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 mcarans):
Finally I got it all working including a52 Pulseaudio profiles!
These are the steps on 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(strcmp(u-device_name, a52) == 0) {
pa_sink_set_max_rewind(u-sink, 0);
} else {
pa_sink_set_max_rewind(u-sink, u-hwbuf_size);
}
}}}
3. Add Colin's patch:
{{{
if (PA_UNLIKELY((sframes = snd_pcm_mmap_commit(u-pcm_handle,
offset, frames)) 0)) {
+if (!after_avail (int) sframes == -EAGAIN)
+break;
+
if ((r = try_recover(u, snd_pcm_mmap_commit, (int)
sframes)) == 0)
continue;
}}}
4. Compile and install Pulseaudio with udev support: make and sudo make
install
5. Edit /usr/local/share/pulseaudio/alsa-mixer/profile-sets/default.conf:
change a52:%f to a52
6. Copy /etc/pulse/daemon.conf to ~/.pulse/daemon.conf and ensure it has
uncommented: default-sample-rate = 48000
7. Edit ~/.asoundrc
8. Put in it:
{{{
# Encode AC3 - Directly on hardware
pcm.Filter_A52Encode {
type a52
bitrate 448
channels 6
card NVidia
}
# Rate Converter to 48kHz, needed for some applications
pcm.a52 {
type rate
slave {
pcm Filter_A52Encode
rate 48000
}
}
}}}
9. Change NVidia to your card's name from: cat /proc/asound/cards
10. sudo alsa reload
11. 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 ...
12. pulseaudio -k
13. pulseaudio -D

Comment(by mcarans):
I forced Pulseaudio not to rewind using:
pa_sink_set_max_rewind(u-sink, 0);
This seemed to fix it.
timeout=0 is no longer needed in default.pa: default.pa: load-module
module-suspend-on-idle # timeout=0
However, there is still a need for a rate converter in asoundrc: # Rate
Converter to 48kHz, needed for Pulseaudio it seems pcm.Filter_RateConvert
{
type rate slave {
pcm Filter_A52Encode rate 48000
}
}

Comment(by mcarans):
I have found something that works for a while.
I add to .asoundrc:
{{{
# Rate Converter to 48kHz, needed for Pulseaudio it seems
pcm.Filter_RateConvert {
type rate slave {
pcm Filter_A52Encode rate 48000
}
}
}}}
and in default.pa:
{{{
load-module module-alsa-sink device=Filter_RateConvert rate=48000
channels=6 tsched=0 sink_properties=device.description=SPDIF
sink_name=SPDIF
}}}
Music plays through AC3 via SPDIF through Pulseaudio and Alsa, but when I
close the application (eg. Rhythmbox music player), the SPDIF output
disappears.
I have attached a new back trace: pulseaudiooutput_rateconverter.txt
I think it's here where the Filter_RateConvert sink gets unloaded for some
reason:
{{{
I: client.c: Freed 1 Rhythmbox
I: protocol-native.c: Connection died.
I: module.c: Unloading module-alsa-sink (index: #4).
D: module-always-sink.c: Autoloading null-sink as no other sinks detected.
}}}
How can I prevent this unloading?
