Hi David, of course it is. Thanks for helping. I am not sure if I got you:
1. I ran your command and yes the sound is weird - bronken 2. I ran audacity with this configuration: ALSA-pulse-default: Line:0 - 1(Mono), I start recording (that is the "broken" part in my file starting from 0s to 12s) 3. I ran pavucontrol and set monitor source; suddenly, sound looks better (from 12 sec to the end) In fact, sound has pretty "constant" graph in audacity (I've tried also setting "6" instead of "1(Mono)) - but 2 speaker channels (rear and front right) still vibrate - fluctuate (problem still presents). This is strange, isn't it? If I can help more, please, do let me know. Once again, thanks! ** Attachment added: "MonoSound(mp3)" https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/772738/+attachment/2106877/+files/testSound.mp3 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/772738 Title: PA 5.1 surround vibrate(oscilate, vary) -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
