Hi! You are getting the error message because the hw plugin doesn't have the option to set the buffer size (that what it's saying :-P). You do have the possibility to set the buffer size with the dmix plugin. http://www.alsa-project.org/alsa-doc/alsa-lib/pcm_plugins.html#pcm_plugins_dmix http://alsa.opensrc.org/Dmix I used this option with my sound card, but I had to use dmix for hardware mixing anyway. I don't know whether you have to use dmix, maybe you can do it with the slave plugin, too. The documentation looks like if you could, I just didn't use it yet. http://www.alsa-project.org/alsa-doc/alsa-lib/pcm_plugins.html#pcm_plugins_slave Hope this helps...
