It is possible to change the sound card setting at any time. Dependent on the specific model, there are some controls available, e.g. You can choose the used sound card from a drop-down list in the plugin’s menu before you install and use it after one restart of the Raspberry Pi.
Max2Play supports a whole series of sound cards for the Raspberry Pi. The plugin Raspberry Pi Settings offers more possibilities to configure, set up and maintain Raspberry Pi models.
