Solved! It was my cell phone causing interference. Absolutely crazy! Had no idea. Before I left on vacation, AT&T just had 4G service for my Galaxy S3. I returned to find this crackle and after about 2 hours of troubleshooting and head-scratching, I noticed that my cell phone had LTE service... coincidence? NOPE! Turns out the LTE service causes about 5 seconds of interference with the speakers before I get a text/notification. Kinda sucks now I have to keep my phone away from my workstation. It'll cause the problem within about 3 feet of the speakers. hope this helps anybody who has this same problem :)
[SOLVED] S-DJ05 Crackle after returning from vacation
Quite a frustrating issue I'm troubleshooting. I left my computer and monitors on while I was gone for a week (I use it for a security system lol) and when I came back one speaker has a randomly occurring crackle that sounds like a sampling rate conflict crackle.
I've tried the following:
Swap cables left/right
Swap speaker controller master/slave
Power cycle for ten min
And more and more... but even with nothing plugged in except power it will randomly crackle for about 5 seconds long then stop.
What is going on?
@Christian > Great to hear you resolved this - I was scratching my head a little reading your opening query. Glad its sorted!
