Re: [Discuss-gnuradio] A problem with ALSA

[keval]

Greetings.
I had the same error messages, but followed the instructions at
http://ubuntuforums.org/showthread.php?t=32063 
and everything now seems to work.  I'm too new to all this to explain how or
why it solved the problem, but suggest you give it a try and see if your
apps will run.
All the best,
Kevin
