I currently have outputs plugged into both ports, but I have yet to get any sound from either one.

On the macmini the linux kernel used to send the output to the line in so plug into that :) cat /proc/asound/card0/codec#* | grep Codec Let's asume that you get STAC9220/9221 /usr/share/doc/kernel-doc-<version>/Documentation/sound/alsa/HD-Audio-Models.txt STAC9220/9221 ============= ref Reference board 3stack D945 3stack 5stack D945 5stack + SPDIF intel-mac-v1 Intel Mac Type 1 intel-mac-v2 Intel Mac Type 2 intel-mac-v3 Intel Mac Type 3 intel-mac-v4 Intel Mac Type 4 intel-mac-v5 Intel Mac Type 5 intel-mac-auto Intel Mac (detect type according to subsystem id) macmini Intel Mac Mini (equivalent with type 3) macbook Intel Mac Book (eq. type 5) macbook-pro-v1 Intel Mac Book Pro 1st generation (eq. type 3) macbook-pro Intel Mac Book Pro 2nd generation (eq. type 3) imac-intel Intel iMac (eq. type 2) imac-intel-20 Intel iMac (newer version) (eq. type 3) ecs202 ECS/PC chips dell-d81 Dell (unknown) dell-d82 Dell (unknown) dell-m81 Dell (unknown) dell-m82 Dell XPS M1210 auto BIOS setup (default) And since this white little box contains the <a href="http://www.smolts.org/reports/view_device/AR242x%20802.11abg%20Wireless%20PCI%20Express%20Adapter">Atheros Communications, Inc.
