[Discuss-gnuradio] Transmitting Audio Stream Using tx_voice.py

[meggahertz]

I need some help using the tx_voice.py. I am trying to transmit an audio stream 
preferably coming from the computer's soundcard microphone input. I tried 
running the following command:

sudo ./tx_voice.py -f 99.3M

The following is what I get:

"992 items of size 33. Due to alignment requirements
   4096 were allocated.  If this isn't OK, consider padding
   your structure to a power-of-two bytes.
   On this platform, our allocation granularity is 4096 bytes."

Does nothing for a little bit but then gives:
"snd_pcm_readi error" or something. 


I am using default "hw:0,0" because I tried using audio_play.py with hw:0,0 and 
I could hear the file therefore, I believed it is a valid device location for 
the soundcard. I am using a Basic TX right now to perform this. I would 
eventually like to receive the audio using an FM radio and I believe GMSK 
modulation can would make it able to be listened on an FM radio. Therefore, I 
am trying to use the default modulation. Has anyone tried something like this? 
I heard a few threads with similar information but couldn't get a clear idea. 

Thank you in advance,
Omar
