Monitor suddenly going to sleep while playing a CD.

With the screen set to go off after 20 minutes of inactivity... it will.
In other words, if "nothing" on the screen changes (images, mouse cursor movement, etc.), the screen will go off.

When you say: "play a CD", I assume you mean a music CD.

I have my screen set to go off after 5 minutes. When playing music, I use WMP, and have it set to show a waveform, that changes with the music. This keeps my screen ON.







Keep in mind, that anything that moves the mouse (cursor) even the tiniest bit, will keep the screen ON.
For example, loud enough music can move the mouse, especially very sensitive mice.

I frequently play CDs. I have the settings so that the screen goes off after 20 minutes of inactivity.
However, when I play a CD (and they're all longer than 20 minutes), it usually waits until it's done playing, then the screen turns off right after.
Today, the screen has been turning off while it's playing. And not waiting until the end, or sometime thereafter.

WMP has a setting that stops the screen going off. Perhaps you have set that setting.

Check in WMP, Organise, Options, Player tab - Allow screen saver during playback.

I also have that Option... UNchecked.

Yes, I knew that from your first post.

The OP also needs to unset that setting.

Yep. I just tested again. It's NOT the waveform I show in WMP, it's that checkbox.
Good look Denis.

I know nothing about VLC but you might try looking through VideoLAN's wiki website.

Best of luck,
