I have finnaly started using my macbook pro internal speakers and I have encountered a serious problem. Sometimes the speakers sounds blown, they're muffled and static, sometimes the bass is gone and cuts off everything. After a while without paying attention to my mac, suddenly my speakers have been fixed! They are crystal clear again and have no problem with chirping or muffling whatsoever. I think this problem can relate to some audio mix programs that maybe exists thru third-layer storage and fucks me over somehow. I also suspect there could be a problem with connection between the subwoofer/speakers to the soundcard. The reason this is serious is because I work as a rental DJ to parties and need to show off my sample and work to the people renting me. Please help me, I don't have any cash or Apple Care left for this if there is a mayor problem with hardware.
