I have new R-15PM’s for Christmas, but cannot get any sound whatsoever, the speakers don't produce any turn on noise and when I put my ears close to the speakers there is no hiss, however the led is working fine. I have a tried a turntable and have connected via blue tooth both connections have no sound.
The other problem is my Mac (10.13.6) cannot see or recognise the R-15PMs at all.
Any help would be much appreciated.
