I've compiled miniaudicle with jack enabled, and i get this message while trying to run a chuck script.

[fm.ck]:line(4): ugen's of type 'DAC' have no input - cannot => from another ugen...

Is there any reason i'm getting this? Also I've tried miniaudicle alsa, and it occasionally displays a rtpapialsa callback error or just hangs on adding a shred. Incidentally is there any reason why the commandline switch bufnum isn't ever passed to the chuck vm? I've found that using chuck on the commandline, i needed to specify the number of buffers to be 4 for it to work, which doesn't work in miniaudicle.

There's a possibility that it's my sound drivers that are a problem. I'm running ubuntu studio 7.04 on an alc888 on board sound.

Edit: Just in case someone reads this in the future, miniAudicle version is 0.1.3.7 (alpha) which comes with chuck 1.2.0.8 (dracula)

Looks like the oss version works though.

i was using chuck and miniAudicle in debian/ubuntu linux on some older laptop computers also.
and had the same problem.

so i had to use OSS then.
the way to solve problem might be around ALSA and the soundcard.
(i'm still very confused with alsa and incoporating soundcards and audio interface -_-)

Somehow i think it's just a question of configuration of the soundcard. The only problem is how to do it, so that sucks Smile

is "sudo alsaconf" and using "asoundconf" works for you?
(for choosing a default card & and preparing a driver for it)

I'll try that some other day, i'm booted into windows at the moment, which incidentally has miniaudicle running perfectly... hahahhahahha ...... that's hysterical laughter btw.

Anyhow the last time round i checked on my other version of ubuntu, alsaconf seemed to think my soundcard was the alc883 and not the 888.

But i would really like a technical explanation for this
[fm.ck]:line(4): ugen's of type 'DAC' have no input - cannot => from another ugen...

when using jack, since jackd seems to be running all well and good.

dac has no input?
for me it means jack can't find a way to output to the soundcard. hmm..
(i once got that..)

Now I'm lost, I thought "dac" *wasn't* a Ugen and so doesn't follow the Ugen's style of capitalised naming (it's instead a class that abstracts the sound-driver, seems like subtle difference to me...).

"[fm.ck]:line(4): ugen's of type 'DAC' have no input - cannot => from another ugen... " is quite a strange message then.

Maybe it's time for a mail to Ge.

It's not so strange to me.
I've got that quite a few times.
it's just when the sound system isn't set to the dac with "output"

for example.. failed initialization of ALSA..
and it happened that way also if i use 'Digital Camera' (with microphone) as DAC
(surely it doesn't have a sound output)

so it's just because the program can't connect to a right dac
or the system is not correctly configured.
