Hiya sounds alot like there is a power supply issue with the unit that will require repair for it to be doing off or on. Probably wont be to expensive, request a quote first to make sure viable.
Best of luck

Run 2 RCA cables from the two Purple connections on your Receiver (Labled "PRE OUT SUBWOOFER") to the Red and White connectors on the back of your Sub (it does not matter which Purple connecter you plug into either the Red and White)
Set the volume control on the Sub to about 75%, and keep the power switch in the "ON AUTO" position. To set the Low Pass value, look at the back of one of the front speakers in your setup, and note its frequency range (will look something like 100Hz - 17kHz). Set the Low Pass at a value slightly higher than the low value on the back of your surround speakers.
To set the phase switch, stand in the middle of the room with some music on (something with some bass, but not over the top bass) and have someone switch between 0 Deg and 180 Deg. Listen for which setting sounds "Louder and Fuller". This is the one you want. You will need to do this each time you move the Sub, as its position may change its phase in relation to the rest of your system.

Humming noise on your sound is not due to your speaker but it is come from the amplifier.
I've encountered a lot of this problem that is caused by the electrolytic capacitor.
If you are a technician first locate for a dry joints on the board and then resolder it using your soldering iron and a high quality soldering lead. Resolder not only the capacitor but also around the output I.C.
If nothing happen then it is coming from your output I.C. sometimes it was leaky/shorted which produces a humming noise but first do the the above mentioned instructions before isolating the defective output i.c.

Have you looked at the manual?
The NEW thing doesn't work.
Does the subwoofer work for setup? That would certify the hardware and speaker definitions are ok.
The PC has the responsibility for defining and sending out something between headphone and full-blown 7.1 though the HDMI. Check your PC sound controls and the "Information on HDMI" section of the manual.
For the radio mode, probably the only analog stereo source you have, read up on the STRAIGHT decoding mode and Sound Field programs.

Disconnect the input(s) and see if it hums in the absence of an audio source. A bad audio cable shield or unwisely-routed audio cables will allow entrance of unwanted signals from external power sources, magnetic fields, even dimmer-controlled track lights. Sometimes, simply reversing the orientation of the ac power plug can eliminate humming.
