Hi victor, that is what Im doing. this is how i built csound on ubuntu:
scons usePortAudio=0 usePortMidi=0 useALSA=1 useJack=0 useFLTK=0
buildLoris=0
now, when i start grace I configure the csound port like this:
Settings: -+rtaudio=ALSA -o dac:hw:0 -d
CSD File: /home/hkt/grace.csd
but when i open csound i get this error:
[...]

Csound uses portaudio as default, so if it's not there it complains
(I'll
try and chnage this). But there is a quick solution, just pass on the
options
-+rtaudio=alsa to use the native alsa module or
-+rtaudio=jack to use jack if you have it.
-+rtaudio=coreaudio to use the native coreaudio module
-+rtaudio=mme to use the native MME module
These as you know can go in the CSD <csOptions> section, or
as compilation options.
