[linux-audio-user] midisport snd-usb-audio mysteries

My M-Audio Radium 61 is on the fritz again. With the recent changes in udev, where udev replaces hotplug, I had to do some trickery to get the firmware to load. When it finally did, it dumped me into a problem I've seen many times before: the keyboard is recognized as existing by the ALSA sequencer, but there doesn't seem to be any midi data coming from it (neither zyn nor aseqview). Unplugging, powering off, etc. yields no different result. Converseley, when it's working fine I can unplug, power off, etc. and it always comes back just fine. Well, always except for the time when it decides to go awol. I've also tried unloading snd-usb-audio. In the past the problem has been resolved by rebooting, but I'm feeling adventurous and don't particularly need to use the keyboard at the moment, so I think I'll try to track it down. So my question is, where does the problem most likely lie? Is the firmware perhaps not loading properly for some reason? Is something in one of the ALSA kernel modules in a strange state? snd-usb-audio, or one of the other snd- modules, or maybe the *hci modules? -- Hans Fugal ; http://hans.fugal.net There's nothing remarkable about it. All one has to do is hit the right keys at the right time and the instrument plays itself. -- Johann Sebastian Bach
