I have an Alexa Dot, and Alexa Spot. The problem I am having is exactly the same on both devices which is a slight hum. I am running about 100 feet of speaker wire out of the 3.5 jack on each device to send the audio to two separate receivers. I am getting a very slight hum from both devices, but enough of a hum to drive me crazy. Any hum is too much hum. I am told the audio outputs on both Alexa devices are speaker level which is the reason I am using un-shielded speaker wire to send the audio to each receiver. Is the hum I am hearing caused by the fact I am not using shielded wire, and if using shielded wire is not the solution to the problem any ideas what the solution might be? I even used a ground loop eliminator on the Alexa Dot, and it did not eliminate the hum.

Thanks;
