After looking through the ALSA configuration and with some googling I think I've discovered the problem. Apparently the default options for ALSA configure the AD1984A Codec (which my card uses) as a 6-jack device, when it's actually a 3-jack.
Appending this line to my /etc/modprobe.d/alsa-base seems to have cleared things up. Thanks!:
Code:
Select alloptions snd-hda-intel model=3stack position_fix=1
For the interested parties, this is straight out of the ALSA configuration documentation:
Code:
Select allModule snd-hda-intel
--------------------
Module for Intel HD Audio (ICH6, ICH6M, ESB2, ICH7, ICH8),
ATI SB450, SB600, RS600,
VIA VT8251/VT8237A,
SIS966, ULI M5461
[Multiple options for each card instance]
model - force the model name
position_fix - Fix DMA pointer (0 = auto, 1 = use LPIB, 2 = POSBUF)
probe_mask - Bitmask to probe codecs (default = -1, meaning all slots)
bdl_pos_adj - Specifies the DMA IRQ timing delay in samples.
Passing -1 will make the driver to choose the appropriate
value based on the controller chip.
[Single (global) options]
single_cmd - Use single immediate commands to communicate with
codecs (for debugging only)
enable_msi - Enable Message Signaled Interrupt (MSI) (default = off)
power_save - Automatic power-saving timtout (in second, 0 =
disable)
power_save_controller - Reset HD-audio controller in power-saving mode
(default = on)
This module supports multiple cards and autoprobe.
Each codec may have a model table for different configurations.
If your machine isn't listed there, the default (usually minimal)
configuration is set up. You can pass "model=<name>" option to
specify a certain model in such a case. There are different
models depending on the codec chip.
