Works out-of-the-box with the snd_emu10k1 (EMU10K1_Audigy) kernel module. It can be used as a MIDI playing card. You might need to `start the sequencer' in YaST -- Hardware -- Sound -- (Click/highlight CT4832 SBLive! Value) -- Other -- Start Sequencer.
I had a problem with a lot of static/white noise. This was so bad, that it was not possible for me to increase the Master and PCM volume to maximum at the same time. It may even have damaged one of my speakers. This problem was solved turning off `microphone capture' via the sound mixer panel. Just muting the microphone was not good enough. Trying to tick the `capture' box off also does not work, I needed to tick the `capture' box on another sound device e.g. CD input.
To be used as a MIDI playing device, soundfonts need to be loaded. Soundfonts are provided on the Soundblaster installation disk, either the Windows 98 or Windows2000 disk. YaST can be used to install the soundfonts (same menu as above, -- Other -- Install Soundfonts), but has a nasty habit of crashing. The provided soundfonts are not very good, either. The largest one provided is 8 megabytes in size. By contrast, the FluidR3 soundfont is almost 150 megabytes in size, and sounds much better! All is not lost, however, as the Soundblaster Live! card can use the FluidR3 soundfont!
First you need to get the better soundfont. Do a Google search for `Fluid R3 soundfont', or you can see the instructions on the first page of Ubuntu -- Getting MIDI to work.
