[PROBLEM] Latency reduction when using audio/video player as input

[jiemdev]

False alarm about alsa output in 16 bits. Changed my m3u playlist from alsa://plugpdifinput to alsa://plugpdifinput?format=48000:32:2 (didn't forced these before by thinking it would follow source format).

Still latency is exactly the same.

Have you tried the part of the tutorial from Bitlab that describes how to bypass MPD and use directly ALSA for capturing the input?
Maybe it's MPD the root cause of the delay... just speculating here, have no other ideas.

This is the next step in my todo list.
Then if I find a free sd card, will try Tim suggestion.
