GNU Radio, One Step at a Time: Gnuradio error

Please I still have problems when I run a grc file.

I have loaded the grc file in the gnuradio and and do not get any

Red blocks but when I go to play it, I get errors.

Here is the log I see on the bottom side of gnuradio:

Any help?

Also please I have heard that I have to set the device name but did not understand how to do it.

arecord -L

and I got this result:
