what ever blue tooth device you got connected to it turn off the blue tooth on it or disconnect it from settings. also make sure the 3.5 jack is fully pushed in it should override the blue tooth and work like any normal speaker

that'll be the player you got connected to it. it don't have a memory so can't play the music faster or slower then the player :)

every time i connect to the usb with any connection lead it shuts the usb down i.e. overloading the usb. i was wondering if i could wire a usb lead straight to the board or will it still overload it? if you've not come across this issue before then let me know as i have 2, 1 with a broken usb connector and this one which looks fine but won't let me charge it??
