Hi Kuninori, I have no plan. My Cubox machine has too many specific code and it is used in an organ as the sound synthesizer. I will not do any more development in its kernel. In my new machine, an Orange PI 2, while audio on HDMI is working for me, there is still a lot of job to do aside (YUV video, analog audio, embedded wifi...) and I am blocked by the HDMI driver which has no free license nor documentation about the hardware. So, I have not submitted yet a patch series about audio for this machine. Otherwise, if you read the previous discussions, I think the most important is Mark's remark (Sat, 7 Feb 2015 16:33:55 +0800 in the alsa-devel mailing-list): > We already have simple-card to provide a binding for trivial > systems and don't want to end up with a never ending series of slightly > more complicated bindings which each cover slightly different sets of > systems in ways that users struggle to differentiate between. -- Ken ar c'hentañ | ** Breizh ha Linux atav! ** Jef | http://moinejf.free.fr/
