Kulp Show Player FM Transmitter Problems

[moparjer]

Hooked up brand new Kulp Show Player, brand new Sound Blaster 3 and brand new Signstek FM Transmitter 2 nights ago. All was well until last night. Now, the FM transmitter hums and statics through my car radio and home stereo. Been trying to trace this. Kulp Show Player w/Sound Blaster plays through $1 (no kidding) earbuds I bought at Dollar General tonight. I also get music through the Show Player 3.5mm jack. However, it won't play through my car or home stereo. I then bought a new aux cable (not at Dollar General). Still nothing through a radio with either the Sound Blaster USB connection or the 3.5mm Show Player Pi jack. I then hooked the Sound Blaster and FM transmitter to my laptop USB. It transmits Amazon music through the FM transmitter to my car perfectly. I have FPP audio set to Sound Blaster 3---Speaker---Default video output device is set to HDMI. Should it be disabled? Any help will be appreciated.

What changed last night?

What is the FPP volume set to?

How close in inches is controller, sound blaster and transmitter?

Did you try powering the sound blaster using powered hub?

Are you getting generated static (like the transmitter is working but noisy) or general background static?

I watched the xessentials audio video and followed the directions. Everything works perfectly again.
