Realtek via optical no 5.1 (xaudio problem)

[Xorloth]

Just installed WIndows 10 update 1511 (threshold 2) which at last enabled 5.1 through optical.

Movies works nicely and so does Dying light. When I turn around in that game the sound from for example firecrackers moves from speaker to speaker. So it's clearly working for me finally.


But what about Fallout 4? Is there any setting I can change?

I threw a couple of grenades and turned around but only audio from front speakers.

I can't imagine Fallout 4 being unable to produce 5.1

[Xorloth]

Does fallout output 5.1sound at all?

EDIT: Yeah it does! Analog multi channel works.

I too don't have 5.1 though my DTS Interactive (digital out). But I have it with my 5.1 analogue. I was so excited that WIN 10 finally fixed the DTS (and DD LIVE) issue. My other games work fine now, but this one still outputs in 2.1.

[Xorloth]

Glad to hear that someone else got the same issue. But I wonder how low priority this really is for Bethesda and if they even are aware.

[mallow81]

I did some more tests...
A few games work fine like Skyrim and a few others. But some games don't (that used to) Like Shadow of Mordor.
I don't think it's Fallout 4 that is the problem. I think it is still a problem with the DD Live and DTS Interactive in Win 10.

I got Far Cry 3, Borderlands 2 and even Fallout 3 to work nicely.

But you could be right. I should read up on what people at the microsoft thread have concluded.

EDIT:
I decided to plug in the old X-FI Titanium from my old computer and both Dolby Digital Live and DTS Interactive worked without a problem in Fallout 4.

So this could be a problem with Fallout 4 and realtek DTS or Windows 10 with Realtek driver

@mallow81: Do you also have a Realtek chip with DTS Interactive?

That's exactly correct. RelalTek chip with DTS Interactive.
I wonder if updating the drivers would help... I'll check it out. Maybe together we'll solve this thing.
So you used a PCIE add on sound board with Optical Out with DDLive and it got correct positional 5.1 with Fallout4? Then I agree, that it is most likely the RealTeck with Win 10.

I remember I had a surround sound issue with Skyrim and someone found a solution that worked for me which is if you are using Realtek, disable the Full-Range Speakers in the Speaker Configuration.

That doesn't change anything if you're using Optical Out. I have 5.1 Roccat Kave XTD for my "speakers" (analog out) and they work perfectly with Fallout4. But the Optical out going to my reciever doesn't work with this game.
I just uninstalled all audio drivers and upudated to the most recent by RealTek. No change in the situation. Then tried again with the newest drivers from Windows Update. Still no change.

i also using win10 and have that problem with dts and in order to make my 5.1 working i need to use 7.1 what is i bit idk strange

[Xorloth]

Sorry for replying so late. I didn't get any notifications about this or mistakenly marked this as read.

Yeah I plugged in my pcie x-fi but that's creative so it works without issues.

This is a problem with xaudio and realtek using uptical out has has been going on since windows 7. At the moment the only solution seems to be to hexedit lot's of xaudio*.dll files in the system 32 folder. So it's not something everyone should do.

I haven't bothered editing the dll files since I'm using my x-fi at the moment. But it seems there are pre edited files you can just copy paste.

Let's see if I can find the link to the workaround:

Here is an old thread on microsofts forums from 2012 about it:
http://answers.microsoft.com/en-us/windows/forum/windows_7-gaming/has-xaudio2-been-fixed-for-dolby-digital-yet/304c4dc9-ea55-48f4-b08b-9946700763fe?rtAction=1400505261779&auth=1

As you can see. This is not something that only has to do with Fallout 4. So I guess Bethesda aint gonna fix this since microsoft has to do it.


Oh and by using realteks own drivers the DDLive and DTS Interactive may not work since they are not licensed. You have to download the drivers from your mobo maker or windows update, I think.

[Mine_buddy]

u just fix it uninstall the realtek driver and let windows instal the drivers

[liter cola]

I'm using a sound blaster x-fi to send SPDIF to my receiver and also only getting stereo out of the front speakers. Has anyone found a solution yet outside of dll edits?

[Xorloth]

My x-fi works fine in 5.1 through spdif. Have you updated to the latest windows 10 drivers from their website and updated windows 10 to November update 1511? You may need to reinstall the audio drivers after the windows update.

[liter cola]

Thanks for the reply, I'm on Windows 7, have been holding off since it's actually a Mac running boot camp and not supported. I decided to buy a new PC, that solved the problem!

[Absolutely]

After I click play, there is surround sound for the first movie clip that plays. Goes away in game using digital optical.

This been fixed yet?
