After I compiled all the necessary components
for sound support for my sound card, I have happy
to say linux detects my sound card...but there is
one problem I am as of yet unable to use the card..
since the necessary devices in /dev were never made...

In newere kernel releases the file
/usr/src/linux/drivers/sound/Readme.linux which contained a
script at the end of file which created the dev files
is no longer present.  Could someone tell me where this
file is now located?  Or where I can find a script to
create the dev files?

Log in as root, and:

cd /dev
./MAKEDEV audio

This should create all of the stuff you need.  :-)

(This command may be distribution-dependent, YMMV)

Good luck,

1. What is the difference between /dev/sg0, /dev/scd0 /dev/hdd and /dev/cdrom ?

Hi people.

I'm trying to debug a problem that I'm having with my CDROM player and
cdparanoia.  They crash talking to each other.

What is the difference between accessing the cdrom via /dev/sg0,
/dev/scd0, /dev/cdrom and /dev/hdd ?

/dev/cdrom is a link, right ?  It is a hard or soft link ?  How would I
point it to something else ?

cdparanoia needs to access the CDROM via a scsi interface.  In order for
that to work, one needs to turn OFF ATAPI CDROM support in the kernel and
turn on general scsi and CDROM scsi support.

Right now my /dev/cdrom device points to /dev/scd0.  Given that cdparanoia
needs a scsi interface, shouldn't this point to /dev/sg0 ?

Furthermore, grub load the following: hdd=ide-scsi.  That means that the
IDE ATAPI CDROM drive will be accessed using the scsi interface, right ?
Could I not point /dev/cdrom to /dev/hdd ?
