* ucm2: Qualcomm: x1e80100: Surface11-HiFi: disable DP RX mixer routes by default [not found] <alsa-project/alsa-ucm-conf/pr/889@alsa-project.org> @ 2026-10-23 17:30 ` GitHub pull_request - opened 0 siblings, 0 replies; only message in thread From: GitHub pull_request - opened @ 2026-10-23 17:30 UTC (permalink / raw) To: alsa-devel alsa-project/alsa-ucm-conf pull request #889 was opened from ramonjesusmiranda-debug: SectionVerb in `Surface11-HiFi.conf` unconditionally enables the `DISPLAY_PORT_RX_0` and `DISPLAY_PORT_RX_1` Audio Mixer routes (`MultiMedia3` and `MultiMedia4`), and `SectionDevice."HDMI0"` / `"HDMI1"` lack a `DisableSequence`. When PipeWire / WirePlumber starts or probes the card with no external DisplayPort monitor attached, opening `MultiMedia3` / `MultiMedia4` triggers 44 to 54 errors in `dmesg` on every start/restart: ``` hdmi-audio-codec hdmi-audio-codec.2.auto: ASoC: error at snd_soc_dai_startup on i2s-hifi: -22 ``` Keep the DisplayPort mixer routes disabled (`0`) in `SectionVerb` and add the matching `DisableSequence` to `HDMI0` and `HDMI1` so they are only enabled when an external DisplayPort audio sink is actually selected. Tested on a Microsoft Surface Pro 11 OLED (X1E80100).
