You can specify that you only want the audio from a source, not sure how
much delay/processing that introduces

we also use Darkice deb multimedia but nevertheless we suffer regular
crashes, in the next 60 days we also plan to test liquidsoap starting
with reading the docs, anyone know wether in Liquidsoap the audio on a
videostream can be processed seperately (without to much latency)?

Memory leak in which version? FWIW our streaming server has been
running for months without issue (Debian Squeeze AMD64 with darkice
version 1.2-dmo2 from the deb-multimedia repository):
http://www.deb-multimedia.org/dists/testing/main/binary-amd64/package/darkice-full
That said, I really want to check out liquidsoap based on all the
feedback on the list.

Subject: Re: [RDD] ALSA-JACKD2-DARKICE
found post in one of the ubuntu forums darkice has a memory leak
supposedly and that appears to be reason for it not running extended
periods without having to be restarted.

Thanks for the reply Karl, here is some further info re ur query:
with jack stopped & quit and alsamixer set up both mic and line
inputs are live to speaker outputs.
with jack running and monitor1 & monitor2 connected to darkice and
meter nothing is streamed but still heard over localhost speakers.
front mic is live and set as capture device; when capture device is
selected in patchbay and sent to meter and darkice audio is
streamed by icecast and when tone is applied to line in also is
streamed.
when the mic is removed so that local speakers don't feed back
through, the stream being sent still include the tone from the line
in. so despite jack only connecting capture audio from the 'no'
microphone, the MASTER mixer output still appears to be fed out on
the capture plugs in jack.
The master output from localhost would contain mix of line and mic
but the darkice jackpatch is capture device only NOT the master
mixed output according to jack patch setup.
To make matters worse when I stop any audio connections, and return
to see alsa mixer, all are muted suddenly except mic audio and line
AND automute is set to OFF.
doesn't make sense logically from what I understand of the info re
jack and alsa online and in RD wiki/lists; maybe I have got it
wrong somehow
Possibly changing to another linux box with multiple sound cards
might help
system in the patch window shows capture 1 & 2 which are
configurable under alsamixer to beith either one of two mics or
else line in. the monitor 1-6 I assume are the surround sound
outputs with 1 & 2 being front 2ch stereo; does this mean that
there has to be speakers connected to these jacks on the pc in
order to here anything on playbacks 3-6 in jack patchbay?

Does this happen even when jackd isn't running? If so, your sound
card might be internally mixing the audio input into the output.
You'll need to use alsamixer (or something similar) to fix this.
ALSA apps can use JACK as a virtual sound card. The apps do not
need to be JACK-aware.

got all working now with one strange occurrence.
with audacity, alsaplayer, ardour,aqualung and darkice all up
and running and showing their resources in jack connections as
one would expect plugging a 1000 hz tone into the line in
immediately causes tone output to speakers without being patched.
Using audacity to select the line input as it's source the
outputting it through Audcity's jack resources works ; can't
explain why it appears alsa is driving the speakers directly
when jack is running??
Can anyone explain that?
Thanks
