I am on 14.04, and there is still something wrong with it. The midi part work, but audio works only from the computer to the GAIA, the audio that is played from the GAIA to the computer does not work (only getting silence).
When I turn on the synthesizer I get these in the /var/log/messages: Jul 7 22:01:45 square.roam.corp.google.com kernel: [ 1526.365531] usb 4-1.5: new high-speed USB device number 8 using ehci-pci Jul 7 22:01:45 square.roam.corp.google.com kernel: [ 1526.459063] usb 4-1.5: New USB device found, idVendor=0582, idProduct=0111 Jul 7 22:01:45 square.roam.corp.google.com kernel: [ 1526.459084] usb 4-1.5: New USB device strings: Mfr=1, Product=2, SerialNumber=0 Jul 7 22:01:45 square.roam.corp.google.com kernel: [ 1526.459087] usb 4-1.5: Product: SH-01 Jul 7 22:01:45 square.roam.corp.google.com kernel: [ 1526.459090] usb 4-1.5: Manufacturer: Roland Jul 7 22:01:45 square.roam.corp.google.com mtp-probe: checking bus 4, device 8: "/sys/devices/pci0000:00/0000:00:1d.0/usb4/4-1/4-1.5" Jul 7 22:01:45 square.roam.corp.google.com mtp-probe: bus: 4, device: 8 was not an MTP device Jul 7 22:01:45 square.roam.corp.google.com kernel: [ 1526.520043] usb 4-1.5: Unable to change format on ep #84: already in use Jul 7 22:01:45 square.roam.corp.google.com kernel: [ 1526.520076] usb 4-1.5: Unable to change format on ep #84: already in use Jul 7 22:01:45 square.roam.corp.google.com kernel: [ 1526.520110] usb 4-1.5: Unable to change format on ep #84: already in use Jul 7 22:01:45 square.roam.corp.google.com kernel: [ 1526.520296] usb 4-1.5: Unable to change format on ep #84: already in use > aplay -l **** List of PLAYBACK Hardware Devices **** card 0: PCH [HDA Intel PCH], device 0: ALC269VC Analog [ALC269VC 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 0: PCH [HDA Intel PCH], device 7: HDMI 1 [HDMI 1] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: PCH [HDA Intel PCH], device 8: HDMI 2 [HDMI 2] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: SH01 [SH-01], device 0: USB Audio [USB Audio] Subdevices: 1/1 Subdevice #0: subdevice #0 > arecord -l **** List of CAPTURE Hardware Devices **** card 0: PCH [HDA Intel PCH], device 0: ALC269VC Analog [ALC269VC Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: SH01 [SH-01], device 0: USB Audio [USB Audio] Subdevices: 1/1 Subdevice #0: subdevice #0 > amidi -l Dir Device Name IO hw:1,0,0 SH-01 MIDI 1 IO hw:1,0,1 SH-01 MIDI 2 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/902497 Title: ALSA Support for Roland GAIA SH-01 Synthesizer To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/902497/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
