[pulseaudio-discuss] Problems with ASUS Xonar D2X & PulseAudio card detection.

[Russell Treleaven]

make a safety copy of /etc/pulse/default.pa
edit the file to comment out the following lines like this

#load-module module-udev-detect
#load-module module-detect

add the following lines immediately following the ones you commented out

load-module module-alsa-sink device=hw:<your_card>,<sink_index>
sink_properties="your_sink"
load-module module-alsa-source device=hw:<your_card>,<source_index>
source_properties="your_source"

You can discover the value for <your_card>, <sink_index> and <source_index>
via `aplay -l` and `arecord -l`

restart pulseaudio
`pulseaudio -k`

verify it worked
`pactl list sinks`
`pactl list sources`

Not a fix but it is a workaround
