In a terminal as a user:

Code: Select all

aplay -l

Use 'a2j -e' instead of 'a2jmidid -e'.
The 1st option enables dbus.

Thank you.

1. "aplay -l"
Before, I use it as a music player, and not to know how it work as a driver...?
Can you show it...?

2. "Use 'a2j -e' instead of 'a2jmidid -e'"
My midi controller is USB type. Can "a2j" support on both "midi" / "USB" port type...?

Or don't use a2j at all. I don't.

Do you use Jackaudio on Linux? I think that's needed to use the Focusrite.

    @Alsa2jack (MIDI):
    install:
    ...
You only need "a2j -e" (jack2) or "a2jmidid -e" (jack1) if you want to use ALSA and jack (MIDI) at the same time.
If you don't care if one part is listed on ALSA, the other on Jack (MIDI) - and of course you can't connect them - you don't need "a2j -e" (jack2) or "a2jmidid -e" (jack1).

That's weird. Are you sure the Focusrite is on?

1. It is find that both recording and play back are normal

Testing with Ardour, what is the setting under Audio/midi setup..?

1. Audio System
2. Driver
3. Midi System

What command produces the output above?

Kelvin wrote:the driver can not be load

The driver for an external USB audio device is called snd_usb_audio and I'll bet you a million dollars that it actually is loaded. What we call a "driver" in Windows world, we call a "kernel module" in Linux world. List kernel modules with the command lsmod like so:

Code: Select all

lsmod | grep usb_audio

Output should look something like this:

Code: Select all

lsmod | grep usb_audio
snd_usb_audio         155107  0
