=== 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.
