Comment(by mcarans):

 New versions of Pulseaudio will be patched, but in the meantime, here are
 the revised steps for Ubuntu Lucid 10.04 LTS:

 {{{
 1. Open from Pulse source code: src/modules/alsa/alsa-sink.c

 2. Replace: pa_sink_set_max_rewind(u->sink, u->hwbuf_size); with:
 if (pa_alsa_pcm_is_hw(u->pcm_handle)) {
 pa_sink_set_max_rewind(u->sink, u->hwbuf_size);
 } else {
 pa_log("Disabling rewind for device %s", u->device_name);
 pa_sink_set_max_rewind(u->sink, 0);
 }

 3. Replace: pa_sink_set_max_rewind_within_thread(u->sink, u->hwbuf_size);
 with:
 if (pa_alsa_pcm_is_hw(u->pcm_handle)) {
 pa_sink_set_max_rewind_within_thread(u->sink, u->hwbuf_size);
 } else {
 pa_log("Disabling rewind_within_thread for device %s",
 u->device_name);
 pa_sink_set_max_rewind_within_thread(u->sink, 0);
 }

 4. After line: if (PA_UNLIKELY((sframes =
 snd_pcm_mmap_commit(u->pcm_handle, offset, frames)) < 0)) { add:
 if (!after_avail && (int) sframes == -EAGAIN)
 break;

 5. Compile and install Pulseaudio with udev support

 6. Copy /etc/pulse/daemon.conf to ~/.pulse/daemon.conf and ensure it has
 uncommented: default-sample-rate = 48000

 7. Edit ~/.asoundrc and put in it:
 pcm.a52 {
@args [CARD]
@args.CARD {
type string
}
type rate
slave {
pcm {
type a52
bitrate 448
channels 6
card $CARD
}
rate 48000 #required somehow, otherwise nothing happens in
 PulseAudio
}

 8. sudo alsa reload

 9. Make sure you do not have a ~/.pulse/default.pa or if you do, that it
 is using load-module module-udev-detect to load Alsa sinks not load-module
 module-alsa-sink ...

 10. pulseaudio -k and pulseaudio -D
 }}}

Comment(by coling):

 [3ede7e4] and [cb55b00] along with a suitable alsa config seem to solve
 this.

 Alsa config is:
 {{{
 pcm.a52 {
@args [CARD]
@args.CARD {
type string
}
type rate
slave {
pcm {
type a52
bitrate 448
channels 6
card $CARD
}
rate 48000 #required somehow, otherwise nothing happens in
 PulseAudio
}
 }
 }}}
