I can confirm that sound works for me as before, both capture and
playback, on my OMAP1 Amstrad Delta with Russell's and Peter's patches
applied on top of linux-3.6-rc3, with the OMAP DMA engine driver built
in. I was not able make audible tests with applications other than a
soft phone as I didn't get back home for this weekend, but I think that
the asterisk soft phone is quite a demanding use case.
The only thing I'm not sure about is why the sysfs provided
bytes_transferred values never change from their initial zeros.
