Those latencytop numbers seem very healthy to me, but I'm not an expert with latencytop. When you run latencytop, make sure the audio application is selected on the bottom half of the screen. Since your system as a whole seems fairly responsive, the top half of the screen (overall system) is less important than the bottom half of the screen (the selected application). You can check "vmstat 1" or "top" to see if anything is running in the background. You shouldn't get audio stuttering from a modest system load, unless one of the apps is misbehaving.
This may be a hardware driver issue for something that is in the docking station (possibly not the audio driver). You might compare "lsmod" when you boot up docked versus undocked, to see if there are additional modules loaded for one configuration (also lspci, etc). It sounds like the "bad" driver isn't being loaded when you boot up undocked. You can also try "dmesg" instead of /var/log/messages, which sometimes gives more detail. When you boot up in/out of the dock, are you doing a cold boot, or could this be related to suspend/resume? -- Rhythmbox stutters with no system load at all https://bugs.launchpad.net/bugs/330398 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
