Hi all,
First of all, I'm deaf, so I have no experience or much idea about
sound in any situation - let alone setting it up under Linux. I just
had to reinstall Debian Etch on one of my frontends which is running
an AMD Athlon 800MHz processor on a SiS motherboard with integrated
stuff, and a Geforce MX 4000 video card.
My main problem is that my girlfriend is hearing and requires sound,
also when playing a DVD via MythTV, I get spews of "Error opening
audio device (dev/dsp), the error was: No such file or directory"
making the DVD video jerk badly rendering it unwatchable.
Viewing the list of modules and dmesg seems to show the sound device
was recognised and loaded. Here's a dmesg snippet:
input: PC Speaker as /class/input/input1
ACPI: PCI Interrupt Link [LNKB] enabled at IRQ 10
PCI: setting IRQ 10 as level-triggered
ACPI: PCI Interrupt 0000:00:01.4[B] -> Link [LNKB] -> GSI 10 (level,
low) -> IRQ 10

also the output from lsmod....

I've tried various stuff including "mknod /dev/dsp c 14 3" but that
just changes "No such file or directory" to "Permission denied" and
that gets deleted at the next reboot.
Am I missing some kernel module or binary package? Probably
something simple and obvious....
Thanks very much for your time in advance!
