hi all,

I got few amps and speakers, and set up aggregate 8-ch usb audio on osx 10.8.2 First, not related to csound, sound flower and and audio settings work when they like. I set very simple csd: it reads 2-ch from soundflower and then output 8-ch audio to either soundflower  or aggregate device. Sometimes it works, sometimes not. Problem seems to be soundflower or aggr. dev in general, configuring speakers to need  luck. Then after trying too many times, and csound really many times, csound started to slow down. The audio from outo was few hundred ms ok, then a big pause, then again ok, then pause etc. This happened repeatedly, although I stopped every instance of audio programs and csound. I used just iTunes to put audio to soundflower and once and a while could get audio from all speakers. This maybe a osx bug, before 10.8.2 using iTunes in the same time as audio setup, crashed iTunes or audio setup program, haven't noticed the crashes with 10.8.2, but something wrong there is. Anybody else have noticed some weirdness with osx audio?

Another question: selecting just -o dac and -i adc, do csound select whatever is set in the audio setup, without specifying dacX? Old Cecilia uses -o devaudio and and I need to put audio and get audio from specific sound card.

tnx
