By chance I overloaded my tiny speaker beyond simple nonlinearity, and now it sounds like a sick piglet. I have a Dell Precision-M laptop, and Ubuntu 14.04 loaded in it.  No adjustment of sound panel helps. I cannot use it now for Skype, news, and background musics when I work.Most likely it is a plain mechanical damage (which would be a shame; I payed a top back to have a top Intel processor, and to have with it a low quality speaker doesn't sound right...), but I still have a little hope it is a fixable software problem. If this is true, is there any way I can fix it? If, on the other hand, it is a damaged speaker, can I replace it myself? (by first purchasing a new one)? or should I seek a professional help?
My laptop speaker produces pig-like sound; is it software or hardware problem? Any way I can fix it myself?
