Ravi, All of these questions have been answered in the past, and are in the list archives:

The problem is that your soundcard doesn't support the 32000 samples per second rate. The solution is to add "-O plughw:0,0" to the end of your command line (without the quotes), which causes ALSA to resample the output to be at a compatible sample rate. > > please get back to me regarding this > Most of the people answering questions on the list are volunteers (myself excluded, of course). Statements like this imply that you are "owed" an answer, and this makes it _less_ likely that you will receive one.
