any help would be immensely appreciated. or if someone would just say this doesn't
work, that too would put me out of my misery.
status with alsa
- alsa-driver-0.9.0rc8b
- alsa-lib-0.9.0rc8c
- alsa-utils-0.9.0rc8a
i run redhat 8.0 and i use gnome.
The good:
my sound is good. i can hear sound from the line in, mic, my cd player, realplayer.
The problems:
1. the warnings about vmalloc_to_page during driver build
2. aplay and arecord do not work. they return
aplay: pcm_write:1024: write error: Input/output error
arecord: pcm_read:1105: read error: Input/output error
3. mpg123 plays and repeats the same 1/2 second long after the job is killed
4. line in cannot be set to capture
5. no error messages in dmesg or /var/log/messgaes
Background information
1. contents of .asoundrc
pcm.via82xx {
type hw
card 0
}
ctl.via82xx {
type hw
card 0
}
2. /sbin/modinfo soundcore
filename: /lib/modules/2.4.18-14/kernel/drivers/sound/soundcore.o
description: "Core sound module"

3. How i installed the driver, libs, and utils
PATH=$PATH:/sbin
cd /usr/src/alsa/alsa-driver-0.9.0rc8b
./configure --with-cards=via82xx --with-sequencer=yes
# configure looks good, no errors
make

4. inserting the modules into the kernel occurred without a problem.
i took out the references to sound in modules.conf before i booted
modprobe snd-via82xx
modprobe snd-pcm-oss
modprobe snd-mixer-oss
modprobe snd-seq-oss
before (during previous installations of alsa) i would use the script
cat /proc/modules|gawk '/^snd-/{print $1}'|xargs -i rmmod {}
and when i inserted the modules it would complain about unresolved modules

11. the documentation in
http://www.alsa-project.org/~valentyn/Alsa-sound-mini-HOWTO-6.html
says that...
You can find installed cards in /proc/asound/cards, then find
information about card0 in /proc/asound/0, /proc/asound/1 for card1
etcetera.
If cat /proc/asound/card1/pcm0 shows something like
ES1370 DAC2/ADC
Playback isn't active.
Record isn't active.
but i don't have a /proc/asound/card0/pcm0. i have
/proc/asound/card0/pcm0* where * is c or p
