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?

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..

Using plughw:0,0 does not change anything. The error is the same.

When trying to use audio sink in GRC I get following error:

The audio test samples in gnuradio-examples/python/audio do work with
no problems.
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?
