Today I've noticed that the left speaker of my headphones doesn't work when I plug them to my Mini Pro. I moved from CM10.2 to SJB 8.0 and found this out while testing stuff out. It's been some time since I've used my phone as a music player last time, but I never had any problems like this. Reverting to CM didn't help either.
I can't really find out whether this is a hardware or software issue. I think connector isn't dirty, wiggling the plug doesnt make any difference. Is there anything more I can try, besides flashing stock firmware? Did anybody have a similar problem?
EDIT: I've connected my PC to the phone as a BT headset, both channels work fine there.
