Very Computer

Hello,
   I have posted question asking about the setting of X windows with my
SiS630 based notebook. Now I am tackling with the sound card.

   Following the instruction at
http://www.in.tum.de/~clemens/ipc-topnote-h.html, I have made the X
worked. But I also followed the instruction on setting up sound and failed.

   If I compile the "(Trident) SiS 7018 PCI Audio" into the kernel
(2.2.18, Red Hat 7), then the booting will report that Trident is found
but it can't allocate irq 0. How could I specify the irq when the sound
support is compiled into kernel? I tired to specify it as "options
trident irq=11 io=0x310" in /etc/modules.conf, but it doesn't work.

   If I make the "(Trident) SiS 7018 PCI Audio" support as module, then
itwon't be loaded automatically, even adding the line |alias
char-major-14 trident" to /etc/modules.conf.  And "modprobe trident"
will load it as unused, where /dev/dsp and /dev/sndstat still can't be "cat"

   Thanks for your attention!

   Yours,
   Raymond

Hello,
   I suspect that my notebook failed to allocate the irq 0 for the sound
card because both the sound card and network card, (which are both part
of the sis630 chipset) conflict on irq 11.

   I looked up in the bios and could not found a place to
re-arrange/assign the irq allocation. How could I resolve the irq conflict?

   I hard coded the module drivers/sound/trident.c, changed all
card->irq to decimal 11. Now, I got my trident load into kernel (not
module), but now the notebook sounds like motor-cycle (beep repeatedly),
just like what the "Documentation"' troubleshooting part say. The
troubleshooting part says this is due to irq-conflict. But I unloaded
the network card (sis900), and the motor-cycle sound continue.

   By the way, the irq readings are found by booting Windows 2000.

   Yours,
   Raymond
