Re: [Discuss-gnuradio] audio_alsa_sink problem

[davek]

im having the same problem
dial tone in GRC crashes with the same error
but the python dialtone example works fine
running svn trunk on ubuntu 8.10 64bit standard install with a
gigabyte ga-ep45-ud3r onboard audio...
if you figure it out let me know...
thanks..
