Headphone Jack cuts out off and on
Out of the blue, I noticed that when listening to music, the audio track cuts out in the right side or makes a scratchy "half there, half not" sound. I thought it was just my headphones, but plugging them into speakers at home produced the same result. I'm worried it might be the headphone jack. I tried blowing into it and a Q-tip was too large for the hole. If it is the jack, is it covered under the 1 year warranty? And: is there any fix for this at home?
