Dolby Home Theatre 4

I just noticed on my w540 that the Dolby Home Theatre v4 doesnt do anything? Changing the settings does nothing to the sound when playing music. Should it not do something?
Removed and reinstalled the drivers, and nothing. Using Windows 8.1
I can see within the sound settings that dolby digital plus seems to be installed, and I can toggle it on and off, leading to a change in sound quality. However, home theatre does nothing. Any thoughts anyone?

Hi pete_123
Does the audio characteristics not change even if you switch in between Movie, Music, Games or Custom? I have the new Dolby Digital Home Theater installed on my 11s and still under testing, In my opinion, the new Dolby Digital HT and AA has less feature set and the EQ does not seems to be working. (It somehow works, but does not allow you to view your settings).

Dolby Home Theatre v4 not working with windows 8.1

Hello,
I have recently downloaded and updated my laptop to windows 8.1 and suddenly dolby home theatre v4 has stopped working. Battlefield 3 has also begun to crash randomly. Could you please help me?
I have a Lenovo ideapad U410 intel core i5 3337U 1.8GHz Processor, 8GB RAM, 1TB HDD.
thank you
Adam

hi Adam,
Welcome to the Lenovo Forums.
Can you try the following:
1. Uninstall Conexant HD Audio and Dolby Advanced Audio v2 (if applicable) under the Control Panel > Programs
2. Reboot the PC and re-install the Conexant Audio Driver for Windows 8.1 (this contains the sound driver+dolby)
Conexant Audio Driver
      Windows 8.1  (32-bit, 64-bit)
     Version 8.65.3.53
After installing, reboot the PC and observe.
As for Battlefield 3, have you tried running the game in compatibility mode? If you're getting Direct-X errors, check this thread.

W10 will update drivers automatically so if we attempt to go back to older drivers that worked (e.g. in Windows 8.1) surely the software will only work for a matter of time before Windows downloads an updated (and uncompatible) driver and overrides it? I had the same issue on my V3-571, along with massively increased boot up issues. After a week of trying to fix a number of issues I went back to Windows 8.1 because I knew that everything would work flawlessly. I can now use Dolby Home Theatre v4 and my laptop is back to booting up in sub 15 seconds again.

Dolby Home Theatre missing after Win 7 Pro x64 factory restore

Hi,
I restored my T430s to the factory default Win 7 Pro x64 .
However, Dolby Home Theatre cannot be found.
Where do I download it? It does not appear in the driver matrix for the T430s.
Thanks!
Solved!

I had this Dolby tool and uninstalled it :-) I think Dolby tool is part of AUDIO driver install. Download the AUDIO package for your laptop and install it. Dolby tool appears in 'Programs and Features' also.

Was sol ich jetzt nun machen? Meldung erscheint immer wieder.
Danke für eure Hilfe.

Hallo Dibaer,
der offiziell von Lenovo für Windows 7 (32/64 Bit) und Windows 8 (64Bit) veröffentlichte Treiber liegt in Version 6.0.1.6823 vor:

Wir können kein Problem bestätigen, solang du andere Treiber als die vom Hersteller veröffentlichten (und getesteten) nutzt.

U310, Bluetooth, Dolby home theatre and Windows 8.1 update

Brand new U310. Two situations.
1. Installed Win 8.1 uodate. Bluetooth does not detect nor is detected by my smartphone.
The action center in control panel has these messages:
Reinstall Intel Bluetooth Wireless High SpeedTo use Intel Bluetooth Wireless High Speed with this version of Windows, you must reinstall it using the original installation media or download files. If you're unable to locate the media or files, contact Intel, the manufacturer of Intel Bluetooth Wireless High Speed for more info.
and:
Reinstall Intel Proset Wireless/BluetoothTo use Intel Proset Wireless/Bluetooth with this version of Windows, you must reinstall it using the original installation media or download files. If you're unable to locate the media or files, contact Intel Corporation, the manufacturer of Intel Proset Wireless/Bluetooth for more info.
Tap or click to go online to the Intel Corporation website for more info and support options
2. Error message on reboot: Unable to start the Dolby audio driver. Please restart the computer or reinstall the driver if the problem persists. There is not any action center messages regarding Dolby.
In both situations the device manager reports drivers are all working properly. There is not any yellow warning triangles visible.
If someone can identify the correct driver/software I can download and install that would be great. Telephone support was difficult to understand and thus no help.
Thanks,
Don

These are the Win 8.1 drivers that you mentioned. All you have to do is to click "Support: Drivers and Download" and select "Drivers and Software" and select the model of your unit. Under operating system select Win 8.1. Uninstall with Delete option the present drivers before installing the new drivers.

Can't install Dolby Home Theater after upgrading to windows 10

HI, I have an Acer v3 572g. I upgraded from win 8.1 to win 10. Everything is working fine except that the upgrading process completely removed the Dolby Home Theatre application and its drivers and automatically installed the Realtek high definition drivers, after I found out about it, I tried some tips I found online , this is what I did: Downloaded the audio drivers from the Acer website, uninstalled the default audio drivers then, I installed the acer drivers followed the installation process restarted my computer after that, I try to run the DolbyHomeTheater installer found in the PCEE4 folder but after I open the setup file it says: DHT cannot be installed. it doesn't explain why it cannot be installed whatsoever. I can't get this app installed no matter what I do, I've tried different things like installing and uninstalling multiple times, running the setup in compability mode... I don't know what to do now Any help will be very appreciated.

Hi! Thanks for your reply, I did exactly what you suggested but it didn't work for me. I'm able to install the audio drivers but when I try to run the Dolby Home Theater setup, it gives the same error "DHT cannot be installed" I now tried running the setup in troubleshoot compability mode it says: "Settings applied: Windows compability mode: Skip version check.Then, I click on test program but get the "DHT cannot be installed" error.After that, Windows compabilty troubleshoot asks me whether the problem is fixed or not, I click "no" then it says: "issues found: Incompatible program: DolbyHomeTheater is incompatible." But the odd thing is I'm able to install Dolby Advanced Audio v2 and not DHT v4,
I don't know if this is an issue with Windows 10 and Dolby, Acer or both are working on it or something went wrong during the upgrading process...

Macbook 2008 sound to Home Theatre System which only has optical audio.

Trying to connect my macbook (2008) to panasonic home theatre system which only has optical audio. Tried using toslink optical audio cable with 3.5mm jack converter but still no sound, any ideas please? Thanks

If I understand what you are saying then yes you are correct. If you want the sound from your tv to come out of your home theatre amplifier run an optical caple from the TV out to one of the inputs on your receiver. Then select that source when you want to listen to the tv. In order to get 5.1 sound though the program source will have to be broadcast in dolby digital. Other wise it will most likely be dolby pro logig or stereo depending on how your receiver is set up.
It will probably also output sound for your blu ray player as well through the tv because hdmi carries audio to your tv. However the best possible sound will come from hooking the hdmi cable directly up to your receiver and selecting that source during dvd playback. Which is the way you have it if I understand correctly.

Routing HDTV Sound to Home Theatre Sound Sound

Please confirm that the optimum cabling to obtain "5.1 surround sound" from my Samsung LN650 HDTV TV source is using a digital optical cable? I can use dig optical or a coax connection. I assume I route this cable from my HDTV digital optical output to my receiver (Pioneer VSX-1019AH) optical input?
Currently TV audio only comes out thru HDTV speakers.
Based I what I have read, I believe once I put this connection in, all I have to do is select the appropriate "source" on my receiver (in this case TV)?
Existing routing on my system is as follows:
Coax from Antenna to HDTV Antenna Input.
HDMI Cable output from Receiver to HDTV HDMI input.
Thanks
PS. My Sony BD BDP 350S is routed to receiver via HDMI cable and I get surround sound from BD when I select BD as source on receiver..

How to connect Apple TV to DVD blu-ray home theatre

Hi guys, I am planning to buy Apple TV2 and I was wondering is there setup guide for connecting to HDTV and home theatre system. I currently have LG HDTV and LG DVD Blu-ray Home Theatre. They are connected with HDMI 1.3 cable and I had to get optical cable to get sound from TV to Home theatre.
How is Apple TV fits into that? I have 1 HDMI slot free on TV and 2 HDMI inputs on DVD system.
I was thinking just to connect Apple TV to DVD via HDMI? Would that put sound on home theatre system?
Thank you in advance.
ddrasko

You have read home theatre manual about playing sound from external device.
You doesn't need to connect home theatre to tv at all as you have get video from apple tv.
Connect video output from apple tv to tv(may carry sound along) and optical cable from apple tv to home theatre.
That will do. You can mute sound of tv(in case hdmi carry sound along) or using other function(on samsung ) and hear from home theatre sound from speakers.

Mac Mini as Home Theatre (advice please)

Hi There,
I am considering a Mac Mini to connect to my TV as a Home Theatre device. I just found out that the latest model has no optical drive & so that is a real blow to me as it is a very important factor.
I have checked the older models & it seems the mid-2010 model might have what I need.
It would be great if someone could confirm that model will have what I need...
1) Must play PAL DVD & NTSC DVD (region2) directly. (My PS3 only plays NTSC, my xbox360 has died)
2) Must have bluetooth - either for trackpad or PS3 controller (i beleive snow leopard has native PS3 controller support)
3) Must have full HDMI output (audio+video)
4) Wireless would be best, but LAN connection is fine.
5) Must be a small device that can easily be moved from room-to-room.
6) Having a decent web browser capable of using Megavideo etc, would be big bonus.
With no optical drive, it would mean streaming a disc from my iMac but this inconveinience makes the Mini's price tag unviable for me, since playing these DVD's is the primary reason to buy.
I could of course save a lot of money & buy a region free dvd player, but i thought with the other benefits of web browser on tv it would be the ultimate solution.
How about Apple TV? Thats $99 & would stream. But will it stream a DVD from the iMac? & does it have a web browser?
For $99 the compromise would be worth it.
Although as I live in Japan & am originally from UK - Netflix etc is impossible for me.
Thanks for any advice or sugestions.

EG: If you are in USA (region1) & you insert a region 2 disc you will not be able to play it unless you change the region lock. You can do that, but only 5 times ever & then you will be locked to that region forever.
I dont know if this applies to laptops, even more dumb if it does, because of course in business you may need to travel to many regions with your job.
It does. It even applies to Apple's external dvd drive for the Airbook. Apple is mad to go along with the DVD cartel on this. It is not uncommon for people to have DVDs from 3 or more regions. It is simply NOT GOOD ENOUGH that their customers have to resort to workarounds like:
* buying extra DVD drives
* finding some other software to play DVDs
* various hacks to reset the region change count
* altering the firmware on the DVD drive (voiding warranty and risking damage to drive)
Basically, wasting a lot of time mucking around, just so that they can play a bloody dvd. Get your act together Apple, and show some respect for people who hand you bucket loads of cash to buy a product that is supposed to just work, like your marketing hype says it should.
This policy is imposed by the movie studios on hardware makers. However a lot of hardware makers now ignore this insanity. Unfortunately Apple have chosen to obey this.
To show you the level of insanity, Sony are one of the big Movie Studios, Sony of course also make DVD players. Guess what, their home DVD players are able to play multiple regions. So even Sony at least in part think DVD regions are nuts.
On Blu-Rays there is also a similar Region protection scheme. All the resellers think it is just as stupid as the DVD region scheme. In fact resellers make a specific point of advertising titles that are region free as region free (not all titles enforce this on Blu-Ray). If having a title region free is regarded as means of increasing legal sales by resellers, clearly this means region protection is harming sales.
Movie Studio = Moron. QED

Mac Mini Home Theatre PC + Lion = Big Bag of Hurt

I have a mac mini (2010) connected via HDMI to a switcher and on to either a TV or projector. The TV happens to be on a wall 90° to the projector screen. The audio is also wired via toslink/optical cable to the AV amplifier. The main speakers are aligned with the projection setup so its nice to have the TV sound come from the TV directly sometimes, even though the quality is dreadful compared to the main speakers (as opposed to rich sound coming from only the left side).
Running under Snow Leopard was fine - just switch the audio out from the HDMI to the Optical out at will (as one would expect through the sound output control panel).
Unfortunately I thought it would be cool to update to Lion to have a trackpad rather than the mouse on the coffee table. Bad idea!
Under 10.7.1 it all seemed to be working OK. Sound from main speakers, picture over HDMI on TV or projector. Sweet. Then I tried to change to the TV's speakers via the control panel. Nothing works. Click on either "optical out" or "Panasonic HDMI" and nothing changes, the audio keeps coming through the amplifier to the main speakers. Oh, well, the TV's sound was crap anyway, I could live with this at a push.
Update to 10.7.3. Whoops. Now the sound only comes out through the HDMI cable to the television. Permanently. Again, choosing either option in the control panel has no effect. Apple seems to have hardwired it this way and those options are an illusion. Now, I want to watch a movie - ZERO sound! The projector has no speaker, but apple is sending the audio there along the hdmi and I have no way of routing it to the Toslink cable anymore. Total train smash!! Silent movies - whoo hoo. Fail.
Annoyingly, this isn't a limitation of the hardware at all (it worked perfectly as expected in Snow Leopard) - its obviously a conscious decision. Or no one at apple bothers to test their stuff properly any more. All suggestions summarised - get new hardware - either new AV amplifier which accepts hdmi or extra cables to feed audio back from the TV to the amp!!?? Jeez. It used to work perfectly already without that.
Oh well, restoring to Snow Leopard as I type. Will have to find another use for that magic trackpad I stupidly bought on Monday. So if you have a Mac Mini Home Theatre PC and you need the options on routing video and audio separately, stay away from Lion!

You didn't need Lion in the first place for the track pad:
System Requirements
Bluetooth-enabled Mac computer
Two AA batteries (included)
OS X Snow Leopard v10.6.4 or later
I was using one with my 2010 Mini before Lion in my
HTPC setup.

How do I stream iTunes content to my home theatre using any combination of a MacBook Pro, an iPhone 4s, and a PS3 using only a LOCAL network?

I have found many solutions to this problem assuming home internet access, but I only have access to the internet via my iPhone. I do not want online capability in my PS3. All I want to be able to do is control iTunes on my MacBook, and hear/view the content on my home theatre. I would prefer to use my iPhone as the remote for iTunes, and do not want to add the monthly cost of home internet to this equation. I do not require access to anything on my MacBook except iTunes in this application. I would prefer to use iTunes and stream to my home theatre, as opposed to setting up my MacBook as a media server and using the PS3 interface. Is this possible? Can I accomplish this goal using a local network? Can I create a wifi network on my MacBook to do this, or do I need a router? I am looking to spend as little as possible on this project, as I plan on moving to a more urban area soon, and will be buying Apple TV and subscribing to home internet service when this happens.

Get an AirPort Express. It has an audio out which you can connect to the line-in on your home theatre system. All the other devices will talk to the AirPort Express and stream content to it via wi-fi.
