1 output
Linux Laptop -> BT Headphone2 output
Android Phone -> Phone speaker output

What I want to achieve:

Have audio from all devices output from Headphone1 on my PC without having to use physical or software mixer.

What I managed to get working but sux due to audio stutter or delay:

Have audio from all devices output from Headphone2

How?

Phone paired via BT to Windows PC, using app on Windows PC called Bluetooth Audio Receiver gives me the ability to listen to my phone audio via Headphone1 (does not work for Laptop)
Linux Laptop paired to my Windows PC as an audio device allows me to set the Laptop as a output audio device for the PC so I can listen to PC and thus to the Phone via Headphone2

BUT, this causes phone audio to stutter via Headphone2 and audio from PC has at least 500ms delay.

Wish there was a way to forward audio from Linux Laptop to Windows PC the same way as from Android Phone to PC.

Any clues?

A long, long, long time ago I used a program/app that would forward a Windows PC sound to an Android phone.

Sorry, that’s not really helpful.

With ffmpeg in windows, you can listen to a UDP stream using the ffplay command. you can set up a udp stream as an output in ffmpeg in Linux. I would set up a virtual sink that goes nowhere in pulseaudio or pipewire to set as your output device and have ffmpeg listen to that sink. There are lots of options in ffmpeg available to tweak latency and quality.

Will give that a try tommorrow. Thanks for suggestion I had no idea ffmpeg can do this

It’s very versatile and does a lot of things and I do like ffmpeg and use it a lot !

Too bad their AV1 and OPUS implementation is bad and even outdated for opus :( !

Maybe pipewire and the ROC protocol? I’m not sure if it can be used on windows. You will have to refer to their documentation to get anything working. On Arch the package is called pipewire-roc. On Android the app you will need is roc droid. I have used it from linux to android, but have never introduced windows into the mix.
