Windows 7 Dolby Surround Sound Download

[Ping Weafer]

Windows10's Creators Update added support for Dolby Atmos positional sound. This includes two things: Support for Dolby Atmos hardware and virtual Dolby Atmos sound that works in any pair of headphones.

The Dolby Atmos for headphones feature is a bit weird. It appears in the standard Windows control panel as an option, but it requires a free trial or $14.99 purchase via the Windows Store before you can actually use it.

Traditional 5.1 or 7.1 surround sound uses 5 or 7 speaker channels, plus a subwoofer. When you watch a movie or play a game with surround sound, that movie or game is actually sending 6 or 8 separate channels of sound to your speakers.

Dolby Atmos is an improved type of surround sound. It isn't mixed into several separate channels; instead, sounds are mapped to virtual locations in 3D space, and that spatial data is sent to your speaker system. A Dolby Atmos-enabled receiver then uses specially calibrated speakers to position these sounds. Dolby Atmos systems may include ceiling-mounted speakers above you or speakers on the floor that bounce their sound off the ceiling, for example.

This feature requires Dolby Atmos-enabled hardware, notably a Dolby Atmos-enabled receiver. Microsoft also just added Dolby Atmos support to the Xbox One, and many Blu-ray discs include Dolby Atmos audio.

Windows 10's Creators Update also added a separate feature named "Dolby Atmos for headphones". This feature promises improved positional audio in any pair of headphones or earbuds. You don't need special Dolby Atmos headphones. It's a type of virtual surround sound built into Windows.

Really, this is a completely different feature that's only linked by Dolby's branding. True Dolby Atmos requires a hardware receiver and special speaker setup, while Dolby Atmos for headphones is a digital signal processor (DSP) that takes surround sound from your PC and mixes it to offer an improved positional sound experience in headphones.

Some games have already added support for Dolby Atmos for headphones. For example, Blizzard's Overwatch includes built-in Dolby Atmos support, and it works even if you're not running Windows 10's Creators Update. You can enable this feature from Options > Sound > Dolby Atmos for Headphones in Overwatch. Blizzard argues that Atmos offers an improved experience that allows you to more easily pinpoint where sounds are coming from in the game.

The app will guide you through setting this up. If you have Dolby Atmos receiver you want to use with your PC, select "With my home theater". If you want to use any pair of headphones, select "With my headphones".

If you select a home theater PC, you'll be given a link to enable the "Dolby Atmos for home theater" option in the Windows Sound settings control panel. After you do, the app will prompt you to calibrate your system. There's no additional purchase necessary for the home theater option---you just need the hardware.

If you select headphones, you'll be prompted to confirm your PC's sound hardware supports the Windows 10 spatial audio platform for headphones. Modern PCs should have sound drivers that support this feature, but you may be out of luck if you have a much older PC you've upgraded to Windows 10.

Once you've enabled the free trial, you'll be prompted to enable Dolby Atmos for headphones. Click the "Configure PC settings" button and then select "Dolby Atmos for headphones" in the Spatial sound format box.

This option actually appears in the properties window for your audio device even if you don't have the Dolby app installed. However, if you try to enable this feature without installing the app first, Windows will prompt you to install the Dolby Access app from the Windows Store first.

While the videos are impressive enough, you'll want to actually test Dolby Atmos by playing some PC games or watching some surround sound-enabled videos before paying for it and see if you can notice an appreciable difference. Some people say they notice an improvement, while others don't notice much of a difference. It likely depends on the games you're playing videos you're watching, too.

When testing Dolby Atmos, be sure to enable 5.1 or 7.1 surround sound in whatever game or application you use. The application will then produce surround sound, and Dolby Atmos will mix it to stereo sound for your headset.

Windows 10's Creators Update also offers a free "Windows Sonic for Headphones" option you can enable instead of Dolby Atmos. Just right-click the speaker icon in your system tray, select "Playback Devices", click your playback device, and click "Properties". On the Spatial sound tab, select "Windows Sonic for Headphones".

You may want to test this feature to see how it compares to Dolby Atmos for Headphones in your games and videos. We've seen some people say it doesn't work quite as well as the Dolby Atmos option in their experience, but we've also seen some people say they don't notice much of a difference.

It seems Microsoft or Realtek or the A/V industry in general is making it harder and harder for me to get 5.1 surround sound out of my computer. It seems some update within the past month or two has broken it, and I can't get it working satisfactorily again. I have done lots of googling and tried lots of things. I'm going to list what I think I know and ask questions that maybe some folks on here will be able to answer. Thanks in advance for all help and advice!

Setup:

HTPC used for Gaming / TV / DVR (AMD based with AMD graphics card)

Windows 10 Home, build 1909

LG WebOS TV

Yamaha RX-V2400 Receiver (pre-dates HDMI)

HDMI cable (active) to the TV

Optical Cable from PC to Receiver

Optical Cable from TV to Receiver

Usage notes:

*If I use the HDMI output through the TV to the Receiver, I don't get 5.1 sound at the receiver. It seems this is typical for TVs. I haven't found a setting to tell the TV to output a PCM bitstream.

*I get occasional dropouts of audio using this configuration. Short dropouts, just a fraction of a second, but very annoying. Don't know what is causing this and don't know how to debug. It doesn't happen to the picture, just the audio.

*Because of the problems above I use the Realtek Digital Optical output primarily. After whatever update got pushed, it is now only outputting 2 channels to the receiver. I tried all bit and frequency settings in the configuration. I tried old and new Realtek drivers and generic windows HD Audio device drivers.

*I tried the "patched" Realtek drivers that I read about on other forums. These give the option to select Dolby Digital Live (5.1) on the advanced tab of the properties instead of something like 2channel 24bit 96000hz. This worked sometimes. Playing MP4 movies through Emby Theater worked great. Playing videos on Youtube through the web browser or playing a computer game had lots of annoying audio dropouts. Fraction of a second type droupouts. Switching the settings around for whether I am using Emby or playing a game is not convenient from the couch. Does anyone know if this kind of setting change could be scripted or assigned to a macro?

Am I missing anything obvious that could make this work?

If I buy a PCIe plug in sound card or USB connected sound card with an optical output, will this solve my problem?

Or do I really need to buy a new receiver with HDMI input and switching capability? I really don't want to get on the audio component upgrade train again. I was peeved when 2 years after I dropped big bucks on a 5.1 receiver the industry went to component video and I needed to get a new receiver to handle that. I have so far refused to upgrade again for HDMI, but if this is forcing me, I may have to reluctantly give in.

If I hit the configure button, it still shows "Stereo" as the only speaker configuration option. However, if you click the properties button and select the supported formats tab, it shows DTS Audio and Dolby Digital under "Encoded Formats" indicating the system at least recognizes this device can support multi channel audio. On the Advanced tab, you can select the default quality and *this is important* check the Exclusive Mode check boxes. I did not get DD out when these boxes were unchecked. I assume because Windows or the driver can't merge sounds from multiple apps and output them in a DD encoded stream, only a 2 channel PCM. This is probably why there is this big driver mess in the first place.
