[LAU] RME HDSP Multiface and PulseAudio

I have, for the moment, my RME HDSP Multiface at home along with a nice pair of Sennheiser headphones. The headphones show up the shortcomings of the integrated audio I/F on the motherboard so I'd like to be able to route "normal" audio to the RME, e.g. use it for things like listening to music with rhtythmbox, which seems to mean persuading PulseAudio to output to it. So far the PulseAudio sound preferences does not see the HDSP even after restarting PulseAudio. The kernel module is loaded, the firmware loaded and the card works fine with jack and ardour. What do I have to do to persuade PulseAudio to see it? The distribution is Ubuntu 10.04. There is no /etc/asound.conf or .asoundrc file. I did try creating a .soundrc to enable ALSA applications to output to Jack in the hope this would cause PulseAudio to offer jack as an output option but this didn't seem to make any difference. Interestingly aplay -l shows the card and aplay -L does not: $ aplay -l **** List of PLAYBACK Hardware Devices **** card 0: DSP [Hammerfall DSP], device 0: RME Hammerfall DSP + Multiface [RME Hammerfall DSP + Multiface] Subdevices: 0/1 Subdevice #0: subdevice #0 card 1: NVidia [HDA NVidia], device 0: VT1708B Analog [VT1708B Analog] Subdevices: 1/2 Subdevice #0: subdevice #0 Subdevice #1: subdevice #1 card 1: NVidia [HDA NVidia], device 1: VT1708B Digital [VT1708B Digital] Subdevices: 1/1 Subdevice #0: subdevice #0 $ aplay -L pulse Playback/recording through the PulseAudio sound server front:CARD=NVidia,DEV=0 HDA NVidia, VT1708B Analog Front speakers surround40:CARD=NVidia,DEV=0 HDA NVidia, VT1708B Analog 4.0 Surround output to Front and Rear speakers surround41:CARD=NVidia,DEV=0 HDA NVidia, VT1708B Analog 4.1 Surround output to Front, Rear and Subwoofer speakers surround50:CARD=NVidia,DEV=0 HDA NVidia, VT1708B Analog 5.0 Surround output to Front, Center and Rear speakers surround51:CARD=NVidia,DEV=0 HDA NVidia, VT1708B Analog 5.1 Surround output to Front, Center, Rear and Subwoofer speakers surround71:CARD=NVidia,DEV=0 HDA NVidia, VT1708B Analog 7.1 Surround output to Front, Center, Side, Rear and Woofer speakers iec958:CARD=NVidia,DEV=0 HDA NVidia, VT1708B Digital IEC958 (S/PDIF) Digital Audio Output Any ideas, please?
