I got the same on Audigy 2 ZS Notebook. I described it here https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/503165 . It's definetely rather case of alsa rather than pulseaudio.
Anyone can take care of this, please ?! I think this consider most of the people with emu10k1 based cards! -- Popping or clicking sound in Audigy 4 https://bugs.launchpad.net/bugs/464949 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
