Any Realtek users? PROBLEM SOLVED - SURROUND WORKS
THE SOLUTION IS AT THE BOTTOM OF THE MESSAGE

I have some problems with my Realtek audio - it doesn't work properly in Doom 3 BFG. Need help and advice.

I have a Realtek HD Audio (ALC889) connected to my 5.1 receiver via coaxial digital output (labelled as optical in Sound options in Windows).

The game detects my sound hardware as supporting 2 channels only. However, 5.1 works great in other games and films.

Fresh drivers don't help.

Does anyone have similar problems???

I have read that Realtek users encountered almost the same problem with CoD: Black Ops.

Can my x64 system be the cause?

Thanks in advance.


THE SOLUTION (quite easy, just detailed):

1. Find the XAudio dll files in the WINDOWS folder (you may use the Search thing);

2. If you are using an x64 system, the files may be 'paired', for example: you have one XAudio2_0.dll located in System32 folder and another one located in SysWOW64;

3. Copy the files from both the folders in a safe place and put them in the folders that would let you distinguish the files from System32 and SysWOW64. These files will be the backup, DON'T OVERWRITE THEM in future!

4. Make another set of copies, you will edit them;

So, now you have one folder with the backup files that are divided into two groups regarding their original locations and another folder with the same set of copies for editing - the folder where the work will take place.

5. Get an HEX editor if you haven't got one yet. I found XVI HEX editor very convenient for such kind of task.

6. Open one of the files that are supposed to be edited in the HEX editor and find there the line: 4D069FF12C08274EBC736882A1BB8E4C00000000

7. OVERWRITE this line with this one: 260E87E4C53CD24CBA46CA0A9A70ED0400000000

8. Save the changes in the same file.

9. Repeat the 6, 7, 8 for the rest of the files.

10. Copy the edited files to their original directories in the WINDOWS folder.

11. I'd recommend you restarting your PC before trying the game.

12. Remember to switch on the subwoofer ;)

Enjoy :)

I want to get 5.1 sound through the digital output but the game detects the hardware as 2-channel.

Are you sure? The BFG Edition has fixed surround sound. People who have Realtek DO have 5.1 but via analogue outputs, not digital. I think, it is not about EAX.

I would be curious to know what games are outputting 5.1 sound on optical cable without any special software
Because S/PDIF just support 2 PCM channels, surround require dolby or DTS encoding

Either you didn't understand that I use a coaxial cable or I didn't understand YOUR message. =)

Coaxial, my bad. It's still S/PDIF after all, isn't it?
How could you pass 6 channels trough it in other games?

Well, S/PDIF does support DD and DTS according to Wikipedia and my experience. In digital form, of course.

Well, sure.
Though the OP claims he can get 5.1 in other games w/o nothing of similar

If I understand properly, you mean that in other games I have surround working not using DD or DTS, right? Other games are working fine using DD surround, that's what I wanted to say in the original message.

Oh, now it makes sense :D
Sorry. And I didn't recognized *you* were the OP

Besides, I'm quite sure this is your problem

WOW man THANK YOU!!! The solution exists and WORKS!!! I thought I had to switch to WinXP to try the surround sound. Thank you again!

Now I want to tell everyone with the same problem about the solution. =)

P.S.: wow that wicked rumble of machinery coming from my subwoofer! Here the fresh Doom3 experience comes! =D

I would be actually curious to know what happens on winXP, since you would have directsound in the end of the sound chain, and not XAudio..

Though glad it worked :)

Sorry, didn't mention the whole 'XP-plan': besides the Realtek chip in the motherboard, I have a Sound Blaster 5.1 LIVE! that supports Doom 3's surround sound but I needed to install XP to install proper driver for the card to work properly.

As I said, I'd like to know how things work there.

Though, live! works just fine with Vista, 7 and even 8 for the record.
Only, it works flawlessly only up to 2 GB of RAM
Otherwise just use these drivers (EAX don't work though)
