Linux 2.4 Sound Changes2000-September-25Christoph Hellwig, <hch@infradead.org>=== isapnp supportThe Linux 2.4 Kernel does have reliable in-kernel isapnp support.Some drivers (sb.o, ad1816.o awe_wave.o) do now support automaticallydetecting and configuring isapnp devices.=== soundcard resources on kernel commandlineBefore Linux 2.4 you had to specify the resources for sounddriversstatically linked into the kernel at compile time(in make config/menuconfig/xconfig). In Linux 2.4 the ressources arenow specified at the boot-time kernel commandline (e.g. the lilo'append=' line or everything that's after the kernel name in grub).Read the Configure.help entry for your card for the parameters.=== softoss is goneIn Linux 2.4 the softoss in-kernel software synthesizer is no more aviable.Use a user space software synthesizer like timidity instead.=== /dev/sndstat and /proc/sound are goneIn older Linux versions those files exported some information about theOSS/Free configuration to userspace. In Linux 2.3 they were removed becausethey did not support the growing number of pci soundcards and there weresome general problems with this interface.
