I can find mentions of the CMI8888/CM8888 in the Linux kernel sources. I also found this post from 2014: https://sourceforge.net/p/alsa/mailman/alsa-user/thread/536B28B2.1010107%40googlemail.com/ Although it only mentions the CM8888 specifically in the patches which are linked to. In a 2019 post here: https://www.powerpc-notebook.org/2019/08/c-media-supports-our-open-source-powerpc-design/ the group says: "They [C-Media] know that their chips will be in our Open Source Hardware motherboard and will provide us with the needed information to write drivers as may be needed." Is the CMI8828/CM8828 supported in Linux? Thanks! PS: Some sellers call them CMI**** and some call them by CM**** my research has shown that they're identical chips. _______________________________________________ Alsa-user mailing list Alsa-user@xxxxxxxxxxxxxxxxxxxxx https://lists.sourceforge.net/lists/listinfo/alsa-user
