This was the original bug that caused me to start looking at the ring buffer functions.
In the API this is documented as:
"Delay is distance between current application frame position and sound frame position. It's positive and less than buffer size in normal situation, negative on playback underrun and greater than buffer size on capture overrun. "
Because dsnoop was returning the buffer space available to the hardware the return value was always quite large, and moved in the wrong direction.
With this patch, dsnoop now gives results which are comparable to using the "hw" device directly. My test case was with snd-echo3g (Layla3G).
