It will work magically when re-loading the driver. [Fix] Backport the upstream fix c0f1886de7e1 ("Allow repeatedly probing on codec configuration errors) from 5.15.0 rc. It adds the capability for retrying the probe upon codec probe errors on the certain AMD platforms. [Test] 1. Connect the external monitor to particular affected AMD systems with HDMI or DisplayPort. 2. Go to Audio Settings to check if the HDMI/DP audio output device exist or not. [Where problems could occur] Should be low risk, it adds the chance for retrying codec probe and won't affect machines which used to work. ========== Original Bug Description ========== Can not detect DP audio output [Steps to reproduce] 1) install dell-bto-focal-fossa-grimer-rkl-X72-20210929-8.iso and boot into OS 2) switch to on-demand mode 3) connect an external monitor via DP Port 4) check sound setting --> Output Device 5) switch to performance mode 6) check sound setting --> Output Device [Expected result] System can detect DP audio output when external monitor connected [Actual result] Can not detect DP audio output This issue can be reproduce in on-demand and performance mode.
