[Discuss-gnuradio] wav file source question

[Baokun Liu]

Hi guys,

I am playing with gnuradio companion. I have a question on wav file.

I play like this first (the samp_rate set to 32k)

Audio Source ---> Wav File Sink;

I save the file as test.wav. It sound well.

Then, I play the file back (samp_rate is 32k).

Wave File Source ---> Audio Sink;

The error comes as: WAV file does not contain any samples.

Could anyone point out the problem? How could I use the 'wav file source' block?

Thanks,

Baokun
