In my PC system, I have two Terratec Aureon Fun sound cards (C-Media sound chip). They both were accessible in 9.04, but after upgrading to 9.10, there is no way to achieve them. I try to make use of the Sound Preferences dialog to control input/output, but nothing is visible here. On my laptop I did the upgrade too, and there I see the two sound devices being displayed.

I'm developing an program based on Java Sound, as well as this cannot either find any DirectAudioDevice mixers any longer, so I assume this must have happened quite deep down. The gamier application do not illustrate them also. Yet, lspci lists both soundcards. Some bugs with the alsa driver?
