My setup is the following: I have a PC and a tablet (Nexus 7), and only one sound system (2.1, 3.5mm input). My goal is to play both sounds coming from my PC and from my Nexus 7 whilst it is in the (official) docking station through the speaker-system hooked up to my PC.
I've looked for a way to merge the two incoming signals but without any success (except for cost-heavy DJ equipment to mix both signals), so now I'm wondering if it's possible to simply re-route all outgoind audio via USB to my PC (both running Windows and Linux (Ubuntu)).
I'd appreciate any help you guys can give me. Thank you.
