I've got a rare weekend with nothing to do, so I'm getting some housework done. I have iTunes playing for some background noise. Every 20 minutes or so, it just stops playing; if I move the mouse it starts again.

I'm on Windows 7 64-bit. My power settings have my monitor turning off at 10 minutes and hard drives at 20. Both sleep and hibernate are disabled.

"Aha!", you say, "Clearly when the hard drive is turned off iTunes is stopping!" Not so. I fiddled with the settings and changed them to make the hard drive sleep in 5 minutes, and iTunes kept playing for the 7 minutes I watched it. I'm currently trying to see what happens if I set the hard drive to never turn off, but I'd prefer to leave it at 20 minutes to save minor amounts of energy. (Edit: I just set it to 240 minutes, and it stopped at 20 minutes. It seems tied to when the monitor turns off; that seems odd and I'm testing that now.)

What other settings could be the culprit?

How have you connected your speakers? Is your computer connected to an amp? How is it connected, analogue, optical, HDMI? – Sandeep Bansal Apr 21 '11 at 22:11
Did you solve this? – Mr.Wizard May 10 '11 at 17:41
The hard drive should turn off 20 minutes after any activity, I believe - iTunes trying to read song data would count as activity. – Phoshi May 11 '11 at 19:57

I had this happened to me because my audio output was via my HDMI cable, so when the display turned off, so did my audio. One way to fix this is to change your power settings to never turn your display off. Something I'm testing is to see if enabling the iTunes visualizer will prevent the display from going off.

I forgot about this problem; people are still asking about it.

Some time after asking the question the behavior went away. Perhaps it was an iTunes bug, perhaps it was a driver failure. I don't know. I never figured out the cause, so I can't really say what happened. Since it doesn't look like there's any "me too" answers I assume it was something unique. I'd say close the topic but it looks like that's reserved for worse things. Oh well.

Possibly the monitor was connected to the speakers directly. Therefore letting the monitor sleep would also let the speakers sleep.
