Tobin, Unfortunately, ACPI was on at all times. My laptop hardly ever boots without ACPI (randomly, the SATA driver fails before it can even mount the root partition). I ran some more tests today: I loaded Ubuntu Edgy from the live CD where the sound chip used to work (kernel 2.6.17, alsa driver 1.0.12rc1). Obviously the sound works straight away. From there , I ran the same series of test: download and build (--with-debug=detect) the next version of alsa-driver, run a capture from mic and try playing it back, check syslog and run alsa-info.sh. I did this for successive versions of alsa-driver (starting with 1.0.12) until it fails. Here are the results: Alsa driver 1.0.12rc1(shipped with edgy): capture: working, playback working, alsa-info.sh at http://pastebin.ca/453947 Alsa driver 1.0.12: (alsa-info.sh at http://pastebin.ca/453971 ) syslog lines after modprobe: ACPI: PCI Interrupt 0000:00:14.2[A] -> GSI 16 (level, low) -> IRQ 233 ALSA alsa-driver-1.0.12/pci/hda/../../alsa-kernel/pci/hda/hda_intel.c:663: codec_mask = 0x9 hda_codec: Unknown model for ALC861, trying auto-probe from BIOS...

ALSA hda_intel.c:696: codec_mask = 0x9 capture and playback dont work. Summary: I tried alsa-driver 1.012 through to 1.0.14rc3 on ubuntu edgy (kernel 2.6.17). 12 and 13 work fine, 14rc1 and 2 capture works but not playback, 14rc3 doesnt detect the codec. What next ? not sure, maybe make a diff of alsa-kernel/pci/hda-intel between releases 13 and 14 ... _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
