As a work-around I tried to use pipes:

load-module module-pipe-source  file=/tmp/tv.audio
source_name=pci_1131_7134_alsa_capture_0
load-module module-pipe-sink    file=/tmp/tv.audio

Eventhough the daemon loads, I hear nothing :(
The rest of my config:

#!/usr/bin/pulseaudio -nF
load-module module-alsa-sink sink_name=output
load-module module-alsa-source source_name=input
load-module module-hal-detect
load-module module-pipe-source  file=/tmp/tv.audio
source_name=pci_1131_7134_alsa_capture_0
load-module module-pipe-sink    file=/tmp/tv.audio sink_name=output
load-module module-esound-protocol-unix auth-anonymous=1
load-module module-native-protocol-unix auth-anonymous=1
load-module module-volume-restore
load-module module-rescue-streams
set-default-sink output
set-default-source input
.nofail

load-sample x11-bell /usr/share/sounds/gtk-events/activate.wav
load-module module-x11-bell sample=x11-bell
load-module module-x11-publish
load-module module-gconf
<END>

I figured it was worth a shot...
