5.1 speaker problem after hard drive crash They worked fine before

[Shinyo]

So a hard drive crashed, not catastrophic since I back all the important stuff but a pain in the butt since it was the one windows lived on.
Reinstalled win, downloaded all the latest drivers from MSI.
But now the RR and sub-woofer do not work. I have been trying various things for hours and now need to ask for help. Any you could give would be appreciated.

They are 5.1 Dell speakers with the three jacks coming from the MOBO to the sub then to the other four from there and worked fine before the crash. BTW the fronts work fine as does the center which shares a jack with the sub.

What I have done:
A: Checked all cables but since they were never even unplugged that is not an issue.
B: Re-reinstalled the audio drivers. (realtek 6.0.1.8010)
C: Switched the rear speakers to the side speaker jack and told the audio mgr I had 7.1, that worked for the RR but not the sub.
D: I read in a post that there could be interference from the graphics card audio and it should be disabled in device mgr. I did not see anywhere I could do that there but did see a setting in Nvidia control panel where I could turn off audio for the HDMI port which I did.
E: Flipped every virtual switch I could that looked like it might have an effect.

Sorry for being so verbose but I figure the more details the better.

Thank you for the input, I had not tried getting the drivers straight from Realtek. However after installing them there is no change.

Thank you for responding,
Yes, that is case.
Speakers
Realtek High Definition Audio
Default Device
Is the only option not greyed out. There are four identical others listed as NVIDA Output not plugged in.
All enhancements are disabled but when I swapped center for sub I did get bass from the sub and nothing from the center and of course that did not effect the right rear.

Update:
I may be narrowing it down or taking a wrong turn.
In the device mgr down under sound, vid... controllers is listed Realtek High Def Audio. Well and fine but at the top under Audio inputs and outputs is listed "Speakers (Realtek High Def Audio)" In the events for this is an error "Device not migrated"

Details are:
Device SWD\MMDEVAPI\{0.0.0.00000000}.{b2119ee6-8dba-4e0b-b355-78df7df9d9e6} could not be migrated.

On the driver tab for this device the driver details button yields the message:
"No driver files are required or have been loaded for this device."
but on the details tab there is all sorts of information about the driver such as the version 10.0.15063.502

I am on a learning curve with this stuff and have no idea what all those codes mean.
An old post on a similar issue suggested doing a SFC scan which I did - - neg result. I also reloaded the chipset drivers, grasping at straws here.
About the only thing I haven't done is flash the bios.

Update 2.0
I would still like to get them fixed but I figured out a work around. I plugged the rear speakers into the side speaker jack and told the computer I have 7.1.
Then in the enhancements tab I swapped the center and sub.
So now the center does not work but that is better than the way it was. My two front speakers are yard high Marantz's so they can handle the bass when playing two channel music and the sub should work when gaming.
