@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 Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/902497 Title: ALSA Support for Roland GAIA SH-01 Synthesizer Status in linux package in Ubuntu: Fix Released Bug description: Please add support for Roland GAIA SH-01 Synthesizer from sound tree to kernel. http://git.kernel.org/?p=linux/kernel/git/tiwai/sound.git;a=commit;h=ae7cc709f2ec11b49fc31b20cd8c943794ae9576 ProblemType: Bug DistroRelease: Ubuntu 10.04 Package: linux-image-2.6.32-36-generic 2.6.32-36.79 Regression: No Reproducible: Yes ProcVersionSignature: Ubuntu 2.6.32-36.79-generic 2.6.32.46+drm33.20 Uname: Linux 2.6.32-36-generic x86_64 NonfreeKernelModules: nvidia AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.21.
