Dolby Audio Driver stopped working

I've been using my IdeaPad for a few months, and all of the sudden it no longer plays the audio in any of my downloaded files. It'll play audio in other contexts, like if I watch a video on YouTube--but not on anythign that I've downloaded. And when I restart my comptuer, it tells me that the Dolby audio driver isn't working. It doesn't tell me which driver it's talking about. I believe the driver was the Home Theater v4, but I could be wrong. I uninstalled it and reinstalled it, restarted my computer, and it's still giving me the same error message every time: Dolby audio driver isn't starting. What should I do?

Uninstall the Conexant audio driver (don't select the option to remove the files though) and restart - this will cause Windows to reinstall the driver during the restart. Alternatively download the Conexant audio driver from the Lenovo drivers page and install it. Either of these two methods work fine.
This should fix the Dolby problem.

You can try one of the following (start at 1 first):
1. Run in an elevated commnad prompt without the quotation "sfc /scannow & dism /online /cleanup-image /restorehealth"
2. Restore to a date where you can remember that the dolby audio sound is working.
3. Use OKR to restore everything to factory default. Note you need to backup all your personal files before doing this and might need to reinstall all third party programs after the restoration.

Hi mido112k,
I understand that you are having a problem installing the Dolby Home theater on your HP Pavilion G6-2321ee Notebook PC. I will try my best to help you with this.
I suggest that you restore the original Performing an HP System Recovery (Windows 7) and then install the update driver.
I hope this helps, please let me know.

USB audio DAC stops working after suspend

I didn't update my mediacenter running arch for a few months so I figured i'd reinstall it because of the filesystem, /lib and grub changes. Now after reinstalling I'm running into the issue that my USB audio DAC stops working after a suspend.
After a suspend speaker-test gives me the following error:
[user@mediacenter ~]$ speaker-test -c 2
speaker-test 1.0.25
Playback device is default
Stream parameters are 48000Hz, S16_LE, 2 channels
Using 16 octaves of pink noise
ALSA lib pcm_dmix.c:1068:(snd_pcm_dmix_open) unable to open slave
Playback open error: -77,File descriptor in bad state
I've tried replugging my DAC and restarting ALSA, without any success. I have to reboot to get sound again.

Unless you can find a way to stop XBMC from using your DAC, I would try hunting down the update which broke it and file a bug report with the appropriate project. https://wiki.archlinux.org/index.php/Do … g_Packages.

Yes I am suspecting the kernel as well. I'll try to change some options in XBMC to maybe get this working, and if not I'll see how far I can downgrade with the kernel. My last installation was a few months old so I hope it broke not that long ago.

Unable to start the Dolby audio driver after updating windows 10

I am using a Lenovo Laptop G510 that came with Windows 8 preinstalled. Yesterday I updated it to Windows 10 and after that whenever I boot my pc to desktop I get an error message saying that "Unable to start the Dolby audio driver". I have already tried uninstalling and reinstalling Audio driver from my computer but still the error comes up. Does anyone know how to solve this problem? Thanks

hi Abrahamjoy,
Can you try these steps:
1. Follow this guide on how to disable automatic driver installation.
2. Press the Windows key‌ +X and choose Device Manager. On the Device Manager, navigate to
- Sound, video and game controllers > right click on Conexant SmartAudio or IDT High Definition Audio > choose uninstall > and ensure the delete the driver software for this device is checked.
3. Press the Windows key‌ +X and choose Programs and Features. On the list of apps, uninstall anything that relates to the Conexant/IDT & Dolby then reboot.
4. After the reboot, download and install the driver below (this should install the audio & dolby components)
- Audio Driver (Conexant) for Windows 10 (64-bit) - Lenovo G410, G510
When finished, you the audio & dolby settings should now work and the errors should not pop-up anymore.
Edit:

Let me know how it goes.

It sounds like you may have multiple problems, but none of them are likely to be caused by malware.
First, the internet-related issues may be related to adware or a network compromise. I tend to lean more towards the latter, based on your description of the problem. See:
http://www.adwaremedic.com/kb/baddns.php
http://www.adwaremedic.com/kb/hackedrouter.php
If investigation shows that this is not a network-specific issue, then it's probably adware. See my Adware Removal Guide for help finding and removing it. Note that you mention AdBlock as if it should have prevented this, but it's important to understand that ad blockers do not protect you against adware in any way. Neither would any kind of anti-virus software, which often doesn't detect adware.
As for the other issues, it sounds like you've got some serious corruption. I would be inclined to say it sounds like a failing drive, except it sounds like you just got it replaced. How did you get all your files back after the new drive was installed?

CD drive stopped working on my Satellite L

Hi
MY CD drive stopped working, but then it recognised a disc which I had inserted, but then stopped working again.
I have deleted upper and low filters from device manager.
I have also downloaded the dvd ram driver from toshiba and my cd drive then worked, but after I closed down the computer, again it would not recognise discs in the drive.
I again downloaded the driver and it then recognised the disc I inserted into the drive.
However, now my computer will not recognise the drive even when I again download the driver.
Does anyone know why it would work intermittently or have any ideas that might help.
Thanks.

Which satellite L do you have?
Which operating system do you use?
Do you use original Toshiba recovery image?
Is ODD recognized properly in device manager?
Which disc do you use?
Do you have this problem using only this one disc?
Sorry buddy but your description is so general and there is no one single relevant info that can help for better understanding.
What you can expect are just general answers like:
-reinstall ODD
-test with different discs
-defect ODD

Intel wired ethernet driver stops working

We have this issue with several T400 and T500 series ThinkPads that the Intel ethernet driver stops working after a while. All this started to happen maybe a month ago. We have both 32- and 64-bit Windows 7 OSs.
Wired ethernet works ok first, but after a few hours or a day or two this yellow exclamation mark appears on the network icon and it says limited or no connectivity. Wired network stops working and there is nothing we can do to fix this other than reboot the computer. It doesn't even shut down properly, just says "Shutting down" forever and blinks the HDD led maybe once a second. So we have to force it and after booting everything is ok until the next time this happens.
When the network stops working, nothing can be done with the driver because everything just hangs. You cannot disable the connection or uninstall the adapter from Device Manager or anything. Unplugging the ethernet cable does not help either. There is nothing about this problem in the Event log other than about the symptoms of not having a network connection.
What could be the source of this problem? Do you have any ideas about how to diagnose this problem further? We have the newest driver and I have also tried the newest driver from Intel.

Go to Local Area Connection (Wired Intel adapter), Properties and the Configure button, in the Power Management Tab UNCHECK "Allow the Computer to turn off this device to save power".
Window7 does NOT always resolve IP and DHCP when it come out of sleep etc. All attempt to release/renew are in vain. I have seen this on various systems for some time. Occassionally a router reboot fixes it but most of the time is the PC. Frustrating but for Wired use this should always be disabled if you're using it a lot. Power savings is not in your best interest.
Let me know if that does it.

ITunes8 -- all optical drives stopped working

After installing iTunes 8, all my optical drives stopped working. Windows simply didn't recognize them. Device manager said they were missing. However the BIOS found them. Uninstalling iTunes8 fixed it.
However, like everyone else here, now I can't return to a previous version of iTunes because it refuses to recognize my library file (a .itl file).
Argg
What can I do, to either use an older version of iTunes, or fix this problem?

I tried the suggested fix on Apple's site (http://support.apple.com/kb/TS2372?viewlocale=en_US) but both my DVD drives remained invisible.
Then I tried the one at MS suggested by Adrian Kingsley-Hughes on his ZDNet blog (http://blogs.zdnet.com/hardware/?p=2600):
http://support.microsoft.com/kb/314060
Hooray! It worked! Not only have my drives reappeared, but I am burning a DVD right now using InfraRecorder.
Unfortunately, now I get a nasty message about missing registry data whenever I start iTunes, but I assume Apple will fix this problem in some future release. I'll have to live with it until then.
I spent hours on this today and almost ordered some new SATA drives, thinking the IDE controller on my mobo must have gone bad. I really appreciate the existence of Adrian's blog and other third party resources!
And I am very annoyed at Apple right now. Releasing software that breaks peoples' computers in a major way is not acceptable, IMHO. Leaving the bad software out there and posting fixes that don't work is even worse.
BTW, I am running XP Pro SP2. I have Logitech hardware and software installed, as well as a number of other USB devices (Treo, Canon printer and scanner, iPod) so (according to Adrian and other sources) I guess I was a likely victim.
Note that, having been burned before by new major releases of iTunes, I was cautious: I held off on installing iTunes 8 until the second release, hoping they'd have fixed any really bad bugs that showed up in the first release by then.
Silly me.

My macbook hard drive stopped working and I loaded another hard drive and can access time capsule but it doesn't show any of my old files and I don't understand why

My 7 year old macbook hard drive stopped working and I put in another hard drive but when I went to restore my information from airport time capsule it only shows today and nothing older. Help?

Did you do a TM backup after you installed the disk? It may write over the previous backup.. but it should actually start a new one.
Read the info about using migration.. see http://pondini.org/TM/Home.html
Or the Mac is probably looking at the backup as from a different computer.
See the details of how to use TM to restore to a different Mac.
Q17 here. http://pondini.org/TM/FAQ.html
I would read through 14-17 carefully.
You should be able to do a full recovery of the TM backup to a USB drive plugged into the computer.

Radeon display driver stopped working

Hi
I am running Win 8.1 x64 (up-to-date) on HP Pavillion 1322TX laptop. There are Intel HD Graphics 3000 and ATM Radeon HD 7450M two graphic cards as the device manager window. Recently I am getting blue screens and later message appear saying the ATM driver stopped working. I found many problems with this driver in the past as well. When I check the relevent page for my laptop model, there is no update since 2012. What the hell!
Can I update these two drivers seperately by getting updates from Intel and AMD sites?
Is there any update for catalyst control system (CCC) ?
When I try to update through the CCC or HP Support Assist, it is always no updates.
Can any one please advise me?
PS. I am fed up with HP and ATM, I wont go for HP again and never recommend for someone elese.
This question was solved.

Hi JSHLMS,
I see that you have some questions regarding the your switchable graphics. You will not want to use the drivers available from Intel and AMD because with switchable graphics it is the manufacturer of the notebook that configures the drivers. Intel and AMD provide a basic driver and HP configures for their notebooks. You can download the latest AMD software package which includes CCC here. I did some research and found Windows 8.1 versions of your drivers but as your model doesn't have specific drivers I can't guarantee that they will work. If these drivers don't work then I recommend downgrading back to Windows 8.
