No sound again. IRQ conflict?!

J_Szucs · 03-09-2004, 11:46 AM

I upgraded my SuSE 7.3 (kernel 2.4.18) to SuSE 9.0 (kernel 2.4.21-99), now I have no sound with the alsa driver.
lspci results:

Code:

00:0a.0 Multimedia audio controller: Ensoniq 5880 AudioPCI (rev 04)
	Subsystem: Ensoniq: Unknown device 8001
	Flags: bus master, slow devsel, latency 32, IRQ 11
	I/O ports at f000 [size=64]
	Capabilities: [dc] Power Management version 2

00:0f.0 IDE interface: ALi Corporation M5229 IDE (rev c2) (prog-if fa)
	Flags: bus master, medium devsel, latency 32, IRQ 10
	I/O ports at f400 [size=16]
	Capabilities: [60] Power Management version 2

01:00.0 VGA compatible controller: nVidia Corporation NV11DDR [GeForce2 MX 100 DDR/200 DDR] (rev b2) (prog-if 00 [VGA])
	Flags: bus master, 66Mhz, medium devsel, latency 248, IRQ 11
	Memory at dc000000 (32-bit, non-prefetchable) [size=16M]
	Memory at d0000000 (32-bit, prefetchable) [size=128M]
	Expansion ROM at <unassigned> [disabled] [size=64K]
	Capabilities: [60] Power Management version 2
	Capabilities: [44] AGP version 2.0

I see that my sound card and vga card use the same IRQ. Is it normal? If not, how to correct it?

Some more notes:
I cannot configure the sound card with yast, as it complains of possible errors, among which hardware conflict is also mentioned.
I CAN manually configure the sound card with alsaconf, and in fact sound begins to work; alsaconf even says saving some changes to /etc/modules.conf, but then sound will not work again after I reboot :-(.
It is also strange that alsaconf should be run automatically during startup (it is enabled in the runlevel editor), yet it can only configure the card if it is run manually.

I checked the SUSE update site, but I could not find any sound or kernel related updates for my distro there.

Is there a workaround to have sound without having to run alsaconf manually?
I myself can run alsaconf OK, but my 5 years old son cannot, so he presently highly prefers Windows over Linux, which is a nonsense.

Any help?

"I see that my sound card and vga card use the same IRQ. Is it normal? If not, how to correct it?"

It is normal to have more than one device stacked on some of the IRQs. But sometimes the IRQ stack is set up incorrectly and has to be fixed with alsaconf.

"alsaconf even says saving some changes to /etc/modules.conf, but then sound will not work again after I reboot :-(."

Check /etc/modules.conf before and after alsaconf makes its changes to make sure that alsaconf really does change something in /etc/modules.conf. If not, you may have ownership or permissions problems with /etc/modules.conf.

If /etc/modules is really being changed then the problem may be the boot alsaconf script changing things back to the wrong way again. If that is the problem then try disabling the boot script that runs alsaconf by commenting it out so that your manual changes become permanent.
