Windows 8 and Realtek HD audio ‘No sound after sleep’ problem – no reboot fix.

Many are currently having a problem with Realtek HD audio not working after resuming from sleep in Windows 8. The current fix of re-booting is a pain but I found a reliable way to get it working without a reboot

There is an argument between Microsux and Realtek at the moment over who is to blame so I don’t see a fix coming very soon.  From this link

“Bug report submitted to Realtek, and they have replied stating that the problem is with Windows 8, since the driver works fine on previous versions of Windows.”

1) Right click the speaker icon in systray (desktop mode) and select ‘Playback Devices’

2) Right click the ‘Sound’ window and make sure ‘Show Disabled Devices’ is ticked.

3) Right click the ‘Speakers’ entry in the list of devices, should have ‘Realtek High Definition  Audio’ and also show green tick as default playback device.

4) Select ‘Disable’

5) Right click it again and then enable.

6) If sound is still not working unplug your speakers from the audio out socket of your computer and then plug back in again.

7) You should have sound. Your done.

You will probably need to restart the media player or restart the browser, whatever your using, before audio will work for those programs.

[update] To solve this completely change your desktop power settings to prevent the system going to sleep at all. [/update]


Move Windows 7 from RAID 0 to Single Disk. How to

Having googled this a plenty and not having found an answer except for a lot of bad info like ‘it can’t be done’ (go figure?), I decided to create this step by step guide. Let me know if it works for other RAID modes, it should as the principle is basically the same.

While it will probably work for most of you, for those it does not and ignored the following warnings regarding backups, tough!

Make sure the data on your windows partition is small enough to fit on the single drive you will be restoring to. This guide assumes you are going to use one of the RAID set drives to restore to. If your going from RAID 0, then you will be restoring to a drive half the size of your RAID array. You only need the DATA size to fit. There is an option in Paragon  to re-size the partition to fit, as long as the data fits!

Check your BIOS Setup and make sure your SATA controller supports either SATA or IDE mode. If the only option you have is RAID or AHCI you will need to follow one of the many online guides to enabling AHCI in windows before you start. If you have AHCI then you probably want to use it, so even if you do have SATA mode you could enable AHCI in your windows first anyway (most likely you would want to use it), but is not required, as long as you have SATA mode AHCI can always be enabled later.

(Thanks NordicDreamer  for pointing this out,, note some BIOS only have RAID, AHCI and IDE, so you would use IDE mode instead of SATA at step 10. If you have both IDE and SATA modes then try SATA, if you BSOD at step 11 then try IDE mode)

Here goes — 

Step 1 ) Download and install the excellent (and free!) Paragon Backup.

Step 2 ) Do a FULL backup using Windows backup. You can store it on a 3rd hard disk, or USB drive or even another computer on your network. I used a networked computer. This is our emergency only, last resort, in case all else fails backup and will not be used if all goes well. Make the recovery disk when prompted. As a further precaution boot into the recovery disk and ensure you can access the backup. Do not skip this step! 

Step 3 ) Now do a FULL backup using Paragon Backup. Same location if you like (this is the one we will restore later). Make sure you backup the MBR, System Reserved (~100MB) and windows partitions. Minimum 3 ‘partitions’. If that’s all you have then fine, just make sure you backup ALL your partitions. The MBR is not, strictly speaking, a partition but you will see it listed.

Step 4 ) Create the Paragon backup/restore CD or USB (I used a USB thumb)

Step 5 ) Boot the Paragon backup/restore disk you created in step 4, and make sure you can access the backup you created in step 3, If you used the network like me, then you will need to set it up using the ‘Configure network’ option. If you cannot access the backup then you will need to move the backup. Just make sure you can access the backup using the Paragon backup/restore disk before you continue.

Step 6 ) Reboot and enter your RAID BIOS, destroy your array, do not create a new array.

Step 7 ) boot the Paragon backup/restore, now restore your backup of windows 7 to disk 0. Make sure to restore the MBR and the ~100MB ‘System Reserved’ partitions as well as the windows partition.

Step 8 ) Once completed you should now be able to boot into windows.

Step 9 ) Open ‘Device Manager’ and look for your RAID driver. Uninstall it. You should be prompted to reboot.

Step 10 ) Enter your Mainboard BIOS setup, Change the sata controller mode from RAID to SATA (you could try AHCI but if it wont boot you will need to follow one of the many guides on enabling AHCI).

[EDIT]  Many newer boards no longer have both IDE and SATA mode. They are both the same for the purposes of this guide so use whichever you have.  If you have both, try SATA and if you BSOD  try IDE  [/EDIT]  27/1/2014

Step 11 ) If all went well your done, windows will install the correct drivers for your sata controller and want to reboot again most likely, but basically that’s it.

How does it work?

The main trick is to get windows to boot on a single drive while it is still using the raid drivers. We trick windows by destroying the array, then restoring to a single drive, while the controller is still in RAID mode. If you try changing to SATA mode without first uninstalling the RAID drivers you will just BSOD during boot, even in safe mode. Once you have got it working you can then move the drive to another controller (after installing the controllers drivers of course) at leisure, should that be your goal.

If you just can’t get it to work, you have 2 fully working backups to play with, so just enable your RAID mode and create the array again, then restore using the Microsoft recovery disk  and backup you created earlier.

Email me using the Contact form and I will try to assist you. I am assuming, seeing as your using RAID, you know where to find things like device manager, windows backup etc.But if you are having problems then drop me a message and I will try to help as best I can, updating this post if required to help make things clearer for everyone.

Please do not bother me if you didn’t create both backups, didn’t make the recovery disks or didn’t check you could access both backups before destroying your array. If your data is not that important to you, just do a fresh install. It is probably what I will tell you anyway.



Sleep, not just a power saver

After 2 hours ‘dis-joint’ from an ensuing situation, to a completely different frame of reference, then returning ‘seamlessly’; the Nerdy Mind (currently on holidays in Silicon Valley) thought….

” it’s like your mind can hold multiple ‘objects’ of situation, pathological and emotional state (to name but a few of the various existing objects that must be consulted for properties); so allowing to being able to restore almost perfectly the same mood, perception, state of mind, physiological and psychological modifications as required, when you return to that situation.

As long as they are quite ‘dis-connected’ with little object interaction then those daily objects would be very specific to the task in hand.

Would that explain why sleep is so important? So you can take time to process the daily collection of objects and cross reference the data to provide improvements or additions to your daily working object set? ”
