NAME
       struct_snd_compr_tstamp - timestamp descriptor

SYNOPSIS
       struct snd_compr_tstamp {
         __u32 byte_offset;
         __u32 copied_total;
         __u32 pcm_frames;
         __u32 pcm_io_frames;
         __u32 sampling_rate;
       };

MEMBERS
       byte_offset
           Byte offset in ring buffer to DSP

       copied_total
           Total number of bytes copied from/to ring buffer to/by DSP

       pcm_frames
           Frames decoded or encoded by DSP. This field will evolve by large steps and should
           only be used to monitor encoding/decoding progress. It shall not be used for timing
           estimates.

       pcm_io_frames
           Frames rendered or received by DSP into a mixer or an audio output/input. This field
           should be used for A/V sync or time estimates.

       sampling_rate
           sampling rate of audio
