| === isapnp support | |
| The Linux 2.4 Kernel does have reliable in-kernel isapnp support. | |
| Some drivers (sb.o, ad1816.o awe_wave.o) do now support automatically | |
| detecting and configuring isapnp devices. | |
| If you have a not yet supported isapnp soundcard, mail me the content | |
| of '/proc/isapnp' on your system and some information about your card | |
| and its driver(s) so I can try to get isapnp working for it. | |
| === soundcard resources on kernel commandline | |
| Before Linux 2.4 you had to specify the resources for sounddrivers | |
| statically linked into the kernel at compile time | |
| (in make config/menuconfig/xconfig). In Linux 2.4 the resources are | |
| now 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 gone | |
| In 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 gone | |
| In older Linux versions those files exported some information about the | |
| OSS/Free configuration to userspace. In Linux 2.3 they were removed because | |
| they did not support the growing number of pci soundcards and there were | |
| some general problems with this interface. | |
