Message-ID: <47413D60.9000404@cs.helsinki.fi> (raw)
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.
