It looks like this might be more relevant on alsa-devel. Some more details on the platform might be useful.

Hi PulseAudio forks,

snd_pcm_htimestamp is unstable after change the date time of OS by using "date -s xxx-xxx-xx", It is very strange that the time value get from snd_pcm_htimestamp is always 1420588802151082308

and here is what I get when cat the alsa infomation:

uid=0 gid=0@nutshell:/ # cat /proc/asound/card0/pcm0p/sub0/status
state: RUNNING
owner_pid   : 1339
trigger_time: 1420591411.800808521
tstamp      : 1420591457.486751372
delay       : 5040
avail       : 3152
avail_max   : 0
-----
hw_ptr      : 2193408
appl_ptr    : 2198448

Does anyone met this problem before ?

Thanks!
