I have an 8500 432 MB RAM with a Sonnet 800 G4. No other add-ons except
a Radeon 7K. After several months of putting up with stuttering sound
and eventual loss of all audio until reboot, I've noticed that this only
happens when I place an app with audio playback such as iTunes, Audion,
QuickTime etc... on the Radeon 7K screen (either by dragging to it set
as the secondary screen or when already there as the main/menubar
screen) and try to play a file with audio such as a QuickTime movie, CD
audio, MP3 etc.... When I move it back to the monitor running from built
in mobo video support the audio plays fine. Sound works like it should
on both monitors in OS 9.1 and 9.2 but not 10. I've gone through an
upgrade path starting at 10.0 - 10.1 -10.1.5 - 10.2 - 10.2.3 - 10.2.4
-10.2.5 - 10.2.6, Clean Apple installs (no ATi drivers), except for the
help of XpostFacto 2.2.5 didn't even run the Sonnet L2/L3 cache enabler.
Same behavior each time. Then with the caches enabled. Also with and
without firmware ver. 2.0.8 for the Radeon card. Pulled the card to the
other slots, reset PRAM, used only one monitor, still the same effect.
What am I not doing? With all the radeon 7K users on the list has or can
anyone else duplicate this behavior on your setup? Is there a fix? I'm
sorry if I missed this in an earlier discussion if it already was.
Thanks,
Steve
