[pulseaudio-discuss] Ubuntu or PulseAudio Bug?

Following is one of the last attempts I made. I've experimented with
just the onboard IntelHDA and with just the ancient Ensonic PCI. I've
verified that the ladspa filter works using the 'applyfilter' and
'analyzefilter' ladspa tools.

I have also let module-udev-detect find the card(s) and used pacmd to
add the filter manually with the same symptom of sound no longer coming
from the speakers.

I was thinking that I should try to use module-pipe-sink/source and
applyfilter to try and see if that works, but I haven't figured out how
to do so yet.
