Ever since version 1.1 of PulseAudio was released, remote audio stopped working for me. Basically, the tunnel created by enabling "Detect native remote PulseAudio sinks" in paprefs on the client side immediately crashes the PulseAudio server on the remote host. I reported the issue at Free Desktop bug #49681. The issue still exists in version 2.0, which is what Debian's next stable release is supposed to ship (and in 2.1, available via the experimental repository). This essentially means that I cannot upgrade my hosts to Wheezy without losing my remote speakers. Would anybody knowledgable enough with PulseAudio internals be able to help me track down the cause of this bug?
