[Discuss-gnuradio] error using audio.source() (alsa)

[Meenal]

Hi all,
I am trying to read I/Q signals from audio line-in. I am using
audio.source for this purpose. I get the following error. I am
using alsa.
--------------------------------------------------------------------------------------------------------------------------
address@hidden python fmrx.py
audio: using audio_alsa
audio_alsa_source[hw:0,0]: set_periods failed: Invalid argument
Traceback (most recent call last):
  File "fmrx.py", line 105, in ?
    main ()
  File "fmrx.py", line 99, in main
    fg = build_graph ()
  File "fmrx.py", line 22, in build_graph
    src = "">
  File
"/usr/local/lib/python2.3/site-packages/gnuradio/audio_alsa.py",
line 210, in source
    return _audio_alsa.source(*args)
RuntimeError: std::runtime_error

Any ideas?

Many thanks,
Meenal
