This would allow to use closed-source apps that just support old-style OSS and don't work (correctly) over wrappers (some browser plugins, VMWare and others). In addition it could be used to get rid of sound-daemons, using dmix plugin and routing non-alsa apps through that virtual-pcm driver! Use: same as for virtualmidi, but for PCMs! ---------------------------------------------------------------------- ikonst - 06-09-05 18:14 ---------------------------------------------------------------------- I'm certainly interested in such a driver and would really love, when I'll have some more free time, to go into the kernel programming neceesary for it. BTW, Charles Samuels (of Noatun fame) once tried writing something like this (a driver that forwards sound to a user-space application which then can do whatever it wants with it) but I don't know how well he fared.
