Hi, I have a netbook toshiba nb305, I have the same problem. I think I resolve the problem. (sorry for my basic English).
I download from the Software Center of Ubuntu the "PulseAudio preference". After installing, then i go to menu system>preference>pulseAudio preference. In PulseAudio Preference I go to "simultaneous output" and check the box "add a virtual output device for simultaneous release of all the board of local sounds". After I go to menu system>preference>sound and go to "output". In "output", I check the box "Simultaneous output to audio interno Analog Stereo". Try This! -- ubuntu-bug alsa-base Popping Clicking Pulse Audio crashing https://bugs.launchpad.net/bugs/551949 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
