That's not what I wrote, and that just means it's obvious enough that there's 
no point reopening the topic.

I don't see how the patchset is useful. I've seen requests for PCM pass-
through, which sort-of makes sense with a digital output, but that's not at 
all what this patchset does.

PCM pass-through means that you set exclusive mode and force the DAC format to 
match the sample rate, channel map of the decoded input, and pick the wire 
sample format, practically signed 16-bits. This patch does almost the exact 
opposite: negotiate the rate, map and bit depth.
