Jack instead of ALSA

GNU Radio
1

Hello

Hoping anyone had gone through this before.
I am trying to make some experiments with jack audio in linux (Ubuntu
9.10), but so far, all I could get is Alsa.
I’m using the audio.sink and audio.source blocks, and have not yet
figured out a way for it to use Jack.
I have jack audio compiled in gnurario 3.2.2.
Any suggestions?

Thank you in advance,
Charles A. Herdt

Just in case someone else has the same problem:

if you need to force Jack audio:

from gnuradio import audio_jack

and on the source/sink linles, use audio_jack.source or
audio_jack.sink instead of audio.source and audio.sink.

Thanks to Oswald Berthold for the help.

Best regards,
Charles

Much easier to just edit ~/.gnuradio/config.conf
Add these three lines to the file:

[audio]
verbose = True
audio_module = audio_jack
