PCI wierdness
Hi,
I've been trying to install a sound driver for my YMF744 based sound card. I'm using
ALSA with a custom 2.4.3 kernel. I got it to work for 2 seconds about 5 days ago
before my box crashed. After that my box refuses to acknowledge the existence
of IRQ5.
Sound support has been installed either as built-in or as a module. PCI support was either <BIOS> or <ANY>. I also tried "ymfpci" built-in or as a module.
What is weird is that:
1) lspci
00:0f.0 Multimedia audio controller: Yamaha Corporation YMF-744B [DS-1S Audio Controller] (rev 02)
2) cat /proc/pci
Bus 0, device 15, function 0:
Multimedia audio controller: Yamaha Corporation YMF-744B [DS-1S Audio Controller] (rev 2).
IRQ 5.
Master Capable. Latency=32. Min Gnt=5.Max Lat=25.
Non-prefetchable 32 bit memory at 0xdf000000 [0xdf007fff].
I/O at 0xd000 [0xd03f].
I/O at 0xd400 [0xd403].
3) modprobe snd-ymfpci - does not produce any errors
4) lsmod

Did I forget to restart or reprobe or reinitialize something?
Thanks for any info,
