1Linux 2.4 Sound Changes 22000-September-25 3Christoph Hellwig, <hch@infradead.org> 4 5 6 7=== isapnp support 8 9The Linux 2.4 Kernel does have reliable in-kernel isapnp support. 10Some drivers (sb.o, ad1816.o awe_wave.o) do now support automatically 11detecting and configuring isapnp devices. 12 13 14 15=== soundcard resources on kernel commandline 16 17Before Linux 2.4 you had to specify the resources for sounddrivers 18statically linked into the kernel at compile time 19(in make config/menuconfig/xconfig). In Linux 2.4 the ressources are 20now specified at the boot-time kernel commandline (e.g. the lilo 21'append=' line or everything that's after the kernel name in grub). 22Read the Configure.help entry for your card for the parameters. 23 24 25=== softoss is gone 26 27In Linux 2.4 the softoss in-kernel software synthesizer is no more aviable. 28Use a user space software synthesizer like timidity instead. 29 30 31 32=== /dev/sndstat and /proc/sound are gone 33 34In older Linux versions those files exported some information about the 35OSS/Free configuration to userspace. In Linux 2.3 they were removed because 36they did not support the growing number of pci soundcards and there were 37some general problems with this interface. 38 39 40
