Since I updated to 4.4.2 this Sunday past, if I try to listen to music or phone at more than three "clicks" up from zero, I get this awful static. I don't get this issue with my other devices using this same ear piece. (hearing aid interface) Mind you, for me, anything less than 50% volume is too low for me.
Before the update, I wouldn't get static until at least 80% volume and even then it was an occasional one. Now it's useless above 20-25%
When I get home I'll try using an external speaker. Thoughts anyone?
