Home Forums Mac Software Mac Operating Systems Can't change startup volume

Installed 10.6.3
Installed 10.6.8
Had font problems, did a lot of troubleshooting, including zapping the PRAM.
Gave up, reinstalled 10.6.3


Headphones are plugged in to the imac, but the start-up sound is coming from the imac speakers. Loud. Adjusting the volume vertical slider in the menu at the right upper corner of the screen doesn't affect the volume.
