anyways to out my pc Sound to a bluetooth speaker with just wifi or my home network?

basically I am looking for an APP to transmit my sound to my speaker through wifi.
not straight bluetooth connection.

I know there has to go be a way without hardware or wires

I've seen home stereo receiver that support this but I'm oldschool i like my copper

Did you check the car audio sub?

Bluetooth and wifi are on different frequencies

Unless one device supports it both it won't work

There are many hacks and such but a notive will wind up with a fried sound card

just get a radio
