Symptoms: If you have AMD CPU or GPU, on rare occasions, Discord could stuck in RTC CONNECTING when trying to connect to a voice channel. We believe this issue mostly impacts older models. Discord in the browser has no issue connecting to voice channels.
Reason: Discord may get stuck in initializing/querying the AMD hardware video encoder.
Please make sure that Discord is installed properly. You may try to uninstall/re-install Discord.
Please make sure that your GPU driver is up to date.
Disable "OpenH264 Video Codec provided by Cisco Systems, Inc." in Voice and Video Settings.
How do I check my GPU driver version?
Run command DxDiag. Under Display tab, it should show your GPU information along driver version.
