If you don't mind, we need to gather a bit more information to help determine how to proceed.
Seeing as you are able to determine this isn't specific pulseaudio, we can start by following the instructions at https://wiki.ubuntu.com/DebuggingSoundProblems#Automatic%20Sound%20Information%20Collection. Can you please go to http://alsa-project.org/alsa-info.sh, download the shell script and run it as "bash alsa-info.sh" and copy the URL it returns into this ticket? Please let me know if you need help with this step. Seeing as I am also experiencing a similar issue, here is my output: http://www.alsa- project.org/db/?f=a7e9a92e8c0fa0e40779c417a1b75c403fbda565 ** Changed in: ubuntu Status: New => Incomplete -- bad sound (excesive resources consumption, choppy sound...) https://bugs.launchpad.net/bugs/333252 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
