[LAU] [NEWBIE] help needed for using SoX with Jack.

Hello,

I'm only 3 months old newbie with Ubuntu/Linux, so please be gentle...

I'm using Ubuntu 10.10 and I'm trying to use SoX with Jack audio driver.
(while I'm using Jack for all the other audio applications)

But SoX just won't output any sound. I've tried some options described in
the manual (such as set AUDIODRIVER or play -t alsa....etc.)but it won't
give me any errors, just not output audio.

It's very frustrating. I can't even play an audio file...

here's the information when I start my jackd with command: 'jackd -R -d
alsa -s -r 48000 -X seq'

Memory locking is unlimited - this is dangerous. You should probably alter
the line:
@audio - memlock unlimited
in your /etc/limits.conf to read:
@audio - memlock 737577
no message buffer overruns
JACK compiled with System V SHM support.

creating alsa driver ...

control device hw:0
configuring for 48000Hz, period = 1024 frames (21.3 ms), buffer = 2 periods
ALSA: final selected sample format for capture: 32bit integer little-endian
ALSA: use 2 periods for capture
ALSA: final selected sample format for playback: 32bit integer little-endian
ALSA: use 2 periods for playback

How can I run SoX command without quitting my jack environment?

I'm using Supercollider with jackd, and my plan is manipulate my samples
with SoX while I'm making music with supercollider.
so it'll be crucial for me that I won't need to quit my current jackd
environement optimized for supercollider...

any help would be appreciated.

thank you.
