Just Sharing here-
My almond+ sits next to my computer speakers (creative 2.1 set) and the speakers had a pretty audible hum produced out of the speakers since installing the router. After troubleshooting several ideas (ferrite beads, using different power outlets, speaker wire routing) it was determined the proximity of the almond+ to the speaker subwoofer (which also has inputs for speaker, AC power, and the speaker volume controller) was causing the humming. The subwoofer had to be moved at least around 3 feet away from the almond+ to prevent the speaker hum.
I'm assuming this is an RF susceptibility / AF coupling issue in my speakers caused by the almond+ emissions. Hopefully this information could prevent others from having the same issue. I do not believe there is anything wrong with the almond, but that my speakers could use additional protection.
My wireless configuration is dual band with 2.4 using Ch11 @29 dBm and 5GHz using Ch48 in 11ACVHT80 mode @31dBm (max power for both radios).
