hi. i recently upgraded my old computer to a nice new Intel D845GEBV2
motherboard, with everything integrated. turns out this wasn't such a
good idea because the linux driver for the video section is very buggy,
so i ended up buying a video card. no great worries.
my problem now is the sound: i get no sound out of the system.
if i try to control sound (e.g. with the gnome-volume-control) i get:
I was not able to open your audio device.
Please check that you have permissions to open /dev/mixer
and make sure that you have sound support compiled into your
kernel
here are my mixer permissions:
$ ls -l /dev/mixer
crw-rw-rw- 1 michael root 14, 0 Aug 30 16:31 /dev/mixer
now these were originally 600, but no difference after i changed them.
i also see in my kernel messages:
Feb 10 17:20:19 dhcppc4 insmod:
/lib/modules/2.4.18-14/kernel/drivers/sound/i810_audio.o: init_module: No such device
Feb 10 17:20:19 dhcppc4 insmod: Hint: insmod errors can be caused by incorrect module
parameters, including invalid IO or IRQ parameters. You may find more
information in syslog or the output from dmesg
Feb 10 17:20:19 dhcppc4 insmod:
/lib/modules/2.4.18-14/kernel/drivers/sound/i810_audio.o: insmod sound-slot-0 failed
Feb 10 17:20:19 dhcppc4 kernel: i810_audio: Codec not ready.. wait.. no response.
Feb 10 17:20:19 dhcppc4 kernel: i810_audio: Audio Controller supports 6 channels.
Feb 10 17:20:19 dhcppc4 kernel: i810_audio: Defaulting to base 2 channel mode.
Feb 10 17:20:19 dhcppc4 kernel: i810_audio: Primary codec not ready.
Feb 10 17:20:19 dhcppc4 modprobe: modprobe: Can't locate module sound-service-0-3
(i think that since the 845 chipset is built on the 810 chipset, many of the drivers
are for the 810 chipset.) so i checked out my modules:
# ls -l /lib/modules/2.4.18-14/kernel/drivers/sound/i810_audio.o
-rw-r--r-- 1 root root 30572 Sep 4 10:47
/lib/modules/2.4.18-14/kernel/drivers/sound/i810_audio.o
although sound-slot-0 is missing, but that's the second message, so i'm not sure if
that's
the main problem.
and
# cat /etc/modules.conf
alias parport_lowlevel parport_pc
alias eth0 eepro100
alias usb-controller ehci-hcd
alias sound-slot-0 i810_audio
post-install sound-slot-0 /bin/aumix-minimal -f /etc/.aumixrc -L >/dev/null
2>&1 || :
pre-remove sound-slot-0 /bin/aumix-minimal -f /etc/.aumixrc -S >/dev/null 2>&1
|| :
alias usb-controller1 usb-uhci
and dmesg says:
Intel 810 + AC97 Audio, version 0.22, 13:45:06 Sep 4 2002
PCI: Found IRQ 3 for device 00:1f.5
PCI: Sharing IRQ 3 with 00:1f.3

i810_audio: Audio Controller supports 6 channels.
i810_audio: Defaulting to base 2 channel mode.

i'm not quite sure what next to try - any suggestions?
thanks,
michael
