W/O changing anything after installation, DTS live & DTSi options appears for my DIGITAL output - BUT WAS STEREO ONLY ( not 5.1 !)Īpparently SB720 is the culprit - not only it refuses to work for the DIGITAL output and do only work when SPEAKER(analog) is enabled.

So to disable it - one should enable speaker output, goto realtek panel, DISABLE "SounzReal VoizReal EXP", then disable speakers.

Install the R281 driver – "Setup.exe" file in main driver folder "0008-64bit_Win7_Win8_Win81_Win10_R281". Allow Windows to run the patch – ignore any warnings.ĩ. Run the Patch file two times once to patch the file name "RltkAPO.dll" and again to patch the file "RltkAPO64.dll". Copy unzipped Patch file & paste it in the unzipped R281 folder “WIN64”.Ĩ. If Windows Defender causes issues, then open Windows Defender & allow the file to be created.ħ. Restart PC (use DDU recommended option to restart).ĥ. Make sure to select audio drivers in the App.Ĥ. Use Display Driver Uninstaller (DDU) to wipe old Realtek audio drivers. Restart PC in Safe Mode with no network connectivity.ģ. (Google alternate source if that doesn’t work).Ģ. Not sure how this will work with other boards/codecs, so use at own risk - create restore point just in case. Thought I’d post a step by step on how I got the optical out of my Gigabyte B550 Aorus Pro AX motherboard (Realtek ALC1220-VB codec) working & sending a multi channel signal to amplifiers capable of decoding a compressed DTS Interactive/Dolby Digital Live in either 5.1 or 2 channel stereo.
