Sound card issue with ryzen9 3900x，gigabyte x570 arous pro wifi #22

CPU:AMD Ryzen9 3900X macOS version:10.15.3 19D76 15h/16h or 17h:17h motherboard: gigabyte x570 arous pro wifi **sound card:Realtek ALC1220VB I'm sorry to bother you Developers.

I kept using this patch during macos catalina 10.15.1-10.15.3.I've found that when I watching videos with trueHD/7.1ch/5.1ch audio (Playing on dual channel audio player

sound_Windows_7.1ch.m4a.zip sound_macos_7.1ch.m4a.zip

)it has crackling noise frequently and can't fix.Sometimes it even stop for a while with the video together.At first I think it is the Whatevergreen plugin going wrong so I've tried to deleted it(I can boot up without it)but it didn't work.Then I tried the latest version of Whatevergreen,the problem still exists,and when I switch the output to the HDMI,it runs well.So I've tried to build AppleALC with my codec and inject all the layout-id listed in applealc and it's useless.I even tried VoodooHDA.kext and only if you switch the audio output to the HDMI cable(my video card is RX5700)or you'll hear the random noise. (BTW Dual channel audio is just fine.but sometimes when I watch videos online it will happen too.That is odd(I don't think online videos also have 5ch/7ch/truehd audio data in it)) So I want to ask for help, whether you can find reason and fix it, and whether I need to do something to coordinate you Developers ?

Here are some examples for you.I recorded sound from frozen ii bluray-disc for example(when playing on macos it has many noise in it,while windows10 is fine)

Looking forward to your reply, and thanks very very much!

Latest information：it's getting worse and it happens randomly.I can not find what exactly causes this issue. Premiere 2020 works well even with 7.1ch audio.Kinda like software issue.But nearly every kind of video player have this issue,it is very hard to judge.

No one helps ........ I‘ll continue to test on my own and hope to fix this issue Latest information:I tried to disable precision boost.I even set a certain processor clock to test.Problem still exists,But when I tried to clock down the FCLK to 1600mhz it feels better. 1800mhz FCLK works fine on Windows(truehd5.1,7.1)noise on macos(truehd5.1,7.1) 1600FCLK less noise on macos AC3 5.1,7.1 is fine on both windows and macos I don't know what codec the online video website(such as youtube)use so.....
