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?
