I haven't had the need to try audio from PC to N800 but if you have any local files on your PC, you might be able to run some kind of supported streaming audio server on your PC and play it on your N800. I sometimes transfer files (such as PDF) from PC to N800. I just have the Filezilla FTP server running on the PC and shared a folder where I want to transfer the files from. Then, on the N800 browser, you just type ftp://192.168.1.150 or whatever your PC's IP address is.
