Do you need to escape the space?
http://digitaldub.wordpress.com/2009/12/16/linux-audio-session-scripting/
"The backslash in the string USB\ Device:1 is an escape character. When
interpreted on execution, the character following the escape character (here
whitespace, wich happened to be part of the device name listed by aconnect)
will loose its special function as a seperator. An other option would be to
use quoting and write
aconnect 'USB Device':1 aeolus:0
Read more about quoting here if you want."
all the best,
