Toshiba laptop Satellite C55D-A speakers sometimes doesn't play

Hello everyone,

I have Toshiba laptop Satellite C55D-A and since some time I've had a problem with my speakers (maybe not a big one but annoying). The problem in question is that it sometimes doesn't play any sound at all from internal speakers until I plug in and plug out (at times several times) headphones jack and the internal speakers magically start working. Is there any way to get rid of this permanently or will I have to stick to this silly method?
