Well, yeah I know that - but the kernel also provides *drivers* for a
whole host of other devices as well, which may (like ALSA) need
additional tools to actually make use of that hardware (e.g.
What I was trying to convey is we don't deal with configuring sound
support explicitly in LFS, it is quite rightly a BLFS issue.
Additionally, I wonder why OSS compatibility is such a big problem? As
2.6.x kernels have support for ALSA, and it is now officially considered
*the* supported sound provider (at least to my limited knowledge),
requiring OSS compatibility is a bug for upstream audio-related package
maintainers to be made aware of IMO! Anyway, this is fast going way
OT and encroaching on BLFS territory, so I'll stop now :)

As am I, I think. Talking of woeful documentation...:) Is any of this
(the modules script and /etc/modprobe.conf stuff) in the book yet? I
took a quick look and couldn't see anything immediately. I'm wondering
how we can provide decent hints as to what is required, without going
into too much detail. Can those types of devices/modules that aren't
supported by udev & hotplug natively be grouped together in some way (I
keep on thing of them as psuedo-devices and auxilliary modules, but I'm
not sure this is either the correct terminology or even accurate)?
