[fluid-dev] ALSA Problem with libfluidsynth.so

[mike]

Hi All, I successfully used 'cmake' and 'make' to produce the fluidsynth 
executable. Running

./fluidsynth -a alsa FluidR3_GM.sf2 LUTE.mid

played the MIDI file perfectly.

I then compiled the example fluidsynth_simple.c, and linked it against 
libfluidsynth.so
The only change I made to fluidsynth_simple.c was to add the line 
selecting ALSA before selecting the audio driver.

        fluid_settings_setstr(settings, "audio.driver", "alsa");
        adriver = new_fluid_audio_driver(settings, synth);

Ran it:- ./fluidsynth_simple FluidR3_GM.sf2

This is the result:

fluidsynth: warning: Failed to pin the sample data to RAM; swapping is 
possible.
fluidsynth: error: Couldn't find the requested audio driver alsa. Valid 
drivers are: file, oss.
Failed to create the audio driver.

Any help in using ALSA with the library would be appreciated.

Regards, Mike
