Hi, ok, David, can you (we) focus only on vibrating noise from channels? I am not sure if "rewind due to underrun" was not my fault.
I have filed another bug long time ago, because my sound sometimes went away completely. I was really desperate and thought this was pulseaudio issue. But by accident, I managed to find out, that the culprit was my fan on my motherboard's chipset few days back. It was old and sometimes did not cool temperature from chipset enough because the it did not rotate. I can tell you that I can fry my steak on it. I use 5.1 onboard sound card, so chipset disliking hot "weather" was destroying the sound according to the random fan cooling capabilities. So I've greased the fan as hell (we have closed reported bug also), and problem with slowing sound disappeared. HEUREKA! But unluckily, the vibrating problem is still here. So what I did again (if it can help) is what I have written in #6. I was able to run mp3 and movies (still with vibrating problem) successfully this time. I'm enclosing file. To be sure with correct no simd invocation, I ran this command: LANG=C PULSE_NO_SIMD=1 pulseaudio -vvvv > ~/pulseverbose2.log 2>&1 I first ran your #3 stuff with 6 channels (merged to final mp3 - but I have also audacity project saved), than ran some mp3 and also one 5.1 fullHD movie. ** Attachment added: "pulseverboseNEW.log" https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/772738/+attachment/2121717/+files/pulseverboseNEW.log -- 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
