=== How to enable HDMI Audio support on fit-Headless GS ===
fit-Headless GS HDMI audio was qualified with NVIDIA and with Intel HD.<br>
We did not have an opportunity to test with AMD Radeon, and AMD drivers may behave differently.<br>
* In some cases system restart is required to enable the HDMI audio.
* Simplifying the setup - that is connecting a single fit-Headless GS to the primary (or better yet - single) graphics card.
Workaround reported by our customers - AMD seems to have a 165MHz pixel clock limit when using an HDMI connection, which is exceeded when using resolutions & refresh rates higher than 1080p@60hz.
Using a third-party utility ToastyX Custom Resolution Utility, import a custom EDID extension block for HDMI audio support, and remove all custom fit-headless GS resolutions from the EDID string that were higher than 1080p@60Hz. After reboot HDMI audio on the fit-headless GS should be present. Alternatively, one might be able to use the higher resolutions & refresh rates by patching the AMD Radeon driver to bypass the 165Mhz clock limit, although this can break HDCP functionality.
