The M-Audio Delta series cards are based on the VIA Ice1712 audio chipset. Cards using this chip require that you install the alsa-tools package, because it contains the envy24control program. Envy24control is a hardware level mixer/controller. You can use alsa-mixer but you will save yourself some hassle not to try it. Note that this section has no information on MIDI setup or usage.

Open the mixer application:

$ envy24control

This application can be more than a bit confusing; see envy24control for guidance on its use. That said, here is a very simple working setup for multitracking with Ardour.

  1. On the "Monitor Inputs" and "Monitor PCMs" tabs, set all monitor inputs and monitor PCMs to around 20.
  2. On the "Patchbay / Router" tab, set all to PCM out.
  3. On the "Hardware Settings" tab, verify that the Master Clock setting matches what is set in Qjackctl. If these do not match you will have xruns out of control!
