Hi
I am looking into commit 3179f62001880e588e229db3006a59ad87b7792a ("ALSA: core: add .get_time_info"), which, if I understand the code correctly, changed the behaviour of timestamps. Before this change, snd_pcm_update_hw_ptr0() just returned if the no_delta_check showed that the hw_ptr had not changed. With this change it will update the timestamps before returning.
Was this intended, and if so does anyone have any insights to why? The original behaviour to not update the timestamps when the hw position has not changed seems more correct to me, but I am new to this code.
