Java allows for multiple sound cards to be used. If I install multiple sound cards I can in Java Sound select which one I want to use for input and output. Java Sound on Linux does also allow for sound cards with multiple inputs and outputs. I have a M-Audio Delta 1010LT installed with 8 analog inputs and 8 analog outputs. The problem is that ALSA and JavaSound only allow me to open one DataLine, but this one DataLine can have up to, I think ,10 input channels and 12 output channels (besides the analog inputs and outputs there are digital inputs and outputs). What I however would like would be to have 8 separate mono devices instead of one multichannel device. On the Java Sound Resources page one of the administrators writes that a multichannel sound card can be spilt using the ALSA configuration files. I tried to ask how this could be done, but no one answered. My tests with a single stereo sound card showed that ALSA on Linux performs better than DirectSound on Windows. klondike wrote: > First of all bear in mind that by some strange reason, Sun's Java > doesn't use the default card with alsa but hw:0,0, that's why you must > use aoss son java uses oss and interfaces with the alsa card.
