I've got a laptop with an SiS 7012 sound chipset. I've not been able to get sound working with alsa or the regular sound modul support. In essense the driver can't seem to attach the IRQ correctly for the chipset, and so doesn't load. from /var/log/messages Sep 26 15:22:37 lump kernel: PCI: No IRQ known for interrupt pin C of device 00:02.7. Sep 26 15:22:37 lump kernel: ALSA ../alsa-kernel/pci/intel8x0.c:1344: unable to grab IRQ 0 I've been able to get everything to install and run (except the actual driver.) Most of the snd* modules load okay. The /proc/asound files exist, and most of the /dev files for sound are there. I'm running Debian testing distrbution, and have used the make-kpkg tool to do the install of the modules built from the 0.9rc3 Debian-ised source. I can't use the BIOS to reset the IRQ. The error about "pin C" crops up at boot time, and a few other places as well, I have a feeling it might be clashing with the WinModem, which although I've disabled in the BIOS still seems to be in the list of devices with lspci. I've tried a kernel with and without PnP support, with and without ISA variations. I have updated the BIOS, and tried to use WindowsXP to tweak the IRQ settings, all to no avail. WindowsXP reports the sound device, 0,2,7 (as here) as using IRQ 10. There's no module options I can see to set the irq and io when the module loads. Any suggestions? This is really driving me nuts. |

I'm using 2.4.19 at the moment. Are you suggesting a 2.4.20-pre8, or maybe the 2.4.20-pre7-ac or a 2.5.38?
