My speaker " Philips SPA5300 " is constantly producing humming like sound which is really annoying, why is this happening?
Speaker producing constant humming sound !!
> Is that happening when used with PC or with other portable device?
If it's happening in PC:
> It's probably happening only when plugged in front 3.5 mm jack.
> Is any other device (like any USB device) also plugged in front USB port while the headphone is plugged in?
> Does the hum noise disappear when no other device is plugged in?
