With my previous kernels (2.6.29 and 3.2.29), I tried plugging the Motif XF to my PC via USB, but it wasn't recognized. After my latest system upgrade to Slackware 14.1 and kernel 3.10.17, I decided to try again, to see if something had changed. To my surprise, the MIDI ports were recognized. $ aplaymidi -l Port Client name Port name 14:0 Midi Through Midi Through Port-0 28:0 Virtual Raw MIDI 3-0 VirMIDI 3-0 29:0 Virtual Raw MIDI 3-1 VirMIDI 3-1 30:0 Virtual Raw MIDI 3-2 VirMIDI 3-2 31:0 Virtual Raw MIDI 3-3 VirMIDI 3-3 32:0 YAMAHA MOTIF XF8 YAMAHA MOTIF XF8 MIDI 1 32:1 YAMAHA MOTIF XF8 YAMAHA MOTIF XF8 MIDI 2 32:2 YAMAHA MOTIF XF8 YAMAHA MOTIF XF8 MIDI 3 32:3 YAMAHA MOTIF XF8 YAMAHA MOTIF XF8 MIDI 4 MIDI recording and playback work fine, but now I want to know if it can be made to work as a soundcard. I know that the Motif XF can work as a USB audio interface on Windows and Mac. Here, it even happens to be listed as one in "/proc/asound/cards" $ cat /proc/asound/cards 0 [PCH ]: HDA-Intel - HDA Intel PCH HDA Intel PCH at 0xf7910000 irq 42 1 [NVidia ]: HDA-Intel - HDA NVidia HDA NVidia at 0xf7080000 irq 17 2 [Loopback ]: Loopback - Loopback Loopback 1 3 [VirMIDI ]: VirMIDI - VirMIDI Virtual MIDI Card 1 4 [XF8 ]: USB-Audio - YAMAHA MOTIF XF8 Yamaha YAMAHA MOTIF XF8 at usb-0000:00:1a.0-1.2, full speed but, problem is, it doesn't show on "aplay -l" nor "arecord -l" (nor any other audio app for that matter). $ aplay -l **** List of PLAYBACK Hardware Devices **** card 0: PCH [HDA Intel PCH], device 0: ALC662 rev3 Analog [ALC662 rev3 Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: PCH [HDA Intel PCH], device 3: HDMI 0 [HDMI 0] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: NVidia [HDA NVidia], device 3: HDMI 0 [HDMI 0] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: NVidia [HDA NVidia], device 7: HDMI 1 [HDMI 1] Subdevices: 1/1 Subdevice #0: subdevice #0 card 2: Loopback [Loopback], device 0: Loopback PCM [Loopback PCM] Subdevices: 8/8 Subdevice #0: subdevice #0 Subdevice #1: subdevice #1 Subdevice #2: subdevice #2 Subdevice #3: subdevice #3 Subdevice #4: subdevice #4 Subdevice #5: subdevice #5 Subdevice #6: subdevice #6 Subdevice #7: subdevice #7 card 2: Loopback [Loopback], device 1: Loopback PCM [Loopback PCM] Subdevices: 8/8 Subdevice #0: subdevice #0 Subdevice #1: subdevice #1 Subdevice #2: subdevice #2 Subdevice #3: subdevice #3 Subdevice #4: subdevice #4 Subdevice #5: subdevice #5 Subdevice #6: subdevice #6 Subdevice #7: subdevice #7 Trying to force using it as soundcard (based on info from "/proc/asound/cards") doesn't work either. For example: $ aplay -D plughw:XF8 file.wav aplay: main:722: audio open error: No such file or directory Same result with "plughw:4" instead of "plughw:XF8". I read that problems like this could happen if the USB soundcard was plugged into a USB 3.0 port. Indeed, I have USB 3 ports here, but I tried plugging it into USB 2 ports and the result was the same. More command outputs: $ lsusb Bus 001 Device 002: ID 8087:0024 Intel Corp.

Anything else I can try? Googling about using the Motif XF on Linux, I found this: http://www.motifator.com/index.php/forum/viewthread/451381/ I also found this thread, but it's about MOX and not Motif XF: http://www.motifator.com/index.php/forum/viewthread/458166/ which lead me to this patch: http://www.mail-archive.com/alsa-user@xxxxxxxxxxxxxxxxxxxxx/msg28116.html The discussions are a bit old, but it seems that the patch was included upstream and MOX is working. Maybe the problem with the XF is similar? -- ____________________ Blog: http://aiyumi.warpstar.net/ _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
