From 3c7860c96f84145eb134436d1ef55b45fe21f40e Mon Sep 17 00:00:00 2001 From: jack Date: Wed, 8 Apr 2026 00:19:58 +0800 Subject: [PATCH] fix(wp): force HiFi profile for Kaisa UCM so HDMI routes appear WirePlumber often kept stereo-fallback when only enabling use-ucm, hiding HDMI. Set device.profile to HiFi, disable api.acp.auto-profile, and document recovery.
