Sound devices in /dev/

Sound devices in /dev/

[Craig Wright]

Hi, 

I just got a soundblaster 16 pci and after some trouble got it working a 
little bit.  I can play CD's with workman and the sound comes out of the
card.  That's good :), but I'm missing /dev/audio and /dev/sndstat and any
other sound device that I may need.  (I don't know what the others may
be, /dev/dsp?)  Anyway I've run /dev/MAKEDEV and nothing new is created.
I'm at a hurdle I can't jump by myself.  Can anyone help me?  I've tried
using mknod myself, but don't know why they mean by minor and major device
numbers mean.  

Here is the output from the kernel on bootup:

es1371: version v0.19 time 00:44:39 May  1 2000
es1371: found adapter at io 0xe000 irq 5
es1371: features: joystick 0x200
es1371: codec vendor CRY revision 19
es1371: codec features Headphone out 20bit DAC 18bit ADC
es1371: stereo enhancement: Crystal Semiconductor 3D Stereo Enhancement

and here is the output from lspci.  


00:00.0 Host bridge: Acer Laboratories Inc. [ALi] M1541 (rev 04)
00:01.0 PCI bridge: Acer Laboratories Inc. [ALi] M5243 (rev 04)
00:02.0 USB Controller: Acer Laboratories Inc. [ALi] M5237 USB (rev 03)

00:0f.0 IDE interface: Acer Laboratories Inc. [ALi] M5229 IDE (rev c1)


I think this is all relevant, but I don't know for sure.  Can anyone help?

Thanks in advance,

i would have thought that sndconfig would have made those
devices, but maybe it just instals  the driver.

did you run it?

They aren't used with this driver (es1371), it's pci and therefore a
very different beast.

See the docs in /usr/src/linux/Documentation/sound/*

For the pci sound cards, use /proc and other such tools to get the
info you need.

Cool, it's not a bad card (got one myself here).  The 3D stuff is
awesome with windows games that know about it, and the switches are
there for linux to use it too.  (Although I must admit that I've never
tried the 3D sound for linux - anyone got a program or sound file that
will "show it off" ?)

I'm no sound driver guru, so perhaps someone else might want to make
things a lot clearer than I have.  AFAIK, /dev/sndstat and co. are
obselete and don't work for pci-based sound cards, they only have
relevance for the older isa sound cards.
