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

That said, I really want to check out liquidsoap based on all the

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.

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?

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.
