Hello,

I have now tried in various ways to get my Polk Audio MagniFi Mini AX to run on the PC via Hdmi.

-Reinstalled all drivers
-Replaced Hdmi cable
-Tested on the PC via AMD and Nvidia connections and even on a laptop
-Other sound devices work via Hdmi
-All drivers are recognized by Windows, but MagniFi Mini AX does not seem to communicate with the PC via Hdmi
-I can see that several people have had problems with this.

I therefore assume that this is a firmware problem. Could you please test AMD and Nvidia on the PC via Hdmi with the Polk Audio MagniFi Mini AX?

    His response:


    "Did OP post any specs on his PC? Not all GPUs offer ARC or eARC which might be the issue happening here. Most PC's do not have that functionality unless a part was installed intentionally with that feature. It could be connected via Optical which would work fine but if they are attempting to connect it via HDMI on a PC, about 90% of HDMI ports on PCs are just the video outputs and not able to do an audio connection."

    My specifications:

    Nvidia RTX 4080 Super
    MSI MAG B650M Mortar WiFi with AMD Ryzen 9900X3D

    Both devices support audio via HDMI and the corresponding drivers are installed, but the Polk Audio MagniFi Mini AX soundbar is not recognised on both HDMI ports (graphics card and mainboard) when plugged in.

    Optical is unfortunately not an option, as only 2.0 sound is possible, but I want to control 2.1 to calibrate the subwoofer and this is only possible via HDMI.
