The trigger/current timestamps are not related to the buffer/queue. They are useful only to relate the audio stream position to the system time. >What exactly is meant by "current system timestamp"? Is it provied by ALSA >(htstamp?) or should I use clock_gettime(CLOCK_MONOTONIC, >&system_time); to get that timestamp? They are the same. ALSA returns it to prevent your process from being interrupted between measuring the two clocks.
