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

Playback works fine too, with the same syslog entries as 1.0.12
alsa-driver-1.0.14rc1 (alsa-info.sh at http://pastebin.ca/453991 ) modprobe: ALSA hda_intel.c:696: codec_mask = 0x9 ALSA hda_codec.c:1768: hda_codec: model 'toshiba' is selected for config 1179:ff10 (Toshiba) Capture works (output similar to 1.0.12) Playback does NOT work this time: syslog shows a call to azx_pcm_prepare: and 4 calls to hda_codec_setup_stream with different nids (3, 6 ,5, 4 as pointed out my previous post)
alsa-driver-1.0.14rc2 (alsa-info.sh at http://pastebin.ca/453799 ) modprobe: the codec is correctly detected ALSA hda_intel.c:696: codec_mask = 0x9 ALSA hda_codec.c:1764: hda_codec: model 'toshiba' is selected for config 1179:ff10 (Toshiba) Capture works. Playback does NOT work, same syslog entries as 1.0.14rc1 with multiple calls to hda_codec_setup_stream
alsa-driver-1.0.14rc3 (alsa-info.sh at http://pastebin.ca/453785 ) modprobe: the codec isnt detected. 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 ...
