Dear all, I am having a question regarding how to specify 'champ' for a plugin. I do not see any examples of this. I tried many ways to specify but failed. As indicated by the link below, I can specify the MAP as a string array. Can someone provide one example on how exactly this [chmap MAP] can be specified? " pcm.name { type cras [chmap MAP] # Provide channel maps; MAP is a string array } " https://www.alsa-project.org/alsa-doc/alsa-lib/pcm_plugins.html I can something like these, but none of these work for me. chmap LFE chmap "LFE" chmap FR,FL,LFE champ "FR,FL,LFE" Thanks!
