If there is no get_time_info() available or the requested audio timestamp type is AUDIO_TSTAMP_TYPE_DEFAULT then need to set audio_tstamp_report.actual_type = AUDIO_TSTAMP_TYPE_DEFAULT (in the else clause near the start of snd_pcm_update_hw_ptr0()) in order for update_audio_tstamp() to generate the audio timestamp from the number of frames.
