Dan Kovacek 32c364e350 sof-soundwire: rt711-sdca: set PGA30.0 volume in BootSequence
No sound from headphone jack on Dell Precision 5480, Ubuntu 24.04.4 LTS kernel version 6.17.0-20-generic

The SOF DSP pipeline volume PGA30.0 (pipeline 30, PCM device 0) defaults
to 0 at boot, which the dBscale treats as a hardware mute. The DAPM chain
is active and audio flows on the SoundWire bus, but the pipeline passes
silence into the codec.

Set PGA30.0 30 Playback Volume to 32,32 (0 dB) so the pipeline is not
muted when headphones are enabled. Software volume is applied on top by
PipeWire/PulseAudio independently.

Tested on Dell Precision 5480 (Intel Raptor Lake-P, rt711-sdca on
SoundWire master-0-2).

alsa-ucm-conf

ALSA Use Case Manager configuration

Installation

Copy the ucm and ucm2 trees to the alsa-lib configuration directory (usually located in /usr/share/alsa) including symlinks. The files in the package root directory (README.md, LICENSE and VERSION) files are extra (only informational).

Example:

tar xvjf alsa-ucm-conf-1.2.6.2.tar.bz2 -C /usr/share/alsa --strip-components=1 --wildcards "*/ucm" "*/ucm2"

The latest configuration can be obtained with those commands:

curl -L -o alsa-ucm-conf.tar.gz https://github.com/alsa-project/alsa-ucm-conf/archive/refs/heads/master.tar.gz
tar xvzf alsa-ucm-conf.tar.gz -C /usr/share/alsa --strip-components=1 --wildcards "*/ucm" "*/ucm2"

State file

Some values may be set only one time by UCM and then they are saved to the global ALSA sound state file. Please, make sure that this state is cleared, if you have an issue.

Commands for standard systemd setup (relogin is required):

systemctl stop alsa-state
rm /var/lib/alsa/asound.state
systemctl start alsa-state

Validation

Validate UCM configuration

The UCM configurations are automatically validated using the UCM validator available at https://github.com/alsa-project/alsa-tests/tree/master/python/ucm-validator .

If you create a pull request for new hardware, please, add also the alsa-info.sh output to emulate this hardware in the UCM validator.
