|
|
## 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.
