I recently purchased a new motherboard, and have been running into a
problem with my older soundcard.
Before i get started, here's some info about my computer:
Tyan s1837DLUN-BX Thunderbolt 100 (Onboard Ethernet, Dual Onboard
Scsi,Dual Proc's)
AWE64 Gold sndcard IO=220 irq=5 dma=1 dma16=5
Running redhat linux 6.1 and kernel 2.2.13.
Up until i put in my new motherboard, i had been using the oss sound
modules for 100% soundblaster compatible w/ no problems.
After i installed my new motherboard, and turned OFF 'PnP Aware OS' in
my bios, i tried booting my old kernel and got this error:
Dec 14 19:32:00 irc kernel: sb: Interrupt test on IRQ5 failed - Probable
IRQ conflict
Dec 14 19:32:00 irc kernel: <Sound Blaster 16 (4.16)> at 0x220 irq 5 dma
1,5
So i boot to windows, and it detect's my soundcard on the settings i
specified in the kernel, with _no_ conflicts.
I recompiled 2.2.13 w/ modular sound and tried:
modprobe sound
insmod uart401
insmod sb io=0x220 irq=5 dma=1 dma16=5
and got the same "Probable IRQ Conflict"
So i recompiled the kernel w/o any sound, and downloaded OSS from
www.opensound.com
It autodetected my soundcard fine, on the settings i thought it would,
and upon running 'soundon' my card worked properly.
So at this point i was reasonably certain there was no problem with the
settings i was giving it.
I even went so far as to force the single ISA slot i have on my
motherboard to use irq 5, dma 1 and 5 from the bios, to no avail.
Here is the output of my cat'ing /proc/interrupts and /dev/sndstat
*while using external OSS*

Note: When compiling my kernel with sound, i selected:
CONFIG_SOUND_OSS=y
CONFIG_SOUND_DMAP=y
CONFIG_SOUND_SB=y
CONFIG_SB_BASE=220
CONFIG_SB_IRQ=5
CONFIG_SB_DMA=1
CONFIG_SB_DMA2=5
CONFIG_SB_MPU_BASE=330
CONFIG_SB_MPU_IRQ=-1
I did not select other low level sound drivers, and i tried the kernel
both with and with out PnP built into the kernel.
I had read on a webpage about perhaps putting #define SB_NO_IRQ_TEST in
/usr/src/linux/drivers/sound/sb_common.c in the headers,
but i tried it with no results.
Any help you could give me would be very helpful, as i had previously
had great luck with in kernel sound, and would like to continue to do so
as i often run development kernels, which OSS is not released for
seperately :(
If anyone replies to this, please cc: it to me incase i miss the post to
the mailing list,
If any more information is needed please feel free to mail me.
thanks in advance,
