[Alsa-user] File descriptor in bad state

[Silvio L. S. <li...@ie...>]

Hi all
When I try to "cat" a file to /dev/snd/pcmC0D0p, we get the following:

[root@vegeta /root]# cat som>/dev/snd/pcmC0D0p
cat: write error: File descriptor in bad state

If I try to "cat" to /dev/dsp or /dev/audio, then we get:

[root@vegeta /root]# cat som>/dev/dsp
bash: /dev/dsp: No such device
[root@vegeta /root]# ls -l /dev/dsp
lrwxrwxrwx   1 root     root            9 Mar 17 22:14 /dev/dsp ->
/dev/dsp0
[root@vegeta /root]# ls -l /dev/dsp0
crw-rw----   1 root     audio     14,   3 Mar 17 22:14 /dev/dsp0

Well, here is what I have done:
1) downloaded 3 rpm packages: ALSA drivers, utilities and libraries;
   -- the last stable version:

[root@vegeta /root]# cat /proc/asound/version
Advanced Linux Sound Architecture Driver Version 0.5.12a.
Compiled on Mar 17 2002 for kernel 2.2.19-15cl with versioned symbols.

2) ./configure, make & make install each one of the three
3) run the ./snddevices of the driver directory
4) modprobe snd-card-via686a
   (My card is an on-board chip AC97 of VIA 686a Southbridge;
    my motherboard is Soyo K7VTA-Pro, just in case...)

Let's take a look at lsmod:

[root@vegeta /root]# lsmod

That's all. I cannot hear any sound; all we get are
message errors. Maybe I forgot some steps;
Would anyone please help me?

Thanks in advance
