Jaroslav Kysela cd342774cd sof-soundwire: cleanups for codecs with multiple functions The load mechanism assumed only one multi-codec in the system, but we saw in #774 multiple instances of those codecs (rt1320 and rt713). Make the load mechanism straight: - introduce file variables - remove shadow variables - probe multi-codecs separately and modify the file variables - test for duplicate file inclusion (in both sof-soundwire / HiFi configs) - merge dmic configs for rt712,rt713 to one file This change also improves filters for speaker/headset/mic init includes.

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

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.
