The codec driver is a dummy driver for bt device and actually do nothing. The user-space will control both bt part and alsa part (at least in mt2701 platform). Yes the sound/soc/codecs/bt-sco.c was only support 8k and was already there before the patch, but I think it might be ok to extend it to 16k without any side effect. If you worry about some potential risk (I don't see any) maybe we have to develop another dummy bt-sco codec driver which support both 8k and 16k? _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
