Hi all,

After about the 10th time trying to install gnuradio on Ubuntu 14.04 i  
finally managed to get it working with some oot blocks.

Only problem now is the audio sink doesn’t produce a clean output say at  
1  
khz its very intermittent, sounds more like a square wave or something  
weird. I have messed around with gr-audio.conf but still produces the  
same noise.  
Im running Ubuntu 14.04 on a vmware mac

any help would be greatly appreciated

thanks
