I am trying to get audio through HDMI to a Samsung TV.
PC parts: AMD Ryzen 5 2nd Gen 3400X MSI Radeon RX580 8Gb MSI Carbon x370 Gaming Pro (BIOS up to date) 16Gb RAM Windows 10 x64 - 1909 (up to date) Adrenalin 2019 Edition 19.9.2(WHQL) also try with Adrenalin 2019 Edition 19.11.3
Here are the details and issue:
Without GPU: If I use integrated graphics rx vega 11, the sound works fine hdmi to TV. With GPU: If I connect hdmi to tv, video works fine but no audio, I have try both hdmi ports on rx580. I have tried with both drivers, using DDU to switch between drivers. With GPU: If I go to the sound icon, I can only see Digital Audio(S/PDF), I cannot see the TV listed as an option for audio output. Without GPU: If I use the integrated graphics, If I go to the sound icon, I can see the TV as default and the Digital Audio(S/PDF). I have another rx580, and the same issue with both cards. With GPU: If I plug an USB headset, audio works fine through USB. With GPU: if I go to device manager, under Sound..., there is only 1 device listed. When I go to Radeon settings, System, Software: AMD Audio Driver Version: 10.0.1.12
Initially Y built the PC with all the parts listed, when I notice that there was no audio, I uninstall the GPU and use integrated and the sound worked without GPU. I then went to safe mode, use DDU, uninstall drivers and shut down, I reinstall the GPU but same issue, no audio.
