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?
