Lost all sound Powerbook 17" OSTiger

[hgstudios@earth]

I lost all sound in my Powerbook, and my DVD drive is not ejecting a DVD. Not sure what caused any of this. Attempted the credit card trick (perhaps I got the angle wrong). Checked the sound settings, etc. as well as the midi setting. Could this be a sound board problem? Is there a way to check the sound board for damage? Could these two issues be related?

Regarding the disc, have you tried holding down the mouse button right after you hear the Macintosh startup chime after turning on the PowerBook? Hold it down and it should force eject the disc.

As for sound, have you played around with the sound buttons on the keyboard to see if maybe it was muted?

You could also try and zap the PRAM if none of the above work. Hold down Command-Option-P-R (Command is the name for the Apple key) right after the Macintosh startup chime. Hold it down for a few chimes and then let go.
