Re: [fluid-dev] ALSA Problem with libfluidsynth.so

[Tom M.]

I guess that you have libfluidsynth.so installed somewhere in /usr/lib/ and this one was compiled without alsa support. If this is the case, when starting ./fluidsynth_simple it doesnt find libfluidsynth.so in the current working directory and uses the one in /usr/lib/. Either remove that installation or set LD_LIBRARY_PATH like:

export LD_LIBRARY_PATH=/path/to/custom/libfluidsynth.so:$LD_LIBRARY_PATH

Or build fluidsynth_simple with a statically linked libfluidsynth.a of which you know it was compiled with alsa support.

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

Platform: Ubuntu 16.04.3 LTS, x86_64
