About Panda UCM, last week I noticed though that there is different wiring on input side between 4430 Panda (line in goes to analogue headset mic inputs on twl6040) and 4460 Panda (line in goes to FM analogue inputs). So this week I plan to make changes to the onboard audio driver to change its alsa card name based on what board it's on, with a view to elaborating out the UCM directories so the recording case is handled correctly depending on the board.
That's my concern too. The first thing is we need directories under /usr/share/alsa/ucm with the same audio card names on both panda boards. The second thing is to have correct configurations for both boards. I don't have a 4460 board, Andy, can you help on giving the ucm configurations for it?
