Greetings- The recent Intel ICH6R chipset has 'Intel HD audio' which can play more simultaneous channels than the AC97 spec systems, among other features. This scheme is used on all the newest Intel chipsets supporting the 775 series P-4 processors. Apparently this requires more IO resources as the error below is returned: pcm0: <Intel ICH6 (82801FB/FR/FW/FRW)> mem 0xfebf8000-0xfebfbfff irq 16 at device 27.0 on pci0 pcm0: unable to map IO port space To get the driver to recognize the chip, the device ID was modified: < #define ICH6ID 0x266e8086 /* ICH6 needs to be treated as ICH4 */ --- > #define ICH6ID 0x26688086 /* ICH6 needs to be treated as ICH4 */ 642c642 < Any help getting this working is very greatly appreciated. -kim -- w8hdkim@gmail.com
