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.
- On the "Monitor Inputs" and "Monitor PCMs" tabs, set all monitor inputs and monitor PCMs to around 20.
- On the "Patchbay / Router" tab, set all to PCM out.
- 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!
