S3221QS, audio usage
Hello, I just purchased two of these monitors to replace Apple Cinema Displays on a MacPro system. The GPU is an AMD Radeon HD 7970. Each monitor is connected with a 4K cable with mini DP on the GPU end, and DP on the monitor end. I have also connected the USB cable Dell provided from a USB port on the computer to the "upstream" USB port on the monitor.
My question is WHERE does the audio come from on this monitor? Does it or can it come on the USB cable? The DP cable? Or, do I need a third separate audio cable from the "audio out" on the MacPro to the "audio in" on the monitor?

Here is the online S3221QS User's Guide.
Here is the S3221QS driver page.
The S3221QS has two built-in 5W speakers. Turn them on in the Menu- Audio -Speaker. Or you may use the Audio Line out port for powered external speakers.
The Windows OS PC provides the audio source into the S3221QS via the HDMI or DP in ports. We cannot speak to the non-supported Mac OS.
