Hallo,
I cross-compiled alsa-lib-1.2.2 and alsa-utils-1.2.2 for LibreELEC on a Raspberry Pi after adding MIDI support to the kernel (4.19.36). When I connect my Clavinova digital piano (which comes with an embedded USB MIDI interface) to the Raspberry, it does not get listed as a valid I/O by arecordmidi/aplaymidi. It is, however, recognized by amidi as a raw device; amidi --dump -p hw:1,0,0 does indeed list events from the keyboard. Some misc debug information: dmesg: [606964.257417] usb 1-1.2: new full-speed USB device number 7 using dwc_otg [606964.395178] usb 1-1.2: New USB device found, idVendor=0499, idProduct=1034, bcdDevice= 1.00 [606964.395207] usb 1-1.2: New USB device strings: Mfr=1, Product=2, SerialNumber=0 [606964.395223] usb 1-1.2: Product: Clavinova [606964.395240] usb 1-1.2: Manufacturer: YAMAHA Corporation kodi:~ # ./aplaymidi -l Port Client name Port name 14:0 Midi Through Midi Through Port-0 kodi:~ # ./aseqdump -l Port Client name Port name 0:0 System Timer 0:1 System Announce 14:0 Midi Through Midi Through Port-0 kodi:~ # ./amidi -l Dir Device Name IO hw:1,0,0 Clavinova MIDI 1 kodi:~ # lsmod | grep snd snd_hrtimer 16384 0 snd_seq_midi 16384 0 snd_seq_midi_event 16384 1 snd_seq_midi snd_seq_dummy 16384 0 snd_seq 57344 3 snd_seq_midi_event,snd_seq_dummy,snd_seq_midi snd_seq_device 16384 2 snd_seq,snd_seq_midi snd_usb_audio 163840 0 snd_usbmidi_lib 28672 1 snd_usb_audio snd_hwdep 16384 1 snd_usb_audio snd_pcm 77824 1 snd_usb_audio snd_timer 28672 3 snd_seq,snd_hrtimer,snd_pcm snd_rawmidi 28672 2 snd_seq_midi,snd_usbmidi_lib snd 53248 8 snd_hwdep,snd_seq,snd_usb_audio,snd_timer,snd_rawmidi,snd_usbmidi_lib,snd_seq_device,snd_pcm Thanks in advance, David _______________________________________________ Alsa-user mailing list Alsa-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/alsa-user
