Sometimes back I also was thinking of having single user config for a group of machine configs. I dont know if people really care about various types of skylake audio machines so enabling all of them with a single option maynot be a very bad idea... thoughts? This way we can have a skylake based, legacy BYT, HSW group, Atom BYT-CHT group. Distro anyway enable all and having all drivers selected works fine This way our expanding kconfig can be limited. > And I believe there are a few more possible cleanups / fixes in the > messy Intel ASoC Kconfigs.

Looks like it was missed indeed, I will send this one out too and lets discuss which way all like to solve this and I shall send patches :) -- ~Vinod _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
