I've been using my 920 as my daily music driver for around a year and a half now. I've paired it with my Senheiser CX300 II's since I've had it. A few weeks ago, I started having that scratchy sound every once in a while or the left earbud only giving out sound, which were fixed with a quick reset, but not Im having the issue of the music only playing clearly when the 3.5mm plug is set in a certain position, or when i press down softly on the top, pushing the jack farther into the port. This is very annoying as I have to put my phone in a weird position to be able to listen to music while walking or taking the bus, along with it being almost useless as my workout music device. Is there any known fixes or will I just have to replace my phone/get a new music player or disassemble it? I can't sent it to AT&T/Nokia as I loaded the WP8.1 Preview onto the phone and voided my warranty.
