No audio output using Precise due to pulseaudio?

[Ralf Mardorf]

I've got a RME HDSPe AIO card for audio IOs and MIDI and I've got 2
TerraTec EWX 96/24 for MIDI.

The first and only audio test failed.

I played a Youtube music video with Firefox and there's no audio output.

The pulseaudio crap does show my TerraTec cards only. I rebooted until
the RME card became hw:0, but this doesn't improve anything.

How do I get audio output?

Regards,
Ralf
