Hi all

I’m working with openSUSE 11.4 (2.6.37.1-1.2) KDE desktop and latest  
stable  
gnuradio version ./configure make and make install show me no errors and  
modules  
that I need are configured however dial\_tone.py example fails. It never  
happened  
to me with openSUSE 11.1 and gnuradio 3.1.3

What can I do?  
Juan Q.

I’m also running OS11.4.  
OS11.4 KDE by default uses pulseaudio as audio-system which might cause  
some trouble there :), especially if you haven’t installed ALSA or OSS.  
If you change to ALSA direct, you’ll have the problem that GNURadio  
wants the audio hardware exclusively for itself, which collides with KDE  
notification and (if you use it) speech-dispatcher.  
My temporary solution is that I use ALSA and have GNURadio use another  
output of my (furtunately 5.1) soundcard which is not used by anything  
else.

Me, I just dedicate a sound card to Gnu Radio. They’re fairly cheap  
these days. USB sound cards (48KHz) can be had for  
about $10.00 on eBay.
