Broken pipe errors usually happens when the servers refuses or closes the
connection for some reason, you'll should check if there's no parameter
strange to the server like metadata or audio sample rate (try to resample
to 44100 hz for instance)
PS: beware of the "authentication basic" headers published here, they are
the user and password base64 encoded and easily decoded by anyone which
read this message
