Subject: Multiple channels mapping
Date: Tue, 07 Feb 2012 17:02:00 -0800	[thread overview]
Message-ID: <4F31C988.3090201@codeaurora.org> (raw)

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
