Power Macintosh: No Sound With Audio CDs (5/95)


When I play an audio CD in the built-in CD ROM on my Power Macintosh I am unable to hear any sound. The CD mounts on the desktop, AppleCD Audio Player opens and the time counter moves when I press play, but there is no sound. What is causing this problem?

You need to enable the audio playthrough option in the Sound control panel.

Step 1
------
open the Sound control panel

Step 2
------
From the pull-down menu, select Sound In.

Step 3
------
Click the option button

Step 4
------
Click Internal CD, and Playthrough.

After selecting the internal CD and Playthrough options, you should be able to hear audio CDs on your Power Macintosh computer.


Additional Troubleshooting
--------------------------
If you still do not hear any sound after setting the CD options properly, open your Preferences folder (in your System folder) and throw away the AppleCD Audio Player prefs and Sound Prefs. After throwing these files away, follow the previous steps to reset your Sound control panel.
