| Subject: [Audacity-help] Audacity question
| I tried Audacity to see if it would work for me, it does. But I've
| lost the audio on at least 2 other pgms (OK they are games). I tried
| some other pgms that seem to be OK.
| I have a dual 2GHz powerpc G5 running os x 10.4.7
| I checked the sound preferences panel, everything is as it should be.
| I reinstalled one of the pgms, still no sound.
If you click on the MAC hard disk and then click on Applications >
Utilities > Audio-Midi setup, you will see the reason for the problem is
that Audacity has changed the sound settings including most likely
raising the sample rate to 48 000 Hz or more. Audacity does this to give
the best recording quality your system is capable of, however unlike
other operating systems, sound settings in OS X apply to all applications
unless they forcibly change them. Unfortunately many other OS X
programs do not check what settings are currently applied when they
are started, and assume default (sub-optimal) settings are in force. If
the settings aren't what they expect, they are incapable of changing the
system settings to their requirements, or even throwing an error
indicating this is the problem. Instead they stop working or produce
To get round this, make sure that your sound device is set up (in the Apple
Audio-Midi Setup) to work in stereo, 16bits, with a sample rate of 44100Hz
or 48000Hz and have the same settings in Audacity, as set on the Quality tab
of Preferences. This should allow pretty much all software to work (although
you will lose the benefit of high-performance sound hardware) and prevent
further settings changes.
Alternatively restart, then try installing this preview release of Audacity
1.2.5 which should fix these problems
If you still find that other applications lose sound after running Audacity,
turn on the new option
"Do not modify audio device settings (such as sample rate)"
at Edit > Preferences > Audio I/O tab. Then in Preferences > Quality
tab, set Default Sample Rate to 44 100 Hz or 48 000 Hz and the Default
Sample Format to 16 bit. Set the Project Rate button bottom left of
Audacity to the same value as the Default Sample Rate setting. Close
Audacity then change sound settings in Apple Audio-Midi Setup to the
same settings as Audacity (i.e. 44 100 or 48 000 Hz, 16 bit). This
should prevent any further conflicts.
