Lost my volume controls? Mac G-4 tower, OSX 10.4.11
Hello,

This just started today. Mac G-4 Quick Silver running OSX Tiger. My volume controls keep ramping down. Can't hear sound.
States that selected device(internal speakers) has no output control. Can anyone tell me how I can fix this?

When I go in the system prefs, under sound it reads as: internal speakers, when I put in headphones it shows the difference. The port reads as: built-in audio. Below in the gray area it shows: Settings for the selected device: The selected device has no output controls. Then below that it reads:
Output volume and the mute button is selected. When I go to unselect it pops back on. The speaker itself works, because during various reset attempts I could hear the chime. I can also hear headphones and speaker for brief moment when I manually try to adjust volume control both on key board or in menu, but it will not hold, it drops back to zero.

Weird part is that about 2 hours ago everything seemed normal again and itunes played and I was able to adjust volume without any problems. Then about hour later the volume gray box popped back up on my desk top and went to zero again(all the way to left) with no sound and now the box will not go away. Light gray with volume symbol.

Any thoughts? I'm baffled. Recently put in wireless card and airport extreme base, but when I disconnected problem still occurs.

Thanks again,

Bingball

Hi, I have the exact same problem now in July 2009, it all started 1 month ago.
No special stuff on board, just a standard PPC with Leopard 10.5.7 !!!

I got it fixed by applying a paperclip into the speaker phone input !!!

I was having the same problem. I tried various things. Reset Pram. Threw out system prefs. etc.. I then read this thread and saw the paper clip solution. I then just simply put my headphone jack in to the headphone imput slot and viola... my sound came back. I'd like to know what happened and why this fixed the problem. Thanks for your tip.
