[alsa-devel] dma buffer format

Takashi,

I am now working on a surround sound driver for the first time. I am confused by the packed format of dma buffer. If the channel number is 6, is the buffer filled with data as

front left, front right, rear left, rear right, center, LFE

or

front left, rear left, center, front right, rear left, LFE?

Thanks,

York
