i've been reading a lot about new iMacs having issues with sound and flash. since installing SL, my 2006 macbook has had issue similar to those being reported. flash starts to eat up my CPU and then starts to lag and sound gets really choppy. all sounds on my computer are affected. i can solve this by plugging in my headphones into the jack or closing the macbook lid and reopening it. does this sound like the same issue or has it been found to be iMac specific?
