Mac OS X screensaver timer doesn't work, if soundflower audio is routed to any output #83

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. set system audio output to soundflower (2ch)
2. select routing of soundflower (2ch) to any other output in Soundflowerbed 
menu
3. set screensaver timer to 3 minutes
4. wait 3 minutes without touching the mouse or keyboard

What is the expected output? What do you see instead?
expected: after 3 minutes inactivity the screensaver should kick in
instead: no screensaver is activated after 3 minutes of inactivity

What version of the product are you using? On what operating system?
Soundflower 1.5.2, Mac OS 10.6.4, Mac mini 2.4GHz mid2010 HDMI connected to TV

Please provide any additional information below.
I use soundflower for routing all system audio to HDMI audio output, because 
the Apple HDMI audio driver doesn't allow volume control.
I could reproduce the problem multiple times. As soon as I've set the audio 
routing back to "None (OFF)" in the Soundflowerbed menu, the Mac OS X 
screensaver timer worked again without a problem. I've used the simplest apple 
screensaver which only shows the Apple logo and the computer name for testing.

Same here. We can see that the audio is preventing the system from sleeping:
