Some additional notes follwing more testing (takes a reboot between tests)...
The problem seems to be isolated to pulseaudio running when an alsa reload is performed. If pulseaudio has not been stopped, sudo alsa reload will not properly initalize the card. If pulseaudio is stopepd and restarted either automatically or manually before the alsa reload event, it will report the card errors as seen above in the syslog, and the MIDI interface will still be nonfunctional. If, however, pulseaudio is stopped (and autospawn is set to "no"), an alsa reload will succeed, and restarting pulseaudio manually will bring back pulseaudio and the MIDI interface will be operating as it should. Therefore I'd put it down to an issue of pulseaudio starting or restarting before ALSA, and preventing the reload from properly initializing the MIDI interface. Just a guess, of course... someone more familiar with the stack will likely be able to pinpoint it better (I'm unfamiliar with the interactions between pulseaudio and ALSA). -- Pulse audio and ALSA failing to provide transport for MIDI interface https://bugs.launchpad.net/bugs/482902 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
