Is it possible to get sound from both the headphone jack and the internal speaker at the same time? I have a stereo hooked up to my iMac and everything sounds great. What I'm wondering is this. Is there a way to have sound come out of BOTH the internal speakers and the headphone/audio out jack? I haven't found a simple soultion obviosuly, but is there any kind of work around? I know can buy a pair of external speakers and all would be fine. But I'd like to not take away from the output of the headphone jack. So then I was wondering if I cannot have the internal speakers work in conjunction with the headphone jack, if I get a pair of firewire or USB speakers so as to not take away from the headphone jack, will they even work since I have something plugged into the headphone jack? I'm guessing they would still work since they are independent from the jack, but I'm not sure. Any help would be greatly appreciated!
