External soundcard damaged

[Psihobambi]

Hi, my Audiobox USB external soundcard suddenly stopped sending left output signals. To be exact it only sends them within a certain dB area. http://postimg.org/image/p6glhom8r/

When I try to twist the main knob a bit more, only right speaker works.(I've tried switching cables, so that sound from the left stereo field (left output) goes to the right speaker, and the exact same thing happens. Just to the right speaker.) http://postimg.org/image/yb0ibp6dd/

I've tried pushing that metal thingy inside a L output hole a bit with a screwdriver, and it solved my problem for an hour or so.

I am new here. Didn't find a thread that resembles my problem. Hope this is the right sub for this.

*I already tried putting some medicine alcohol on the knob.

I doubt the controls are the problem.
This sounds like a bad contact in the output connector. Get a new socket in exchange for the broken one.
