[alsa-devel] alsa timestamps

Hello list,

I took up some old dusty code of mine that uses snd_pcm_state followed 
by snd_pcm_status_get_tstamp when in capture mode. The code used to 
work, but now the returned timestamps are all zeroes. Is there some API 
change done recently or is the whole timestamping deprecated or 
something? I've tried with different drivers on ubuntu's alsa .14 and 
gentoo's .14. I've also tried mmap'ed and r/w modes, and I'm setting the 
TSTAMP_MMAP sw param.
