[Discuss-gnuradio] Can't get input from sound card. |

Greetings all,
I'm trying to interact with the sound card. The example programs, such
as dial_tone.py and dialtone_v.py, that output audio work fine. But I
don't seem to me able to get any data from the audio card using such
programs as audio_to_file.py or audio_fft.py.
When I run
[]# audio_fft.py -S
I get the following message:
WARNING **: IPP request failed with status 1030
I don't know if this is an issue or not. I searched the archives and it
appears that many folks have seen it without any adverse affects.
However, I don't seem to actually get any data. The scope runs, but it
is flatlined. I know the soundcard and the microphone are good. I've
tried both the mic input and, out of desperation, the line input jack.
Similarly, when I ran the audio_to_file.py program, it generates a file
of the right length, but when I play it back I hear nothing.
Any ideas?
TIA
