Just got a new computer and brought eveything over from my old computer. When I play iTunes the first song plays with sound - out to my computer internal speakers and to multiple speakers via airport expresses. Everything worked fine on my old computer and as I say - the first song I play works but then the next songs "play", but without sound to any speaker. Everything is up to date Tiger 10.4.10 iTunes 7.4.2 (eveything was up to date on my old computer as well.
Should add that I ran "Cocktail" after all updates.
