Sorry about the duplicate and cross post, but I am really stuck and have had no responses. The probe of my sound device on my laptop doesn't work -- it picks up the wrong device (the USB bus controller). Can anyone point me in the right direction, at least? I don't mind reading through source code, but I don't know where to start... Thanks! ----- Original Message ----- From: Peter Kurpis To: [email protected] Sent: Thursday, April 08, 2004 10:20 PM Subject: problems reconfiguring kernel for sound I have a strange problem installing 4.7 on my Toshiba 1135 laptop. (I need 4.7 for compatibility reasons.) To add support for my Avance AC97 audio hardware, I added the following lines: device pcm device sbc0 at isa? irq 17 port 0x18C0 flags 0 options PNPBIOS (and tried various other permutations). The irq and port are from Windows, flags is 0 because there is apparently no DMA. When I reboot, it seems that my USB controller has taken over /dev/pcm ! dmesg | pcm pcm0: <Intel 82801DB (ICH4)> port 0x18c0-0x18ff,0x1c00-0x1cff mem 0xe0100800-0xe01008ff,0xe0100c00-0xe0100dff irq 10 at device 31.5 on pci0 Note that the IO port and memory addresses are right, but the IRQ is wrong (should be 17). I don't know what device 31.5 is, and don't know how to look it up. ? After cd /dev; sh MAKEDEV snd0 , if I try cat someAudioFile.au > /dev/audio, it prints gibberish on the screen, and I can't recover control. What's even weirder is that when I comment out all the USB support lines (as well as the smbus, ichsmb, and smb device lines I added for the 82801) in the configuration file, and rebuild the kernel, the devices uhci0 through uhci2 and usb0 through usb2 *still* show up on bootup (and in dmesg)! Can anyone help with ideas of what could be wrong, or where to start troubleshooting?
