I need help!!! DVD Playback problem on G5!!

[msharp]

anyone could help me with the dvd playback problem on G5(i don't know if this problem only shows up on G5s)??

i inserted a dvd disc, and the dvd player shows up with no sound at all!!
and after that i checked the Sound preference in the System Preferences panel, the output setting was changed to Built-in Audioigital Out instead of the correct setting: Built-in Audio:Line Out.

And, the setting was grey that i can't even change it back to normal... And the whole system was muted...

The only way to resolve this problem is restarting the machine.

i've tried several times but the problem stills, and i've searched all over the web(via google) with no result.

Thanks everyone in advance....!!

Does it happen with every DVD, or just one? If it only affects one, try going to that DVD's audio setup menu, and make sure it's not set to DTS (which Apple's player won't decode).

You could also try using VLC for playback.

NB: I don't own a G5.

I'll guarantee you that it is a G5 only problem. It is the only Apple computer with the Tos-Link Fiber Optic Digital Audio in/out ports. How old is the computer? Call Apple, your sound card may be bad.

I remember one time playing a dvd with no audio being apparent, it turned out that the volume on DVD Player.app controller was all the way down to nothing.

Try playing the DVD in VLC or a vob in QT to see if you get sound there, then try deleting DVD Players prefs.

my G5 is only less than a month old...so i think it can't be bad... although this is the first time i bought products from apple, I think i can trust in apple, also trust in their products.
