[SOLVED] Are 2.5mm front speakers & bluetooth rear speakers possible?

[mozga628]

This Christmas for my daughter i purchased a GTRacing gaming chair for her computer. The chair comes with integrated speakers that connect via a Bluetooth receiver. https://www.gtracingchair.com/products/music-series-gt890mf-red

i can't get the front speakers (connected via 2.5mm port on the mainboard) working at the same time with the chair's Bluetooth speakers (identified in Windows as headphones) as rear speakers.
i purchased this bluetooth transmitter: https://www.amazon.com/Plugable-Blu...d_r=GARDVVBPPZ1BDSRA8WPS&psc=1&qid=1577663249

I can get either to work normally on its own (configured as front speakers), but no joy in creating a 4 channel "quadraphonic" (term used by windows) sound setting.

Please help me fulfill a promise to my 14yo daughter!

You need something like this - https://www.amazon.com/TaoTronics-Bluetooth-Transmitter-Receiver-Simultaneously/dp/B01EHSX28M/
And this - https://www.amazon.com/Wideskall-Plated-Stereo-Splitter-Adapter/dp/B01CRXGEDY/
And this - https://www.amazon.com/Headphone-Earpiece-Adapter-Cordless-Panasonic/dp/B07SP8TNCZ/

You'll plug the 2.5mm splitter into the computer (are you sure it's 2.5mm?). Then plug the 2.5 to 3.5 adapter in. Then plug the Bluetooth transmitter in (and the standard front speakers). Then link up the chair to that transmitter. 😉
