when playing a cd and the computer screen is set to 'turn off' after a set time due to inactivity. When the screen 'turns off' the sound stops also.

[Norman Mitchell]

the problem is with sound (playing a cd) when the power management time out kicks in and the screen powers down. The sound stops also. If I press a key to restore power to the screen the sound returns. The playback keeps going whilst the screen blanks.

Hi Norman,

The warning reported here typically indicates that it took longer for your system to resume from suspend than expected. I believe there is a 5 sec barrier which your system likely exceeded. Based on your dmesg output I see PM: resume devices took 6.684 seconds. A patch to prevent this warning has been applied via bug 464552. As a result I'm marking this as a duplicate to bug 464552. Please continue to track this issue at that report. Thanks!
