Keyboard Volume Controls Broken
i have a mac pro running 10.4.11. the problem i have is that even though i have selected +line out+ as my device for sound output, the apple keyboard volume buttons control the internal speaker volume. this happens every time i start my computer. the internal speaker makes the volume changing pop noises when i use these buttons, even though music comes through +line out+ just fine.
i have figured out a workaround. i can log out and then log back in. that second time i login, the buttons work correctly and i hear the pop noise in the line out.
i have tried running +repair permissions+ in +disk utility+ during the first login to solve the problem, but that did not work.
any help would be appreciated. thanks
mac pro, Mac OS X (10.4.11)
