ASUS PRIME z490-P 10900K Audio

Hola and Greetings Ladies and Gents,

Specs for those who did not see my initial post...

CPU: i9 10900k - dellidded, and binned as stable at 5.4 all core under direct die cooling - I bought a Rockit Cool copper IHS kit and slapped that on.  Currently OC'd via ASUS mobo at 5.2 all cores.

MoBo: Asus Prime z490-P open box

GPU: Sapphire Nitro+ RX 5700xt from a college kid who stood in line at MicroCenter in NJ and snagged a RTX $3080 and was kind enough to sell me this one at a non-scalper price.

AIO: NZXT x53 (new)

Case: TT Level 20 MT - I liked the looks of it and got it open box

Ram: Patriot Viper 32GB (16gbx2) 3600mhz NewEgg flash sale

PSU: TT 850w - I swear I bought it 2 years ago for $50 and it has been sitting in my office drawer

NVME: 2tb WD SN750 bought on Mercari

Wifi/BT: Fenvi T919 on Ebay

Used cables and fans in amazingly good condition.

Currently everything is working beautifully, dual boot to either MacOS 11.2.3 or Win10Pro 20H2 on separate WD_SN750 2TB drives in M.2_1 and M.2_2.

But my audio out via any front or rear ports are 'borked' according to OC Configurator.  The only audio that works is via HDMI to the temporary TV I have the system hooked up to as I await a 38" widescreen.

Any guidance/help you could provide will be richly rewarded. (that includes a $50 sent to your PayPal account or some PC parts that I have that might be useful to you)

I really just want to send audio via the mobo S/PDIF output to my Denon reciever to have a 2.1 channel experience with this rig.

first delete  layout-id from properties

open nvram section in configurator and boot-arg  add this  alcid= 

and try these values 3 o r  11 or  13 and so on  15, 17, 18, 20, 21, 27, 28, 29, 30, 31, 66, 71, 86, 99, 100

each number individual not all

needed the list to run the audio.

  • AppleALC.kext
  • FakeID.kext
  • FakePCIID_Intel_HDMI_Audio.kext
  • device-id=709D0000
  • layout-id=15000000

your config just

                <string>-v keepsyms=1 debug=0x100 alcid=1 agdpmod=pikera</string>

need reconfig

Ok.  Audio is working, now I have to find the right layout ID (alcid=* * in boot-args of config.plist)for this ASUS PRIME Z490-P (Realtek ALC887)


I'll report back when I find it, and will post a link to my working EFI.

On my Gigabyte H97-HD# using the same ALC887, ID-1 or ID7 works with all internal ports (headphone etc) and if using a USB DAC sound device. If you have an SPDIF (I only use optical) riser card or ? motherboard based port - try to use id-99.
