Giving a short re-summary of the problem: when using rhythmbox, if a user changes the system volume by using function keys or "special" volume keys (such as the ones HP puts on their laptops these days), the system will temporarily hang. Sound continues to play with no problem.
When I intentionally force this bug to happen with a system resource monitor open, the resource monitor will continue to stream and show that nothing unusual is happening; that is, there are no resource hogging events going on, at least from the system monitor's report. However, this problem seems to block all non-system processes. For example, if I invoke this bug, rhythmbox will freeze, but I will still be able to switch desktops and use system menus. However, other running processes (such as firefox or gedit) will be frozen as well. All non-system processes unfreeze at the same time, somewhere around 5-15 seconds after the problem starts. As noted before in previous bug comments (https://bugs.launchpad.net/ubuntu/+source/rhythmbox/+bug/144330), this problem occurs exclusively when two things are true: 1)Rhythmbox has focus (i.e. isn't minimized), 2)Rhythmbox's "Browse" window is open (accessible via View->Browse) and has never been closed. I've noted that if you open Rhythmbox, then close the "Browse" window and re-open it, this problem goes away. However, this problem seems to randomly return every few weeks, and I cannot figure out a pattern causing it to return. To recreate this bug yourself, do the following: 1)Open rhythmbox, 2)Ensure that the "Browse" window is open (menu: View->Browse), 3)Begin playing a song, 4)Change the volume using a function key. Again, the problem seems to be intermittent based on the usage of the "Browse" window. The problem may also be related to the amount of songs Rhythmbox is keeping track of. I have ~5000 songs in my library, so there may be a problem related to the browse window reading a large song list. Note that I have NOT tried running rhythmbox from the command line and invoking this bug to see what errors pop out. Why? Because whenever the problem crops up I instinctively "fix" it by closing and opening the "browse" window before I remember to try logging the error. My apologies. ** Attachment added: "browse_window.png" http://launchpadlibrarian.net/18820433/browse_window.png -- Rythmbox freezes when using keyboard volume keys https://bugs.launchpad.net/bugs/250695 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
