- I really dislike the fact that ALSA insists to do the channel reordering for me if I access the audio device via "surround51:". In the interest of having the shortest pipeline possible with no redundant steps in PA, I'd prefer if I could open the device as hw:0, and query the suggested channel ordering of the HW, instead of always having ALSA around doing the rearranging.
Yes, querying channel mapping is another missing piece with popular demand.
The implementation would be easy, I guess. But we have to define the way to inform this from kernel to user space: whether create a new ioctl or extend the existing ones (if possible)...
