I have an MSI B550M Mortar motherboard and am currently running Windows 7. Everything works fine except I can't get the Realtek audio working to use with my S/PDIF optical cable.

Using Realtek's latest (2.82) drivers I was able to get the Realtek HD Audio Manager installed, but I still was not able to hear any audio come out of the speakers and I have not been able to see "5.1 channels" or see any Dolby Digital Live/DTS options anywhere.

I have tried several solutions including 2.81 drivers which apparently worked for another user with a B550 chipset (but they are running Windows 10 and I'm on 7).

When I try to install 2.80 or 2.81 drivers I see an error message at the end of the installation:

Code:
Realtek High Definition Audio Driver - InstallShield Wizard
---------------------------
Install Realtek HD Audio Driver Failure !!
 [Error Code : -0001]

When I install the latest 2.82 drivers there is no error but there is no 5.1 or DTS/DDL options and I still don't have sound via optical cable.

In all cases, the driver displayed in Device Manager remains as "High Definition Audio Device" by Microsoft.

Any suggestions would be much appreciated. Thank you.

Well, this error can indicate the lack of the driver information file (INF), the lack of driver installation files, which are usually available to INF or the absence of Microsoft's WHQL signature or any other digital signature eligible for such.

Firstly thank you very much for replying.

Should I try installing with Digital Signature Enforcement disabled?

Moreover, should the 2.80 or 2.81 version drivers even work for my hardware (the ALC1200)?

I recommend you to install R2.82 directly from the Realtek website

Trying that gives the same error:
1618871480915.png



I can avoid the error if I use Device Manager and choose "Uninstall" of the High Definition Audio Device immediately before I start the Realtek installation.

When I do that, the error does not occur.

However even then the device does not work, and when I reboot, the device is installed as "High Definition Audio Device" with Microsoft driver again!

Is there a way I can remove this Microsoft driver completely? It seems to be always re-installing itself even after I uninstall it.

Thanks

Send the hardware ID of your audio chip here. It may also be a hardware ID not found in the driver base.

That one installed OK, and shows the correct version number in the Realtek HD Audio Manager, however I still don't hear any sound from the speakers, and don't have options for 5.1 channels or DTS/Dolby Digital.

Now, open the task manager, end the audiodg.exe process and the Windows Audio (Audiosrv) and Windows Audio Endpoint Builder (AudioEndpointBuilder) services, RESPECTIVELY, open the tablet that I will leave attached and extract the DLL to "%systemroot%\System32". Once this is done, restart your computer.

That has changed the Realtek HD Audio Manager screen a bit. I can now see DTS/Dolby logos, but still no sound is being produced from the speakers.

My speakers also have a "Decode" light which lights up when digital audio is being sent to them; this light does not switch on either.

I have tried using the "Test" options in the Windows Sound dialog and have also tried playing a film with DTS audio, and still nothing.

There are still no "5.1 channel" options in the sound dialog either.

Oh, I have a "Dolby" tab in the sound properties now:

1618875673906.png


Still no 5.1 options:

I also received this warning when I tried to open the sound properties:

Exactly the same results I'm afraid.

Also, this may be useless information, but I was trying out other versions of drivers and found one from a slightly older motherboard with the same Realtek codec (ALC1200) with "official" Windows 7 drivers: https://download.msi.com/dvr_exe/mb/realtek_nahimic_audio.zip

I downloaded these, patched them using the old "realtek.hd.sound.driver-patch.exe" tool, then installed them (after uninstalling the drivers you had previously sent).

Interestingly, they installed the generic-looking Realtek HD Audio Manager and not the MSI-branded one from my screenshots. DTS logos etc. were present, and DTS/Dolby 5.1 options were present in the Windows sound dialog box. However, nothing worked - still no audio, and no "Decode" light on my speakers.


Anyway, I'm back using the drivers you sent, and the modded .dll you sent as well. If you have more suggestions please continue :)

Quick update: I suspect the onboard audio itself may be faulty. I can't see a red light coming from the optical out port.

I'm going to replace the board and/or try a discrete sound card.

Will update in 1-2 weeks.

OK, I replaced the motherboard with an identical one and the optical port actually works - I can hear sound now.

However I still only see "2 channel" modes when selecting a "Default Format", even when I am running the modified RltkAPO64.dll driver which @Alan Finotty provided above.

I can see the DTS and Dolby buttons in the Realtek control panel, but no matter if I use them or not, my receiver is only receiving stereo (2 channel) sound and not 5.1.

Any idea how I can enable 5.1 formats, please?

Finally got this working with a driver from forum user @dvojinov, from this post: https://www.techpowerup.com/forums/...-live-and-dts-interactive.193148/post-3742663

I'm not sure how his driver differs from the modified drivers provided by @Alan Finotty but I'm just glad it works. I notice that the Realtek HD Audio control panel is the "generic" blue one with just a small MSI logo in the corner. I also notice that the audio codec is now showing as ALCB00 whatever that means:
1619321319164.png


The filename of the driver I used is realtek_hda_6.0.1.8272_dts_ddl_experimental.zip and currently it's available from here: http://sharemods.com/dmwlfqpe2h66/Realtek_HDA_6.0.1.8272_DTS_DDL_experimental.zip.html

To summarise, the procedure which got this working on my MSI B550M Mortar motherboard with Realtek ALC1200 codec on Windows 7 was:

1. Firstly, be aware that I tried about 20 different Realtek HD audio driver packages including R267, R270, R280, R281, R282, and none of these worked.
2. Each time I changed drivers I would uninstall the Realtek package via Control Panel, and then reboot.
3. I would then use DriverStoreExplorer to remove any sign of leftover drivers and reboot.
4. I also disabled driver signature enforcement: I downloaded EasyBCD and ticked "Allow use of unsigned drivers" under Advanced -> Advanced, then rebooted.
5. Finally I downloaded realtek_hda_6.0.1.8272_dts_ddl_experimental drivers above and installed them as normal. If asked to install unsigned drivers, choose "install anyway".
6. After installation, open the Windows "run" box by pressing Windows Key + R, type in "regedit" without quotes. Go to "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Audio". Add "DisableProtectedAudioDG" of DWORD (32bit value) type and set it to 1.
7. After rebooting, I was able to see the DTS Interactive (5.1) default format in Realtek control panel:
1619321679457.png


It might not make a difference, but I also plugged in 5.1 speakers via the regular 3.5mm analog speaker jacks on the motherboard, and I was using them for a while. I made sure to select the proper 5.1 speaker configuration. This shouldn't make a difference to the digital/optical out format, but it's something I did so I better mention it.

Thanks to @Alan Finotty for his help and I hope this guide helps someone in future.

Alan, if you have any idea why the driver from @dvojinov worked but the others didn't I would love to know.

I was looking for a quick solution and I was lucky enough to find this thread since I have the same motherboard. Thanks to your struggle, I got it working in no time. Just had to download the driver and do the registry edit. I can confirm it works on Windows 11 as well.

I have an MSI B550M Mortar motherboard and am currently running Windows 7. Everything works fine except I can't get the Realtek audio working to use with my S/PDIF optical cable.

Using Realtek's latest (2.82) drivers I was able to get the Realtek HD Audio Manager installed, but I still was not able to hear any audio come out of the speakers and I have not been able to see "5.1 channels" or see any Dolby Digital Live/DTS options anywhere.

I have tried several solutions including 2.81 drivers which apparently worked for another user with a B550 chipset (but they are running Windows 10 and I'm on 7).

When I try to install 2.80 or 2.81 drivers I see an error message at the end of the installation:

Code:
Realtek High Definition Audio Driver - InstallShield Wizard
---------------------------
Install Realtek HD Audio Driver Failure !!
[Error Code : -0001]

When I install the latest 2.82 drivers there is no error but there is no 5.1 or DTS/DDL options and I still don't have sound via optical cable.

In all cases, the driver displayed in Device Manager remains as "High Definition Audio Device" by Microsoft.

Any suggestions would be much appreciated. Thank you.
You do understand that optical audio is only stereo, yes?

The realtek ALC1200 does not include dolby digital encoding, so it can only pass through pre-encoded audio (DTS/DDL pass through from media players) - it cannot encode digital audio.

AFAIK all realtek chips can encode DDL/DTS, its just a Flag that gets set driver side

Correct, but without that driver mod (which is a f*cking nightmare to get working for many users) it's only going to work as stereo

nope. not ALL chips. ALC269, for example, is one that can't encode DDL/DTS

most ALC2xx chipsets like ALC269 (a laptop based 2-channel chip) can NEVER do DDL/DTS; the exception would be ALC272 in which that one has "optional" DDL/DTS support

this DDL/DTS stuff works best with either ALC6xx (like ALC662 or ALC665) or ALC8xx such as ALC888 & ALC892

All audio chips can encode DDL/DTS its a software based solution, none are hardware based AFAIK, It just a matter of driver support
