Sound distorion e6320
I have an ongoing sound quality issue, which exacts as follows:
1. Sound via headphones is fine.
2. Sound from speakers is distorted (disturbing during skype calls, etc.), but upon closer observation, it appears that the distortion is only coming from the left front speaker and the sound that is coming from the right front speaker seems fine. It must be that the left side distortion sort of "washes' out the good sound from the right side.
Before I go any further, would folks agree that this sounds like the left front speaker is somewhat "blown" and I need to change the speaker assembly (which seems to come with both the left and right together) or is there any chance it might be some other driver related problem?

It does appear to be a bad speaker but to rule out the driver do this.
Open the Device Manager and expand "Sound, video and game controllers". Right click on "IDT High Definition Audio Codec" and select to uninstall. Put a check mark in the option to delete the files, and then ok. When you reboot, Windows will either install its own native driver or another IDT driver if there were any other versions on the hard drive. So go back to the Device Manager and check for an IDT driver. Keep uninstalling & rebooting until IDT no longer appears under Sound Controllers and "High Definition Audio Device" appears in its place. That will be the native driver.
Test the speakers while using the native driver, then download and re-install your IDT driver. If you get the same symptoms with both drivers you can rule out the drivers as the source of the problem.
There is a balance control of sorts on the Levels tab of the Speakers properties. It might help in your listening tests.

Thank you for your quick reply. I don't have the icon "IDT High Definition Audio Codec", but simply "High Definition Audio Device" as shown below. Does this mean I only have the Native driver installed? When I uninstall this driver and restart the computer, it reloads the same driver and I do not find any option to delete the files prior to restart. Do you have any other advice?

Yes. Go to the Latitude E630 downloads page. Select your operating system. Expand the Audio category and obtain your IDT driver and install. Test the speaker.
When going from the native driver to the manufacturer's, no need to uninstall the native driver.

After downloading and installing the IDT driver, the sound is the same. I am guess that the most likely culprit is now the speaker. Would you be in agreement?

Yes. For absolute certainty perform Factory Image Restore.
To obtain your service manual go to the E6320 documentation page and download the one named "Owner's Manual".

I spend yesterday backing up all my files and making notes about what programs I will have to re-install, but oddly, when I went to do the restore, it says there is no restore image on my hard drive. I knew I had made some sort of backup files one on my external hard drive when I first bought the PC in the summer of 2012, but as directed, I made a restore CD to boot from which auto-selected one of the files from my external hard drive, but after the restore process was finished (which seemed to only check and make repairs automatically, and no visible changes to the PC, I am now wondering if when it made the bootable CD if it selected the wrong image. I seem to have two different files on my external from around that time. One just says "PC" and is 267Mb, and the other says "Windows Image BU" and is 22.4Gb. The file size on the bootable CD I made is a little under 400Mb, so have I possibly selected the wrong file to make my rebootable CD, which I was directed to label "Repair Disk Windows 7"? Also, if I do need to make a new bootable CD to perform the restore process correctly, how would that be possible due to the size of the image, relative to the size of the media (770Mb for a CD and 4Gb for a DVD)?

This is outside my area but 22.4Gb seems like it could be it. I have a Windows 7 Pro re-installation dvd which is only 5.23Gb.
The size of my Win 7 repair disc is 326Mb. The instructions said it could boot up the computer, or it can restore Windows from an image. It does not itself contain Windows.
Like you, I have my backup on an external hard drive. I did not use discs because I have the Windows re-installation disc. The Windows OS part of my backup is 34.44GB. Or that what it says in the Windows Backup and Restore tool. I have Virtual XP running on my laptop along with Win 7, so I think that means my OS backup is bigger than normal.
As far as doing it for diagnostic purposes, a new one would not be of any use, since you will only end up with the same configuration you have now.
If you have technical questions about all of this, probably someone who's area is windows can answer better.
