There appears to be a sound bug in OS X 10.3.6 affecting some MDD G4 towers as mentions by me and a few others at the macrumors.com forum (I posted in page 6).

After installing the 10.3.6 update, the sound is apparently louder (including iTunes) despite no apparent visual changes to the volume control. Mine was set to 10/16 in sound increments but the sound was loud that the same 10/16 sound increments setting in OS X 10.3.5. When I put the system to sleep and wake it up the sound volume appears to be at 92% ~14/16 setting in sound increments and I have to manually lower it back to 10/16 sound increments. After I corrected the sound it stayed fixed until the next restart.

Can someone notify the Apple Engineers about this so this bug gets resolved? I don't want to downgrade back to OS X 10.3.5 over this.

I have the same problem... I had to go into Audio Midi setup and manually set sound output to 0.0 decibels. Before that it was at +12.0 decibels and horribly distorted sounding!

Apparently there is a sound volume & quality prob with MDD and OSX 10.3.6 update, Many are talking about it in the Apple Forums (under OSX Panther) and Macrumors.com.

I didn't experience any distortion or sound quality problem just the volume being louder.

I tried to zapping the pram but the sound volume remains.

The temporary solution:
I either have to unplug or replug my speakers or to put the MDD to sleep and wake it to get the sound to show it's true sound values then I manually reduce it back to my original sound volume increment with the sound keys on my keyboard.

But the sound volume problem will resurface when I restart.

I am also having this problem. It's quite annoying! For now I'll either have to learn to keep my computer on all the time or unplug and re-plug the speakers every time i start up. Bleh!

I'm having the same issue. Sound resets to maximum at every reboot. Very annoying to say the least. Hope someone can find a fix for this.

Update: I have MDD 1.25 GHz G4

I see you have the same MDD867 that I have, but yet I am not afflicted with this problem.
