|
|
+The UCM configurations are automatically valited 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.

+The driver name can be obtained using procfs like:

+````
|
|
+ cat /proc/asound/cards
