I can confirm that this work fine with my dolby decoder receiver. I needed to add the mmap=0 and fragments=6 switches to avoid any audio stutter. When using this method, pulseaudio consumes 20% of my 2.4G P4 processor while idle and 40% while playing a stream via rtp_recv. I assume this extra processor requirement is actually being consumed by the a52 encoder in the alsa plugin?
