I've got an IKMultimedia IRig Pro Connected to PI4B It appears in Jack under ALSA-MIDI but I can't find the System-Audio Input

Running lsusb shows me

Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 005: ID 093a:2510 Pixart Imaging, Inc. Optical Mouse

dmesg says

cat /proc/asound/cards says

 0 [ALSA           ]: bcm2835_alsa - bcm2835 ALSA
                      bcm2835 ALSA

                      IK Multimedia iRig PRO at usb-0000:01:00.0-1.1, full speed 

When I press the right mouse button on the volume button at the taskbar, I can Use iRig Pro as an output device but opening the volume settings there are no tabs for input devices, maybe because there are no input devices?

I tried adding dwc_otg.speed=1 to my /boot/cmdline.txt file as this should help on usb 1.1 DAC issues but no luck.

alsa-base.conf is empty at the moment

running alsamixer lets me select iRig Pro as Soundcard with F6 but it just says this device has no controls.

Any Idea to get this working?

  • Are you sure the device connected is supported by Raspberry Pi 4? cgi.ikmultimedia.com/ikforum/…

  • Not really - it was just the only usb audio device I got at my place right now so I was giving it a try.

  • I'm sure it's supported for rpi3 but not sure about rpi4. If you have another rpi rather than rpi4, evaluate your procedures. Hope you find the solution.

  • Sadly its my first and only Pi anyway will try to find a solution
