E430 Fix bad sound quality with Win 7 + Dolby Advanced Audio

Problem: In Windows 7 x64, sound quality is tinny and sounds very badly DSPed when Dolby Advanced Audio is activated. Even setting all effects off and EQ off the sound is bad simply because Dolby is/was turned on. Going to Sound > Playback > Speakers > Properties > Enhancements, checking Disable All Enhancements and clicking Apply clears up the sound, but then the EQ won't have any effect.
Solution: If you have Win 7 x64, uninstall the Win 7 driver (h0a114ww.exe) and instead install the Windows 8 driver (h0ac10ww.exe). Note that this is NOT the Win 8.1 driver - that won't install under Win 7. The sound quality will be way better when you use Dobly EQ and effects. So far I haven't had any stability problems.
I thought my E430 had the worst sound card ever until I upgraded to Windows 8 and installed the new driver. I have Windows 7 dual booted and found the sound quality in Win 7 terrible so I played around with it and found the above solution.
Solved!

Is it possible to get a refund if i bought an album with extremely bad sound quality?

As asked in the title, is it possible to get a refund if i bought an album with extremely bad sound quality?
I am very unsatisfied with my latest purchase of the album "Never take ffriendship personal" by "Anberlin" ...
I can find all the songs in much better quality, even on YouTube ...
I bought two other albums by Anberlin at the same time, on which the sound quality is much much better and perfectly clear.
is it possible to get some sort of refund ???

Very poor sound quality with 7g Nano through docking speaker. Sound through ear bud is fine. A different 7g Nano sounds fine through the same speakers. There does not seem to be debris in the lightning port. Any suggestions?

E430 Dolby Advanced Audio Issue

I updated my E430 with the Lenovo software update app and now get the following message when windows loads. Dolby Advanced Audio---------------------------The current Dolby audio driver version is 7.2.8000.13 and the software application expects driver version 7.2.7000.11. Please install a valid driver and software application combination. Anyone have the same issue?

Dear all,
I have also had the same issue but no luck fixing it with any of the suggested ways.
I have a new E430 as of one month ago which had this problem occur about 1 week ago. The driver was fine to start with, then not so much. I have a lot of distortion, low-level, constant buzzing in background, but when I put on an audio track of any sort the distortion is so bad I cannot run an audio file with any degree of content. I called Lenovo today and all I could get out of them was the suggested driver update to 8.54.42.0
I have tried all the fixes posted here:
1) First I tried the Lenovo fix: update to new driver from Lenovo site (8.54.42.0), which I loyally did, and it didn't fix the issue. It then after that appeared with the error message the same as Rob530's: "The current Dolby audio driver version is 7.2.8000.13 and the software application expects driver version 7.2.7000.11. Please install a valid driver and software application combination...", this was after the suggested lenovo fix of updating by installing the new version from the lenovo site over the top of the old driver.
2) Second time lucky? No. Uninstalled conexant, restarted, driver self-re-installed to put in the old version of conexant. Same issues just without the old start-up error message. 3) Uninstalled again, this time upon reboot windows installed microsoft default sound driver by itself without the conexant bit. Third time lucky? No, this strategy also didn't work. 4) Uninstalled entirely, restarted, while no driver installed the new version (8.54.42.0) suggested by Lenovo with no driver already installed. This time installed new driver with no error message but sound problems as back as ever with ultra-distortion of all sound. Please, please Lenovo get this sorted asap. I have stuff to get on with and can't be spending 7 days for it to go to a depot in the middle of paper writing for uni semester. I used to have an old X60 laptop which I loved (old but still running now) and was pretty confident getting another lenovo IBM ThinkPad (even talking it up to friends), but this after just a month of having it is not instilling confidence in new Lenovo products for me. A prompt fix and resolution of these issues would be greatly appreciated. I wonder if this is actually driver related. It could also be a deffective audiochip.Is the sound also distorted when you use headphones?

I need help with my Dolby Advanced Audio

After I upgraded my Windows 7 to Windows 8.
I am trying to open my Dolby Advanced Audio and something prompts me
"Cannot find .startup file!."
Can anyone help me with this issue?
Or can anyone provide a download link so I can reinstall or repair it?
This question was solved.

Hello, Foxseiz.
I see that you're having an issue with the Dolby Advanced Audio.
I wouldn't doubt the upgrade to windows 8 is causing this issue.
I would suggest going to your C Drive> SWsetup> Drivers/Audio> Right click setup.exe -- Application (not bit mat)> Select troubleshoot compatibility
Let it run through the process and then a box will pop up > Select troubleshoot program> then another box will pop up, you will need to select the option that says" The program worked in earlier versions of windows but won't install or run now"> Click next> Choose windows 7> Text the program.
Then the installer will pop up just click yes. After that is should begin the installation of the original program.
Let me know if any other issues come out during this process.
If you have any more questions let me know.

Solved!
Go to Solution.

Hi,
Try installing the Realtek Driver and reboot the system.
Open your C: drive and search for "dolby" in the search bar. It brings up an installer called “dolbyadvancedaudio.msi”. Run the installer and check if the dolby advanced audio application comes back.
Best regards,
Mithun.

6120c with 3.83 producing bad sound quality !

hi i got a new 6120c few days back and currently i have 3.83 V firmware , i am experiencing very bad mp3 quality when ever i use supplied head set which is HS47, that sound quality is below average or may be my phone is producing just mono not sure about it ... is nokia planning to come up with any new firmware for 6120c???
can we rollback its current firmware 3.83 to the orignal and older one which i think was 3.41 ????
thanks

Hi, did you use the Music Transfer application from Nokia PC Suite to transfer your mp3 files to the phone? If yes, probably your files were converted to .aac format to decrease file size and probably they lost some quality. This happened to me before. So I just used File Manager from Nokia PC Suite to copy my mp3 files from the PC to the phone's memory card as they are, without any conversion. This procedure solved the sound quality issues for me.

Poor Sound Quality with iTunes 8

I just installed iTunes 8, and all of the songs in my Library play with poor sound quality regardless of the view I have open. The sound is really muffled, but the voices and higher frequencies sound tinny and shaky. I tried playing with the Equalizer and Sound Enhancer settings, but was not able to fix the problem.
What can I do to get the iTunes 7 sound back?

I, too, am experiencing a significant decline in the sound quality of recordings in my collection. The recordings sound very muffled on the low, bass end of the sound spectrum, and the treble is significantly diminished. This decline in sound quality occurred immediately after I upgraded to iTunes 8. The sound quality in iTunes 7 was fine, and overall better.
It appears that my iTunes 8 attempts to improve the playback sound quality of songs with 128 kbps bit rates, as these songs in my collection do seem to actually sound better. However, most of my collection are recordings imported at the higher sound quality standard of 320 kbps from CDs that I purchased, and these recordings all sound poor since I've installed iTunes 8.

Why does my iPod have bad sound quality?

Hi!
I have an iPod Touch 8gb.
iOS 4.3.4
Jailbroken...
About 3 months ago, my headphone jack broke and was stuck in my iPod...
I got it out a week ago..
But the sound quality is really bad.
Theres too much echo, not enough bass and too much distortion and gain...

Based on other user's expereince, the headphone jack is damaged and requires replacement provided that the problem is only with headphones.

IPhones 3GS dead pixel and bad sound quality

As i was going through some photos i notice a small white dot then looking closer to the screen i recently notice about 4 dead pixels and also when playing music through headphones the sound quality is not clear. I tested my iphone and a ipod touch with the same song and the results were the ipod touch had better sound than my phone. Can apple fix this?? Thanks

As for dead pixels, Apple considers a small number as unavoidable with LCD displays and covers only a "high number" under the warranty. Apple would have to inspect the phone and determine if it's a covered defect. Make an appointment with an Apple Store Genius Bar.

10.6.2: Bad image quality with SIPS

I used to convert my PDF documents with SIPS like this:
/usr/bin/sips --setProperty format jpeg --setProperty formatOptions high -z 400 200 sourcefilename.pdf --out targetfilename.jpg
This results in a very bad image quality after updating to 10.6.2 (the text contained in the source pdf file is nearly unreadable in the resulting image, especially when using the -z attribute for downsizing).
I could reconstruct this behaviour with several machines today: when using 10.6.1 the quality is fine, but after the update to 10.6.2 the resulting image quality is unacceptable.
Any ideas? Or could this be a bug? The man page for sips does not contain any information about new parameters and the image quality for other target formats (tif, png, ...) seems to be ok.

That picture looks like it was taken in a dimly lit room.
You could try using night mode but you will need a very steady hand.
Most basic phone cameras just cannot produce good pictures indoors when not in brightly lit areas. LED flashes just cannot do a good enough job when compared to real cameras.
Megapixels don't equal quality, it's the lens and flash that make the biggest difference.

Has anyone else noticed the lack of sound quality with FaceTime in iOS 6, over wifi?

FT has lost much of its fidelity. It gates out all the noise, which I'm sure is supposed to be better, but now it's more like like a cell phone call. Sure the warmth of sound is better, but it cuts off breaths and sighs. All the things that make it so great when talking to your kids and family when traveling on the road.
If this was the cost of getting FT over 3G, it's not worth it.

Hi there, I have the same issue with FaceTime an ios6. When using it with iPhone 4 and 4s, the sound quality has decreased when compared to ios5. Background white noise is now reduced but low volume sounds (such as sights and whispers) are cut out too.
This is qualitatively not an improvement, and much of the warmth of former talks using FaceTime is now gone.
I do really hope there will be an answer from apple's side soon.
Cheers

Is there a solution for poor sound quality with ios7.03?

Hi all,
After waiting for a while and using 7.0.2 on my iPad I decided to upgrade my iPhone today. 7.0.3 was installed and while I am used to the general operation of the new iOS, I found that sound quality is terrible. The audio is extremely compressed. This was not an issue with 7.0.2. Unfortunately I also updated my 7.0.2 iPad to 7.0.3 and have confirmed that the latest iOS is at fault. Somebody really messed up.
Is it possible that I am missing a setting somewhere that was added with the latest update?

Never mind. After testing with my android tablet I found it was the headphones. They are Bose QC 15. The original battery was running down but work great yesterday. I suspected the battery and changed it but the problem persisted which led me to blame the upgrade. I should have known better. My apple devices have been flawless. Sorry for crying wolf...

Poor sound quality with NAD amplifier

I have tried connecting my airport express to a NAD amplifier and using my ipod touch as a remote. The sound quality is very poor - too much bass. I am using quality cables from the 3.5 jack to phono input on the amp. Any suggestions.

As Bob has eluded to, the key is NOT to use your system's PHONO jack for input from the AirPort Express. (ref: Using AirPort Express with the Phono jack on your stereo)

Windows Xp bad sound quality after installing itunes 10.5

After installing itunes 10.5 to be able to get the ios5 update my itunes plays every file with really bad, distorted quality. I try other players even Quicktime works fine. What could be happening?

Try to download, and install the latest Realtek HD Audio driver.
Here is the download link:

Select the second options (High Definition Audio Codecs (Software))
And when you install this, i think everything will be good.
