Muted sound after S3 standby
Symptoms
Windows Vista or Windows 7. System sound has been muted after resume from S3 standby.
Cause
When a recording is ongoing when the computer is asked to sleep, it enters away mode, which turns off the display and mutes the sound.

Soloution
Create a Scheduled task that executes a command after resume.
An exellent description of this is found here: http://www.pcmediacenter.com.au/forum/topic/30303-auto-run-program-after-resume-from-s3/
Use a system information event resuming from sleep as the trigger. Here's how:
- Open task scheduler (press windows key, type task, click on task scheduler at the top of the menu list)
- In Actions (menu or right pane) click 'new task'
- In General tab, give your task a name
- In Trigger tab, click 'new'
- Choose 'on an event' in the top drop-down list.
- Choose 'custom' radio button
- Click on the 'new event filter' button that now appears.
- For event level, choose 'information'
- In 'event logs' drop-down menu, choose windows logs > system. Put a tick next to 'system' only
- Click on the text 'All event ID's' (the text will clear) and insert 1
- Click ok
- In the 'Actions' tab, choose the program you want to start by clicking 'new'
- In the 'new action' window, use the browse button to navigate to the .exe of the program you want to run. If you have a shortcut on your desktop for the program, you can simply choose that and scheduler will extract the path from the shortcut.
- (optional) Add -fullscreen to the 'arguments' box if you want your program to start full screen and it supports this switch (argument)
To 'unmute' the system sound use a freeware command line program NiCmd found here: http://www.nirsoft.net/utils/nircmd.html With the following command: "NiCmd.exe mutesysvolume 0"
