Just wanted to follow up with some info on FPU support for that system. It sounds like the Raspberry Pi does have hardware FPU support. However, it may be that FluidSynth has not been compiled with it. From the 2nd stackexchange answer ( http://raspberrypi.stackexchange.com/questions/545/does-th

Hello, Thank you for your response. 1. Actually, I did not intend to say that ALSA and JACKD were giving me the same error in FluidSynth. The "fluidsynth: error: The audio device error: Input/output error" would appear when selecting ALSA, a few seconds after the initialization of FluidSynth (an

Hello, I find it interesting that you get the same error with jackd. In that case does FluidSynth quit with the same error or does jackd quit? Sometimes there are limitations with audio drivers in regards to sample rate, buffer sizes, etc. You may want to try 48KHz or 44.1KHz (depending on whic
