<div>
<pre>In normal ALSA operation, you can enable timestamps on an audio stream using
the SND_PCM_TSTAMP_ENABLE flag to alsa_snd_pcm_sw_params_set_tstamp_mode().
Subsequently, calling alsa_snd_pcm_status_get_tstamp() (or the higher precision
get_htstamp) gives timing information.
On my machine this works fine with vanilla ALSA, but once I install an asoundrc
which specifies "type pulse" for pcm.!default and ctl.!default timing
information is no longer available (get_tstamp and get_htstamp always return
zero).</pre>
