Did I get these correctly? Is the rootfile system the same between these cases? I.e. that same mixer settings like audio volumes etc. are used? > Can anyone refer me towards the ones who worked on this kind of audio codec > driver. > Worth to ask also on linux-omap mailing list (linux-omap@xxxxxxxxxxxxxxx) since TI engineers are reading it.
