Sound off after Sleep

Windows 7 / E205 S1904 / Realtek HD Audio Manager/   After sleep about 33% of the time there is no sound. If the laptop is shut down, the sound usually comes back. Have reinstalled the driver from Toshiba site. Any suggestions?
Many thanks

Answer 1

This appears to be completely a Realtek Software (Driver) problem, that Toshiba is not getting Realtek to fix even a year after the issue has been brought to public notice.
No permanent fix can really be made unless Toshiba compel Realtek to fix their driver software.
As for the work-around shown in an above post, after even further tweaking, it was noticed that the Microphone resetting usually does not need to be done.
So,to restate:
When putting the laptop to sleep and waking back up in a different power state than it went to sleep in, sounds stop working.
Example: Power plugged in, put laptop to sleep, power unplugged, wake up laptop, no sounds (and no microphone).
A reboot fixes this. This means it is a software (driver) problem & not a hardware problem.
As can be seen from the suggestion above, putting the laptop to sleep and starting up again in the same power mode that was in effect before the sound was lost, was one solution. However this is random, sometimes it works, more often it doesn't, and it is often inconvenient to put the laptop to sleep again when it is noticed sound is not working.
The quick fix, more concise  (workaround) that seems to work most all the time is:
Unplug the power
Click the Start button, type in the "Search Program and files" box: Sounds
Select: Change system sounds
Select the: Playback :tab and right click on: Speakers (Realtek)
If : Show Disabled Devices : is unticked, Click on: Show Disabled Devices : to ensure it is selected (ticked)
Right Click again on: Speakers (Realtek)
If : Show Disconnected Devices : is unticked, Click on: Show Disconnected Devices : to ensure it is selected (ticked)
Right Click again on: Speakers (Realtek)
Click on: Disable
Right Click again on: Speakers (Realtek)
Click on: Enable
Plug the power cable back in
In case this does not work, use the procedure shown in the post further above where the microphone is also disabled and enabled.
If by chance you do this and you end up not being able to find your Speaker or Microphone icon in the Change sound card settings (Change System Sounds) dialog:
Click the Start button, type in the "Search Program and files" box: fix sound
Click on: Find and fix audio playback problems & go through the fix steps.
Repeat above step for Find and fix audio recording problems
This usually gets back an audio device that has been disabled and cannot be found in the "Change sound card settings" dialog. (It does not ever fix the "no sound" problem.)
Again, this is a TEMPORARILY FIX to this VERY IRRITATING LONG PENDING PROBLEM that has been neglected by Toshiba and Realtek.
Laptop: QOSMIO F60
O/S : Windows 7-64bit
All drivers and Windows O/S software up to date.
One ends up having no choice but to believe that the management of Toshiba does not really care all that much about its customers when they leave a known problem unfixed for years. That is sad, considering Toshiba's slogan is "Leading Innovation." A broken innovation is just that, broken, and a real leader does not leave its products broken.
