I got the Bose Wave Radio IV for Christmas and when I play CDs or through a WaveCast on my iPhone with Bluetooth, the sound is ok. When I try playing my TCL ROKU tv through the radio using an aux cable, I don’t have any sound at all until I’m on 70 and can barely hear much of anything even maxed out at 99. I tried it through my turntable and am having similar issues. I had previously had a Bose soundbar that worked pretty well with my tv so I know it’s not an issue with my tv. I was really hoping to use this for my tv and turntable as I don’t really listen to CDs and radios but this sound is useless. I’m pretty disappointed in this $300 alarm clock. Any assistance would be greatly appreciated.
