No audio devices found for Ubuntu with QAudio classes

Ubuntu 9.04 does not list a "default" entry for sound devices. The alsa based qaudio classes use this "default" device or "default:CARD=" device entries so no input/output devices are found. Here is a sample from "aplay -L" on Fedora:

default:CARD=SI7012
SiS SI7012, SiS SI7012
Default Audio Device
front:CARD=SI7012,DEV=0
SiS SI7012, SiS SI7012
Front speakers
default:CARD=Headset
Logitech USB Headset, USB Audio
Default Audio Device
front:CARD=Headset,DEV=0
Logitech USB Headset, USB Audio
Front speakers

On Ubuntu, the same looks like:

front:CARD=Intel,DEV=0
HDA Intel, ALC888 Analog
Front speakers
front:CARD=Headset,DEV=0
Logitech USB Headset, USB Audio
Front speakers

The qaudio classes search for the "default:" entries and therefor no devices are found. This is with the current GIT tree for 4.6.
