[PD] Pd-extended 0.42.5 Lucid - Audio Settings / Delay - notworking!

[Ingo]

No Bernardo,

I get the same or even better latencies. Down to 5-6 ms (pd audio sttings
display) with a very complex patch. Alsa is giving me more problems like
digital A/D/A sync errors.
As far as I know alsa is using oss anyway. Not sure if I'm wrong here.

Anyway, I just figured out what the problem was. I had a "-blocksize 64"
flag set when starting the patch. Changing this blocksize to a higher value
like 512 did the trick. Now higher delay settings have an effect.

Seems a bit strange to me as the actual blocksize doesn't seem to change but
the maximum buffer size is increasing.

It also like it's giving me a slightly lower cpu consumption (10-20%). I'll
have to try different values in order to see what seems to be the best
setting.
