excuse me ... forgot to fill out the subject ..
did a dist-upgrade for UbuntuHardyAlpha3 last weekend
and the RT kernel became a bit older than the generic one
was using the system as CUI but since the setup for awesome went okay
also installed emacs-snapshot-nox and supercollider
even though ChucK works fine with jackd
when i do
emacs -sclang
and try to boot the server
it returns
JackDriver couldn't connect alsa_pcm:capture_1 to SuperCollider:in_1
JackDriver couldn't connect alsa_pcm:capture_2 to SuperCollider:in_2
JackDriver couldn't connect SuperCollider:out_1 to alsa_pcm:playback_1
JackDriver couldn't connect SuperCollider:out_2 to alsa_pcm:playback_2
i wonder what is wrong
i have to always install the brand new RT kernel manually?
snapshot version of emacs-nox is not okay?
(purging that version and installing 21 or 22 results into no
emacs-nox existing)
HardyAlpha3 seems to have pulseaudio enabled as default
this has something to do with the error?

I had this problem, too...
Seems like jackd changed the default naming scheme of the out- and
inputs. It's now system:capture_1/2 and system:playback_1/2 instead of
the old sound-architecture-specific alsa_pcm/oss/etc.
Sc assumes the old naming so you could just set the connections yourself
using qjackctl or you could add this or create ~/.sclang.sc with
"SC_JACK_DEFAULT_INPUTS".setenv(
"system:capture_1,"
"system:capture_2"
);
"SC_JACK_DEFAULT_OUTPUTS".setenv(
"system:playback_1,"
"system:playback_2"
);

Yes, this could also be possible, thus turning alsa_pcm to
pulseaudio_pcm or something like this (assuming ubuntu uses a jack
version prior to the naming scheme change)
then just change sclang.sc to something according...

There is a very important (and bad) bug in JACK 0.109.0 that will affect
any attempts to use old patch/connection setups. a new release will be
made available ASAP.
8:33 p.m.
thank you all!
i sit in front of my linux machine once a week
so .. maybe by next time jack will be updated to solve the problem? ;-D
( if not will try what HTH told me ;-) )
but i still wonder what the SC@Ubuntu style will be in the near future.
if SC sticks to use jack insted of pulseaudio
a lazy set-up person like me will fall into trouble
when hardy becomes totally portaudio oriented?
or SC-ppl just disable pulse and just keep on using jack?
or something like jack@pulse may happen?
if yes to this
mpg321 with SC mixed via pulse may available?
is pulse a good thing for us? or more much more trouble making?

There is a jack module for pulse. I ahve installed it and used it
successfully in the past but it seems to slow things down. Maybe things
have improved since then, as I compiled and set it up middle of last
year sometime.

hmm
i wonder which direction SC-dev-ppl are aimed to..
if that jack module for pulse becomes good enough
we can mix SC,mpg321,yatm all together .. hoooray!
but SC directly to pulse might make things much simpler
at
http://wiki.laptop.org/go/Pulseaudio
i found CS doing things on pulse and it seems to be RT oriented
well yes i can't be greedy ... am not those dev-ppl
but want to get prepared for the things to come

Pulse is *great*. but .... its not JACK. if low latency matters, then
Pulse is (currently) not the answer. or not the best answer.

I doubt that we will change to add another audio backend.
There is enough to do as is on developing SuperCollider, and only a
few linux-developers on it.
As far as I know, most Ubuntu users of SuperCollider, are using the
Ubuntu Studio variant, which seems to have no problems with setting up
JACK.

ah yes
from Gutsy, UbuntuStudio is now like included in the original repo of Ubuntu
so i could apt-get almost everything i need for SC without doing
anything special
starting from a normal XubuntuGusty
(am doing very basic sine-wave things with SC so the old version is okay)
so i just became greedy and jumped to Hardy
to not make but apt-get some more extra apps
then came in was pulse ... but
since the problem i got seems to be only related to jack's bug
and pulse doesn't seems to prevent jack from working
hmmm doing the same as i was on Gutsy might be the way ... for a while ... ;-D
thank you for teaching!
thank you SC-dev-ppl !!!
