@Stefan, I seem to recall some issues playing audio from the GAIA to my system, but haven't used it in while. I'm not sure what those "square.roam.corp.google.com" entries in your logs are. You are using all of the right debugging techniques and the problem might be related to the type of USB quirk entry.
Post a question on the alsa-devel mailing list and they will help more than here. -- 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
