Hi, I run Fedora 10 on a Sony Vaio Z laptop. I have a RME Multiface that connects to the machine via the express32 card bus. Fedora recognizes the audio interface, the interfaces control panel appears in the Applications >Sound & Video tab and I can chose frequency etc at will - there is no error message there. In the Preferences >Hardware >Sound >Devices the interface appears (with ALSA in brackets at the end) as well. However when I click "Test" I get an error message audiotestsrc wave=sine freq=512! audioconvert! audioresample! gconfaudiosink: could not open audio device for playback. This error persists regardless of sampling frequency. I have no clue how to go any further. I disabled pulse audio in the Preferences >Personal >Sessions settings but I wonder if it is not better to get rid of pulse audio altogether - I heard of conflicts between alsa and pulse audio. If it is preferable to remove pulse audio from the system I wouldn't know yet how to do so. Any suggestion is largely appreciated. I have SELinux disabled.
