B550M Steel Legend Realtek Audio issue

Hello

I replaced my B350 PRO4 with a B550M Steel legend few week ago.

Happy with the product that allowed me t push my RAM OC further, and to have the upgraded Audio feature provided by this board was a must.

However I am facing a headache issue. I am using a 5.1 surround system through the jacks connection on the board but I acnt output sound from the Rear, center and subwoofer. Only the front stereo speakers play sound.

I am using the Audio drivers+Nahimic package form asrock website so setting things through the Audio console in the latest Windows 10 build.I Can not find an Option for "speaker Fill" that used to be on the old Realtek audio Manager.

But doing the Test tone in Windows sound panel, I can hear sound being played from each speaker.

Any idea how I could fix this problem?

Thanks so much

thanks for your reply.The Problem is how to figure out which driver includes the "Speaker Fill" feature because I have no clue.

What I found out yesterday is that with Games that support 5.1, if I switch Nahimic ON then my surround system output sound from all speakers so thats good.

But with Youtube or Music content, no joy.Sound output remains only from the Stereo front speakers.

I have done some more brainstorming and testing, and found out that using an audio mixer software like Voicemeeter allows me to output sound from all speakers in any situation but its not the most practical Option

I hear you.The frustration for me is that its the 1st time I am having such Audio issue on any PCs I have built over the years.
I moved from an Asrock B350 with very basic audio feature set and codec where I didnt have any problem to output 5.1 sound, to a more premium B550 board with improved codec and upgraded jack connections.
So for me without any doubt I was hoping to experience even better sound and features.

Would you say the issue is with Microsoft, realtek or Asrock themselves?

Carried over from previous install actually.

Yes I am with you and I had considered that Fresh Install Option but decided otherwise since I am running a Fuze drive solution from Enmotus (equivalent to AMD StoreMi)and they were recomemdning to just deactivate and reactivate the licence in case of the Fats drive not being the one where the OS is installed

I did update the Chipset drivers since I was moving from B350 to B550 anyway, and also DDU my Radeon drivers and installed the latest ones after that.

All the other HW devices had no issues, just the Audio one

I will try to remove Realtek/Nahimic entirely and just run through Windows HDA to see if that works but this kind of kills some of the benefit of the Audio feature coming with the MB

thanks for your advice
