I've just tried to prove your assumption. I came to no clear conclusion, but to a fine, noiselessly playing vlc. I am confused, which is why I'll just describe my observations.
The only constant for all my trials is that the visual part of video with pulse and audio+visual part of video with alsa worked fine in all conditions. What did I do? I upgraded pulse to 1:0.9.22+stable-queue-24-g67d18-0ubuntu3.1. -> audio with noise -> additional observation (didn't observe this before, I guess I would have noticed, but neither specially checked for it): When sliding forward in video from position (A) to position (B), video plays from (B), audio plays from (B), but *additionally* for about 5 secs audio from (A) is still played simultaniously I lowered the volume level of vlc from 130 % to 75 % and restarted vlc, so it started with 75%. -> audio with noise I set "Dolby Surround" to "off"; previously it was "auto" (I do only have two stereo boxes). -> audio without noise, no other problems, everything is fine! I set "Dolby Surround" to "on" (expecting the noise again). -> audio without noise I set "Dolby Surround" to "auto", setting volume to 130% (expecting the noise again). -> audio without noise As said, vlc does now play fine with pulse and I can't reproduce the problem anymore. (Vague idea: While I continously update my software, my /home including config files are never reset. Might there be some sound releated configuration option not directly set from the GUI, but indirectly (option dolby surround automatically sets someBufferSetupInternalOption to 2d9a92f) and some old indirect value survived, hasn't been consistent with the controls visible in the new vlc's GUI, but has been used anyway? - I'll get the backup of my data and investigate). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/772720 Title: extreme noise with sound -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
