TICKET ARCHIVE -> Help Stop Built-in Audio Out Switching

genepope - May 25, 2005 - 9:50 am

I am using digital audio out on my G5 (OS x, 10.4) and it keeps switching back to built-in audio when my machine sleeps or restarts. Is there anyway to prevent this so I don;t have to keep going into preferences each time and reselecting digital audio out?
thanks,
gene

Hi Gene,

Go to Applications -> Utilities -> Audio MIDI Utility and choose Digital Audio Out as the default output. This should solve the problem.

Let me know if this works.

Hi Gene,

Do you have a PowerMac G5 or iMac G5? That option should be there for a PowerMac G5 (look under Source). Do you have the Digital cable plugged in at the time (you should). If you couldn't see the device in Audio MIDI setup, how could you select it in System Preference?

Let me know if you have more questions.

Yes, I have a G5 and the digital cable is plugged in. It shows up in the audio control panel but not in the Midi setup. Interestingly enough, Garage Band does not show digital as an option either even though I can have the control panel open and have the digital output selected there.

Hi Gene,

That seems quite odd. Try resetting PRAM and see if things improve. If not give me the model number of your G5, and I'll see what I can find.

Zap PRAM and NVRAM:

No change. I can set digital out on the lower half of the midi panel but it doesn't show up on the upper half. Still get unseletinf of digital out on the prefs panel.
I have a dual 2.5 gHz G5 with 4 gig of RAM.

Hi Gene,

From the discussions at Apple, it looks like a Tiger bug. At this point I'd recommend you to send a feedback to Apple and hope they fix it in 10.4.2 or 10.4.3

Sorry I couldn't be of more help.
