I did it and, with "signed=true", it fails with "erroneous pipeline: 
could not link audioresample0 to alsasink0" message. Removing the 
"signed=true", it behaves apparently as expected (without any error 
messages), but no sound comes out of the speakers. I attach both 
debug.log files for your analysis.

Thanks!
Rodrigo
