Random problems with Sound

After updating from 10.5.2 to 10.5.3, has anybody had random problems with the sound/speaker icon displaying on the menu bar and sound coming out from the onboard speaker on the PowerBook G4.

Some odd things I noted:

When restarting, there is sound coming from the laptop.

In the 'System Preferences...' > 'Sound' the onboard sound is disabled. No input is detected, no external output is detected. The option to display the Sound volume on the menu bar is enabled, but not displaying. The option for sound is muted, but it is inaccessible where it cannot be unchecked. 😟 * sounds like a PC ...grrrrr

Takes about 2 to 3 reboots to get the sound back and restored.

PowerMac G5,PowerbookG4, Mac OS X (10.5.3)

I'm having the same thing here but it goes back before yours. It has been happening for about 8 months now. A simple restart does the trick. I'm thinking it is a software at start up issue. It doesn't seem to recognize the sound card. Wish they would address it.

I'm having the same problem...could it be an issue with the recent Leopard update?? I've only noticed it since the last update. I've tried restarting my computer twice tonight with no effect. Has someone reported this to Apple yet?

Restart used to do the trick for me, but no longer. Mine has also stopped making a startup chime unless I hold down command-option-P-R. I called AppleCare, and they want me to show my PB to a Genius. The problem seems to involve PowerBook G4s.

Software or hardware issue?

Try to plug in and out a headphone... does it for me and is quicker than a restart.

Plugging in a headphone makes no difference for me. Do you have a PowerBook G4? When I booted from a partition on an external hard drive containing 10.4.11, my sound came back! But then when I rebooted from my internal hard drive, the system menu volume indicator was greyed out again 😟

So it seems that there are two possibilities:

1) This is a bug in Leopard
2) My install of Leopard has somehow been corrupted.

Yes... I have a G4 17'' 1GHz.

The problem appears since the update to 10.5.4. If the sound disappears, I plug a headphone to the jack, hit one of the volume buttons, and then I have sound again.

I called up AppleCare, tried rebooting with the shift key held down, to no avail. However, the tech support guy had me look through /Library/Audio, and it turns out that there was something weird in /Library/Audio/Plug-Ins/Components:

A52Codec.component

This was installed by Pierian 1.1. I removed it and rebooted, and all was fine. So there's definitely an incompatibility between Pierian 1.1 and OS X 10.5.4.
