Sound: External Speakers Emit Sound; Built-in Speaker Doesn't

[J. De Salvo]

Hi, Fellow Dog Lovers--

I'm more curious about this than I am troubled by it, but  I'm hoping 
someone can enlighten me about this.

My G-4 Sawtooth with its built-in speaker rarely emits sound. On 
occasion, if I logout of KDE and restart X11 and KDE, sound will come 
through the built-in speaker. I get NO sound output from the built-in 
speaker out of Gnome--my preferred "window manager"--even if I logout 
and log back into X and Gnome.

However, if my USB Sound Sticks are plugged into my USB hub when I boot 
into Linux, I get sound with no problem, both in Gnome and KDE and 
without having to logout and restart X11.

There are times, however, when having the stereo speakers connected is a 
bit of overkill, especially for system notifications and the like. Why 
does the built-in hardware NOT work but the external USB speakers 
connected to a USB hub never fail?

Ideas on why this phenomenon occurs and what I might do to get sound to 
come through the built-in speaker?

Thanks.

Best,
--Joe
