I only have schematics for Beagle ... which makes VERY minimal use of the twl4030 audio capabilities: - stereo "headset" output, without its mic - stereo aux-in Other twl4030 family boards *could* have: - microphone input for that headset - stereo "hands-off" speakers - mono earpiece output - two other microphone input channels And maybe more; that's just me summarizing unconnected pins, not the datasheet. There are also cost-reduced parts with less audio capability. I make no claim about audio expertise -- the nearest I come to it is observing a few years back that there was a huge framework hole, which ASoC seems to fill -- but I wonder if it shouldn't suffice just to provide a mask of capabilities that are wired up on a given board. - Dave _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
