Devicetree changes for DP/HDMI submitted here: https://lore.kernel.org/lkml/20260831-surface-pro-11-dp-audio-v1-1-fb9c0d3216b7@gmail.com/ Tested on a Surface Pro 11 with a HDMI display attached via USB-C adaptor. Switching between speaker and HDMI profiles works fine with PipeWire. However, the DisplayPort audio IP is powered off while no display is attached, so PipeWire's probe of that PCM fails and the profile is dropped. Displays must therefore be connected before PipeWire starts: https://lore.kernel.org/all/76b8ca1d-040b-472e-9804-5c0c0100b5b5@oss.qualcomm.com/ Request URL : https://github.com/alsa-project/alsa-ucm-conf/pull/847 Patch URL : https://github.com/alsa-project/alsa-ucm-conf/pull/847.patch Repository URL: https://github.com/alsa-project/alsa-ucm-conf ^ permalink raw reply [flat|nested] only message in thread
