At this moment, I just sample the tick value manually when I get an event. That kinda works, but chances are high that the kernel sequencer system can do that for me with more accuracy?
In your function that does the connection to the reception port... snd_seq_port_subscribe_set_queue(subs, queue_id); //<< queue_id being the one you allocated snd_seq_port_subscribe_set_time_update(subs, 1); snd_seq_subscribe_port(pSeq, subs);
This is the correct way to get timestamps on events that go through a subscription.
Alternatively, you can get timestamps on events that arrive at a port: snd_seq_port_info_set_timestamping(pinfo, 1); snd_seq_port_info_set_timestamp_queue(pinfo, queue); snd_seq_create_port(pSeq, pinfo);
