Can't create more than one pulseaudio jack sink or source

[bartok]

Hi.

I know, it's preferable to manage without of pulseaudio and stick to jack/alsa. However , I need to use a voice effect (voice distortion) that needs pulseaudio.

The problem is, I need more than one pulseaudio jack sink, however the system only lets me to create one. After that, when running

Code: Select all

foo@bar:~#/$ pactl load-module module-jack-sink client_name=newsink

it says

Code: Select all

 "Failure: module initialization failed"

. I am using mainly cadence to manage Jack2. Tried starting jack from qjackctl with the same result. Tried root, not root, same result.

This is on debian jeezy stable "upgraded" to kxstudio.

How may I unlock this?

Thanks in advance

I definitely not a specialist of that question, but I don't know how it could be possible. With all the plugins available, are you sure that you can't use a more 'academic' way to do what you want ?

You shouldn't load the module twice, but give the channel key when load the module:

Code: Select all

pacmd load-module module-jack-sink channels=2 

pacmd or pactl as you desire.

Thank you. It didn't work though. Same error with pactl. With pacmd got "daemon doesn't respond".

edit: learned that this was doable only in pulseaudio versions above 6.0. Upgraded and worked

What do you mean by "more academic"?

I need a a program or plugin that allows me to modify/distort voice on the fly and record that on ardour on a desktop record software, or live broadcast.

Do you know any plugin that can do specifically that?

I said 'academic' (Sorry, the word is probably not acurate) because I don't think that mixing Jack and pulseaudio is a good thing.
There are plenty of plugins available with jack. I'd be suprised that you could'nt find something for you in that bag.

And you could also record in pulseaudio the track the way you want, and play it with jack after.

Anyway, for what you want, your way is always the best.
