Installing ALSA ... (continued.)

[Adam Bogacki <afb@paradise.net.nz>]

Thanks, I've printed and read the

Tux:/usr/share/doc/HOWTO/en-txt#vi Alsa-sound

document, and read the <www.alsa-project.org> stuff and when I follow 
their advice
the modules compile but the process keeps breaking down at a certain point.

The good news is that I think I understand more about what is going on 
and the
breakdown is further along the track - I realised [depmod -ae] the 
"unresolved symbols" all had to do with pcmcia so I apt-installed that 
.deb and that problem ceased.

'dmesg' tells me I have the es1371 card and 'alsa-project.org' tells me 
I need the
snd-ens13711 module.

I apt-installed kernel-image-2.4.25-1-686 and alsa-modules-2.4.25-1-686 
(& kernel-headers).

> Tux:~# modinfo soundcore
> filename:    /lib/modules/2.4.25-1-686/kernel/drivers/sound/soundcore.o
> description: "Core sound module"
> author:      "Alan Cox"
> license:     "GPL"

... so I don't need to recompile the kernel.


I bunzipped2 & untarred alsa-modules and then

> Tux:/usr/src/modules/alsa-driver# ./configure --with-cards=ens1371 
> --with-sequencer=yes;make;make install

which went through a long checking routine without error but then ...

and more of the same.

When I try

Trying to do this the easy way, I tried alsaconf, but it did not 
recognise my soundcard.

What is 'SNDRV_DMA_TYPE_***'  and how do I fix this ?

It's after midnight ... zzzzzz
