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

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.
