Hi,
The DSP I am working on supports channel assignments similar to ALSA route plug-in described in this link http://drona.csa.iisc.ernet.in /~uday/alsamch.shtml. I am currently looking a way to pass channel/speaker mapping information of PCM stream( i.c channel 0 -> Front Left speaker, channel 1 -> Front Right speaker) to ALSA driver. I looked at latest kernel tree and don't think there is already provision for my purpose. Can anyone confirm? If I were to improvise a way to pass channel/speaker mapping information, should I follow the same approach similar to how bits per sample and other hardware parameter is passed?
Thanks Patrick
