I'm using the R16 as MIDI controller [R16 -> a2jmidid (alsa midi)-> (jack midi) ardour3] and audio capture [R16 -> alsa_in (alsa device with 8 input channels) -> ffado jack host]. It seems to work quite well when is running, but there is something not fine: - it takes a long time to the device to appears as an alsa device since it is detected from the kernel module - at least when it is not used (but I think it can occurs even when streaming) it seems to block ALSA for moments. Meanwhile alsa seems is unresponsive. Trying to start qjackctl (just open the frontend, not even starting jack) opened an unresponsive widget. As soon I disconnected the USB from the R16, the buttons and the control of the widget appeared. - I was with the above described chain (jack + R16 alsa_in) , and all the audio devices suddenly hanged. I saw in the R16 the sample rate at 96kHz (when it was -as JACK- at 48kHz) A dmesg shows this : > [ 268.877864] 3:1:1: cannot get freq at ep 0x3 > [ 272.489903] firewire_core 0000:07:00.0: created device fw1: GUID > 00130e0100060dce, S400 > [ 273.879240] 3:1:1: cannot set freq 44100 to ep 0x3 > [ 278.903419] 3:1:1: cannot get freq at ep 0x3 > [ 283.904662] 3:1:1: cannot set freq 44100 to ep 0x3 > [ 286.633916] 3:1:1: cannot get freq at ep 0x3 > [ 286.638154] 3:1:1: cannot set freq 44100 to ep 0x3 > [ 286.671291] 3:1:1: usb_set_interface failed (-71) > [ 286.675542] 3:1:1: usb_set_interface failed (-71) > [ 286.679792] 3:1:1: usb_set_interface failed (-71) > "" * 20 > [ 286.799821] 3:1:1: usb_set_interface failed (-71) > [ 286.830497] usb 1-1.4: USB disconnect, device number 3 > [ 304.980599] hda-intel: IRQ timing workaround is activated for card > #0.
