Estuve haciendo algunas pruebas para guardar sesiones de audio y conexiones con Ladish y Jack Session. Durante el proceso, Ladish no reconoció mi interfase de audio M-Audio Fast Track Ultra (FTU); la cual ya funcionaba bien con QjackCtl anteriormente.
Al querer volver a iniciar QjackCtl por su cuenta y seleccionar mi FTU resulta que el programa no muestra las entradas y salidas correctas; si no que lanza los canales de la tarjeta del portátil (a veces mezclados con las entradas y salidas de Pulse Audio). Ya reinicié Jack, el equipo y la interfase y no funciona. También probé borrar al configuración de Jack de la FTU y volverla a realizar, pero sucede lo mismo.
Lo interesante es que sí aparece en la lista de dispositivos, y está bien reconocida por ALSA...
Aquí mi salida de cat /proc/asound/cards:

En ambos casos las entradas y salidas se muestran igual: dos entradas y cuatro salidas (bocinas y audífonos)... Mi FTU tiene teóricamente ocho entradas y ocho salidas (o eso detectaba jack anteriormente).
Estoy corriendo Ubuntu+KXStudio con el Kernel de baja latencia. Anteriormente mi FTU funcionaba bien con sus entradas y salidas; para configurarla lo que había hecho era cambiar los dispositivos de entrada y salida a Fast Track Ultra hw:1. Todo lo demás lo dejaba tal y como venía.
Espero me puedan ayudar. Gracias.
