After testing out this problem over the last few days it seems that my awe32
card is the real reason for latecy problems. For some reason when trying to
duplex record, ecasound's engine takes a few seconds to start. I've tried
with numerous setting changes eg nointbuf/intbuf, lowlatecy/non lowlatency
enabled in kernel, doublebuffering/nodb etc. I'm not sure this card is truly
capable of full duplex... anyway. I then tried the same with a trident card
and was able to get low latency recordings - shame that the sound quality
form the these cards is so crap, even if you record at 48k, with levels
perfect it sounds fuzzy! Looks as if I need to by a new card. Any suggestons
are welcome??
