Stan,
Thanks, yes I saw that and wondered the same thing. In fact his problem is a
little different - in his dmesg log, he gets:
1. [ 42.872651] ACPI: PCI Interrupt 0000:00:1b.0[A] -> GSI 22 (level,
low) -> IRQ 21
2. [ 42.872657] PCI: Unable to reserve mem region #1:[EMAIL PROTECTED] for
device 0000:00:1b.0
3. [ 42.872661] ACPI: PCI interrupt for device 0000:00:1b.0 disabled
4. [ 42.872668] HDA Intel: probe of 0000:00:1b.0 failed with error -16
compared to mine:
1. [ 40.254047] ALSA
/build/buildd/linux-ubuntu-modules-2.6.24-2.6.24/debian/build/build-server/sound/alsa-driver/pci/hda/../../alsa-kernel/pci/hda/hda_intel.c:1892:hda-intel:
no codecs found!
2. [ 40.254089] ACPI: PCI interrupt for device 0000:00:1b.0 disabled
So in his case there's what looks like a conflict, rather than in mine, just
the codec is not detected. The end result is the same.
I did try installing a fresh 7.10 and 7.04 Ubuntu and now I'm beginning to
doubt my recollection that the sound ever worked - it didn't on either of
those installs....
Peter
