Am trying this - no success.

I plugged the macbook air to the USB input (top input on the digital input card) and am able to see the 818 (shows as "800 Series audio"). I select it and start playing - but sound only comes from Macbook internal speakers.

Any help would be appreciated since this would solve all my issues.

Current set-up for all of the above is Macbook to 818v3 (via USB) and driving DSP8000SE via home run speakerlink. System works fine with other sources, e.g. CD player connected via coax.

Primary system: 818v3, DSP8000 40th SE, Linn Klimax streamer, Esoteric CD

2nd system: DSP7200, 7200HC, 861v8
