Help needed: can't get Realtek ALC1200 working on MSI B550M motherboard under Windows 7

[Mussels]

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

thanks for the specifics - i wasnt sure.

I know that some common ones had the DDL hardware, but disabled via the software since the mobo makers didnt pay the licence fee, but as time goes on they're less and less common

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:

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:

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.

MAAAAAAATE!!! I COULD KISS YOU RIGHT NOW! IT WORKS! I HAVE TRY DOZENS OF SO CALLED BEST AND 100% SURE WAYS TO DEAL WITH IT.
YOU HAVE JUST SAVED ME FROM THE 3RD DAY OF GOING MAD BECAUSE OF THAT! I SALUT YOU!

im also going to be trying this exact method on:
windows 11
ALC1200
will report back in a min.

how do we stop windows from automatically updating to the new "Dolby" updates in windows 11 updates area?
"Pause Updates"?
that only last for so long.

Disconnect wifi/ethernet or enable a gpedit.msc command or regedit entry.

 

[tdbone1]

so i was fully updated on my windows 11 rig as of today 07-12-2022 11:58pm gmt-6
ALC1200
qsg-sb3821c6 and that the vizio 5.1
i pretty much just did the disabling the driver signature in the windows 11 advanced startup features then i did the regedit but skipped the manual removal with that program that was mentioned. i did download the program though.
i didnt remove the drivers as mentioned above through device manager.
basically at this point i just ran the driver installer but of course it wants uninstall then restart then install and restart.
so i completed the installer without doing the F7 disable driver signature thing for the actual install part of the installer (part 2)
anyhow i did wind up perm disabling driver signature and also secure boot.
i have 5.1 but im missing alot of codecs
in the sound manager (realtek and windows) i cant pick alot of options but when i game i have DDL 5.1 and thats all i care about!
whoot
thanks

This one is the key - it converts analog/PCM 5.1 into the digital standards that SPDIF uses

These are pass-through settings, for example passing through audio from a DVD or BD without the PC touching it in any way (which often mutes all other audio, so if you get one audio source working while others go silent, untick those boxes to fix it)

The rest is less important, but those two are the keys to watch - people always think the passthrough settings are encoding and get confused by it
