You could have done a very slow damage to the Yamaha if your UPS was not a pure sine wave type ( on line UPS ). Most of the UPS we get are called Off line type and are far cheaper than the On line pure sine wave type. The out put of the Off line type UPS is not a sine wave ( the natural waveform of AC voltage ) and strains the Power supply circuit of any device connected to it.
Now if the humming sound is the same irrespective of the volume position, it is a power supply problem. You might be having a leaky rectifier diode or capacitor. First change the diodes and see if its ok then change the main filter capacitors too.
