Hi,
Just some info for Slackware-8.0 users that I have discovered.
For those who install the kernel 2.4.5 image and source, please note that
the kernel is compile with "/dev file system support" enable under "File
systems".
This create a problem when compiling alsa driver. Alsa config will assuming
that devfs will be automatically mounted at boot. So after compiling and
install the alsa drivers, when you do a modprobe, the alsa driver will tries
to create the "/dev" directory under devfs (Under normal case, "/dev" should
be at /proc/asound). So without this "/dev" directory, even though you see
the driver loaded correctly, there will no sound and all alsa utilities
throw out error like "mixer not found" blah blah blah.
Solutions: Before compiling alsa drivers, do either
1) With kernel 2.4.5 and higher source,
- do "make menuconfig".
- Unselect "/dev file system support" under file system.
- Save and exit
- do "make dep"
(Recompile of kernel not necessary)
Or
2) Recompile kernel with "/dev file system support" AND "Automatically mount
at boot" enable.
(Note: Slackware-8.0 have already prepared /etc/rc.S to mount devfs
whenever necessary)
Hope this info is of help.
Cheers,
Wayne
