It should have had > a line similar to "Subsystem: Unknown device 1631:c017". I've verified that lspci doesn't show any subsystems for the HDA device. It does show (known) subsystems for other devices (USB, SATA, IDE, etc.). Kernel messages are from 1.0.13 with --with-debug=full: "modprobe snd-hda=intel" [23787.349708] ACPI: PCI Interrupt 0000:00:1b.0[A] -> GSI 23 (level, low) -> IRQ 225 [23787.350397] PCI: Setting latency timer of device 0000:00:1b.0 to 64 Messages from insertion with model=arima|6stack-dig|3stack-dig are identical except for the extra KERN_INFO like: [23873.974754] ALSA /data/downloads/alsa-driver-1.0.13/pci/hda/hda_codec.c:1741: hda_codec: model 'arima' is selected One possible complication is that this system wasn't booted directly from EFI. I have a new enough firmware that I've installed Linux with a legacy MBR-style partition scheme, and use LILO at the MBR to boot. The Apple firmware seems happy enough with this, and perhaps the BIOS it emulates is causing problems (or maybe not). Linux is the only OS on this machine. > For grins, try "model=arima". This should toggle the eapd control bit. I've tried that model, and I see differences in the mixer but I don't get different sound. What else should I notice? Earlier today with no model arg present, I unmuted and maxed out all the mixer channels, and found that with PCM and Surround channels all the way up, and external amplifier up, I could hear the music I had playing, though it was still very quiet. So at least one channel is finding the line-out jack, quietly. -- Shaw Terwilliger <sterwill@xxxxxxxxxxxxxx> SourceGear LLC
