Just got a Soundlink Mini II- using on HP Pavilion Windows 10 laptop:
pairs well and works well with Bluetooth, but went to use AUX input form the laptop output and get an audio hum.....hum is there if on charging pad or if charging cable is plugged in the speaker, but NOT when running off battery. Checked various audio settings on PC and hum is not instantaneous when plugging in but after a second or two. Any ideas?
Thank you for your post and welcome to the Bose Community.
I'm sorry that you are experiencing this humming noise whilst your SoundLink Mini II is charging and connected to your PC via AUX. As this is only experienced during this time, It sounds like this is due to grounding.
I'd recommend ensuring that your source volume is at maximum and then adjust the speaker volume to your preference.
I'd also like to welcome other members of the Community to input their suggestions.
