			Make sure that you're sending the appropriate playback channels to the appropriate speakers -- see the "Monitor PCM" tab to control this. Typically, you'll want to un-gang the channels you want to include (otherwise you get center/mono for those channels). When Audacity's output is set to go to the M-Audio (rather than somewhere else), it apparently sends the two mix output channels to PCM Out 1 and PCM Out 2 -- so ungang these and set PCM Out 1 to left-high / right-low (so the left mix channel will go to the left stereo channel) and PCM Out 2 the opposite (so the right mix channel will go to the right stereo channel).

			I ''think'' this makes sense, but I should probably draw a diagram at some point.

	It's not clear how these are derived, since the D66 does not have mic or CD inputs; all are line level. In any case, it doesn't seem to matter which D66 input you pick; you always get the same signal, which seems to be HW IN 1.

This is about trying to use the [[M-Audio Delta 66]] multitrack audio ADAC in Linux. This apparently uses the [[Envy24]] chipset, for which there are drivers.

As of 2017, the Envy24 drivers are part of the standard distro and seem to work pretty well. There are two different control panels (approximately replicating the functionality of the one provided by M-Audio for Windows); "Mudita24" did not seem to work right, but "Envy24 Control Utility" (E24CU for short) more or less does -- as far as I can tell what it is ''supposed'' to be doing, anyway.
