Making Audio Enhancers Work on Windows

[chris189]

Thank you but still the Advanced Options are still greyed out. Do I need a modded driver or something to get it to work?

When you installed APO Driver, did you select Dolby Digital Plus?
If not, use maintenance driver to select Dolby Digital Plus (it is the selected one in the picture).

 

[chris189]

Cool! Thank you so much. It's working now. So should I go play a game to test it?

PS - Even know it shows up as normal in the Advanced Tab. My receiver reports PCM 2 Channel mode still.

If I go to Speakers Properties, and try to apply Dolby Digital I get an error message "Format not support by the device".

I don't get it?

You should only apply on digital endpoint.
You applied on speaker endpoint.

 

[chris189]

Thank you for you help buddy. I did only the digital endpoint & it showed up in both.

It's not working on the Cmedia CM6206-LX USB.

Dolby Digital test sound does come out on supported formats tab?

 

[chris189]

@CityCultivator Only stereo though, Left Channel & Right Channel on the test.

@CityCultivator When I do a Test I get a pop & then only the left & right channel chime from the test.

If I understand well, when you click on Test when selecting Dolby Digital on the supported Formats tab, you are getting Stereo?

Yes, that's correct. Still getting pcm 2 channel stereo from my lg bh6720s.

OK, that appears something beyond the USB device is wrong. This supported formats page test button does a bitstreaming of a preencoded Dolby Digital signal; something is decoding the signal to PCM beyond the USB device, or something might be misconfigured on the receiver.

 

[chris189]

These are my settings on the receiver.

What receiver/htib you are using?

And to connect, is it a direct connection from the usb device optical out to the htib receiver optical in?
Do recheck the speaker setup settings, if it is properly 5.1.

 

[chris189]

Yes, it's all setup correctly. If I watch a Dolby Digital 5.1 or DTS 5.1, the bitstream is activated. However the Dolby Digital Plus is not activating the DD3/2.1 symbol on my receiver.

On that page you were supposed to get the Dolby Digital in the advanced tab; I don't see it.
Also There is usually a Dolby tab present.

See as you did on your speaker endpoint.

FX Configurator has applied on the wrong endpoint. Guess it is a bug in FX Configurator.
Can you provide a list of all endpoints you can see?

Not all drivers allow multichannel out from SPDIF. If the device has restricted input (2 channels), even with an encoder, you still get 2 channels.
I tried to write a driver for USB, and I found that its OEM locked to 2 channels, and its not easy- not possible to work around it.

You will probably need to modify the driver to allow 6 pcm channels in, to be processed by Dolby.
Edit: Pretty sure that says DTS 3/2.1 (5.1), still displays with empty channels.

----

Edit 2, I might have an idea with VAC passthrough to SPDIF, if you transcode before SPDIF, then SPDIF will play all channels.
Not all SPDIF's can support multichannel transcoding (6 pcm in > 6 digital out).

 

[chris189]

@CityCultivator the reason why the dolby tab isn't present is because i uninstalled it because it wasn't working.

@Ferather
SOFTWARE OPTIONS

• Dolby® Digital Live / DTS Connect Options (CM6208 / CM6209) I have the CM6206-LX. Unless you can mod the driver?
• USB Audio,PCIe audio,USB audio ic,USB sound chip--C-Media Electronics, Inc. (cmedia.com.tw)
• Download C-Media CM6206-LX USB Audio DAC Driver 1.04 for Windows 8 (softpedia.com)

 

[Ferather]

So you are receiving 5.1 (DTS and Dolby is coming in as 6 channels, but only 2 have audio). I just tried VAC and it does output 6 channels to my SPDIF, however it already accepts 6 channels of PCM.
I was intending to modify it to add the encoder to it, and then send that stream to SPDIF already encoded, but it will require me to rewrite the app

You have (probably): 6 Channel PCM > SPDIF, restricted to 2 channels > Encoder (only 2 channels) > 6 channels out, only 2 populated.
What you want: 6 Channel PCM > SPDIF, no restrictions > Encoder > 6 channels out.

Alternative: 6 Channel PCM > Virtual device > Encoder > Passthrough to SPDIF. < Clever and some money to made there (app).

Some media players such as PotPlayer can transcode audio to DTS (multi-channel), but its within the player.

@Ferather
When I watch Dolby Digital 5.1 & DTS 5.1 movies, I get true surround sound out of all 5.1 channels.

When I activate Dolby Digital in the Advanced Digital Output properties, I get some scratching & popping & a chime from left channel & right channel. So only Stereo Dolby Digital (Live) from SPDIF.

If there is anything you can do, that would be awesome? Unless its unsupported in hardware?

 

[Ferather]

"When I watch Dolby Digital 5.1 & DTS 5.1 movies, I get true surround sound out of all 5.1 channels." < Correct, its already encoded with all channels present.
Have you tried an upmixer? Try this app and guide, if you are getting noise on the extra channels that's interesting, still might not work.

The problem is the hardware SPDIF setup is restricting the input for the encoder to 2 channels.
If you took a 5.1 PCM track, and encoded it DTS, then sent that, you get 5.1.

This is why I was going to try VAC, it would have took the 6 PCM and encoded it to DTS-DD, then send that, like your first response.

----

The best you can do at the moment would be transcode (to re-encode, from PCM to DTS) via PotPlayer (media only).

@Ferather Thank you. So its a hardware limitation? Thats too bad. I don't really want to upmix, thats like virtual surround sound.

I know we've been over this already but I tested again the "test button" in Supported Formats tab & I hear everything out of all 5.1 channels on Dolby Digital & DTS. On the Advanced tab "Default Format" of Dolby Digital, I only get left channel right channel on the test. So I guess this is a hardware limitation?

 

[Ferather]

Sounds like it , or drivers.

When you tested on advanced tab,

1. Were you able to select Dolby Digital?
2. If yes, were you able to hear anything (in front left, front right)?

 

[Ferather]

He only gets stereo, left right with it selected, the driver or hardware is either downmixing multichannel to stereo, or dropping the other channels, pre-encoder, the encoder only receives 2 channels.
