I am looking for a method to maintain timestamps for every sample read or written.

ALSA does not have timestamps for every sample.

I noticed the *SND_PCM_TSTAMP_ENABLE mode. But the description mentions - "" *pdate timestamp at every hardware position update" Doe this mean that the when snd_pcm_htimestamp() is issued, we will get the last hardware update timestamp

Yes, this is what the documentation says.

or does it mean that it will fetch the timestamp of that particular sample?

Yes; it will fetch the timestamp of the particular sample that is returned in "avail".
