Re: [Fluid-dev] multiple sound cards

[Garett Shulman]

Markus & Josh, Thank you very much for your replies. The -o 
audio.alsa.device=hw:1 is exactly what I needed to know. However, my 
m-audio delta 2496 card seems to give fluidsynth trouble with this. My 
SB Live 512 works fine with this syntax. I loaded the ice1712 module 
first so that the 2496 will be card0. with just -alsa fluidsynth loads 
fine. however, with -alsa -o audio.alsa.device=hw:0 fluidsynth exits 
with: fluidsynth: error: Failed to find a workable audio format Failed 
to create the audio driver. -alsa -o audio.alsa.device=hw:1 works fine. 
With just the -alsa fluidsynth loads with: ** Using format s16, rw, 
interleaved. I will include the corosponding lines of straces for the 
mentioned commands for the lines just prior to fluidsynth crashing. 
Again, I REALLY appreciate any suggestions anyone might have. Thanks a 
lot. -Garett
