Over the past few months I've been having sound issues, popping noises and momentary loss of audio as well as "robotic" type noise effects coming out of my speakers. I would usually just move the cable around which is connected to my 2.1 Creative external speakers via the 3.5mm output on the rear.
Lately the sounds and loss of sound has been happening more frequently and moving the 3.5mm cable doesn't seem to help. I very briefly connected my phone to the cable yesterday to see if I get the same thing but I did not. It was only for a minute or so as I received a call and had forgot about it afterwards.
I need a more definitive way to check this, if it's the wire or the 3.5mm output on my motherboard (Asus B150 MA) which is still under warranty. If it does prove to be from the pc itself, is the 3.5mm output on the rear the only possible cause or could it also be a software thing?
Here's a low quality sample of the "robotic" noises I recorded with my phone. You can hear it at the 8, 11 and 14 second marks.
