MP 1,1-5,1 Mac Pro 5,1 Sequoia Audio Issues

Mac Pro Early 2009 5,1 2 x 2.26GHz Quad-Core Intel Xeon with 32GB 1066 DDR3 and AMD Radeon RX560 4GB
OCLP 1.5.0
Running: OS Sequoia 15.2

Sequoia has been running without any issues since I installed it with OCLP except for my audio.
I get sound from internal speakers but not through my line-out or HDMI on my Asus MX299Q. I had the same issue with Maverick but was able to solve using Soundcontrol but nothing is working this time on.
Any help with resolving this issue would be appreciated.

The processors are not compatible: https://forums.macrumors.com/threads/strange-audio-issue-on-mp-4-1-5-1-mojave-10-14-4.2176792/

Edit: this is for stuttering sound, but as soon you find out, that you need to set sound output accordingly, you will hear the sound is not stable.

Thank you for the response, I appreciate it. So if I want to continue using the latest OS with OCLP, i'm going to have to live with just getting audio through my internal speakers then.

no, You should adjust that with the pref pane. This is german, but you will find it by comparing the lines:

set it to line out.


The issue is that those old Xeon processors of MP41 are not fully compatible with newer MacOs versions. They tend to produce stuttering sound, even with external sound processors.

I tried that and I get no sound from line out or HDMI through my monitor

hook a headphone to line out, set volume to 100% and double test

Interesting, so I plugged in the line out to my jambox and it works 👍👍. Yet when I plug the line out to my monitor (Asus MX299) it doesn't work nor does audio through the HDMI that is connected to the monitor. I guess I need to troubleshoot my monitor even though it worked with previous OS with soundcontrol.
Thank you again.

HDMI sound is another topic, what needs more fiddling. For analog sound your display should have a setting in its menu to activate.
