Hello - Thanks, the installation of libasound2-dev worked; fluidsynth is now playing perfectly.

cmake does complain:
ALSA:                  no

So it looks like you are not having the libasound2-dev package installed. Hard to tell without the full cmake log though. The same problem should also arise if you attempt to build fluidsynth 1.1.6.

Note that it neither finds the LADSPA dev files:
LADSPA support:        no

    Hello,

    I cannot run fluidsynth using ALSA

    A few details:

    Platform: Ubuntu 16.04.3 LTS, x86_64
    fluidsynth: 1.1.7
    cmake: cmake -DCMAKE_INSTALL_PREFIX=/usr -Denable-ladspa=1

    cmake yields :
    **************************************************************
    Summary:
    Build type:            RelWithDebInfo
    libsndfile:            no (raw audio file rendering only)
    D-Bus:                 no
    PulseAudio:            no
    JACK:                  no
    ALSA:                  no
    PortAudio:             no

    Trap on FPE (debug):   no
    Check FPE (debug):     no
    **************************************************************

    cmake does not complain about finding ALSA, and will yield the
    same even if I change -Denable-ladspa=1 to -Denable-alsa=1

    after a successful 'make':

    ./fluidsynth -a alsa FluidR3_GM.sf2 LUTE.mid
    yielded : fluidsynth: error: Couldn't find the requested audio
    driver alsa. Valid drivers are: file, oss.

    ./fluidsynth -a file FluidR3_GM.sf2 LUTE.mid
    yielded : fluidsynth.raw, which was playable by Audacity. Also
    complained about MIDI.

    Any help would be much appreciated

    Regards, Mike
