I have a bluetooth device which is connected to my speakers. But I also have a cd player. I swapped the mini jack between the two, which was ok, but not optimal. So I bought a jack splitter.
Now, the bluetooth sound is fine (same as before) but the cd sound is very soft. If I remove the power source from the bluetooth device, the cd sound is as it was before
Why does this happen and how can I fix this?
