Why would my 3.5mm jack on my new Klipsch Blue-Tooth speaker (The one II) not be accepting input from my PC headphone jack? I confirmed the PC jack is working by trying headphones. I tried two different cables, the one that came with it, and a high grade one. I can only get sound from Blue Tooth, and suffer what I read about being- the noteworthy degradation of sound. Is there an impedance issue with these Klipsch speakers relative to headphone output jacks? Just trying to avoid sending it back under warranty. Thanks!
