On my desktop PC, on snd-hda-intel with analog outputs for S16LE

stereo, the granularity is 32 bytes (= 8 samples), and I get the pointer granularity of 64 bytes (=16 samples) over HDMI. The minimum period size is 32 samples in both cases.

Do you mean hda-Intel does not support arbritray period size when you say the granularity is 32 bytes ?

However the granularity of the emulated hda sound card inside any VM depend on the vm and the backend audio system and sound card

The precise meaning is defined here:

Of course the VM result would be different.
