[LAU] (Ardour) How to get rid of delay when recording ?

[jonetsu at teksavvy.com]

Hello,

When recording acoustic guitar wearing headphones, the delay between
the note being played and the headphone output is so noticeable that
for fingerpicking with only but a soft synth pad as background, it is
difficult to play a good track.  It is way too distracting.  The
workaround is to put a click, a high hat for instance and be oblivious
of anything else and try for the best.  But it is certainly not free
playing as if playing along when the same is coming out the speakers.

In Ardour 4.6.0 changing the monitoring from Ardour to hardware does not
improve anything.  Any advice, hints, suggestions will be much
appreciated.  Here is the setup.  1010LT card with playback outputs 3
and 4 send to a Behringer HA400 headphone amp.  Just about no plugins
in Ardour,  No xruns seen in quite some time (eg. i5 3.40GHz CPU is very
likely running under no stress) 16G RAM.

It would be so nice to have no delay at all!

Cheers.
