Today, my iFi experienced the exact same thing. but I always left my iFi muted whenever I is not in use. As I played with the volume knob, only left speaker working, or right speaker working or only the sub working.
Worst yet, when I plug in an iPod on top of it, the volume went 100% with high pitch!
Please help, is there any spare parts I could order to solve this problem? I honestly love my iFi a lot.
