[Discuss-gnuradio] example audio_copy and Sound Blaster Vibra16C

[Patrick Strasser]

Hello!

I have troubles running the audio_copy example:

$ ./audio_copy.py
audio_alsa_source[hw:0,0]: unable to support sampling rate 48000
  card requested 44100 instead.
audio_alsa_sink[hw:0,0]: failed to find acceptable formatTraceback (most 
recent call last):
  File "./audio_copy.py", line 53, in ?
    fg = build_graph (options.input_device, options.output_device)
  File "./audio_copy.py", line 32, in build_graph
    dst = audio.sink (sampling_freq, output_device)
  File "/usr/lib/python2.3/site-packages/gnuradio/audio_alsa.py", line 
192, in sink
    return _audio_alsa.sink(*args)
RuntimeError: std::runtime_error

I'm running Debian with newest (2.5-5) packages and gr_audio_alsa.
I had this problem before with a Soundblaster Live! card, so i switched 
to a Sound Blaster Vibra16C (id:CTL0070).

I've read some time ago that some reports from alsa and real 
capabilities don't match. Is there anyone having experience with alsa? 
Where can I find out more about my card (some diagnose tools or /proc, 
/sys entries)?
