I guess we have different versions as I don't have any asoundrc files.  
I have a asound.conf file and I understand it that the system doesn't 
need this file so if I were you, I would rename that file and see what 
happens.  It sounds to me like asla is trying to process the stream and 
I don't think it should be.
