The audio sink in GRC has 3 parameters: sample_rate, device_name, ok_to_block The generated code looks like this: audio.sink(sample_rate, device_name, ok_to_block)If entering plughw:0,0 for the device_name does not fix the problem, I am unsure about what is wrong... GRC generates the code, we can always compare this to the code in a working example.
Is the GRC block missing an extra (4th) parameter to audio.sink? -Josh davek wrote:
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..

I tried to google for further information, but found only the archive of this mail list suggesting to search the net for the solution. Looks like a recursive solution for me. :-)Thanks for searching first!I am new to gnuradio stuff so it may well be my ignorance causing this, but I can not find any tutorials or manuals or documentation especially for the GRC.I've seen the error before (but not on my h/w). Can you try using plughw:0,0 instead of hw:0,0 and see if that changes anything?
