[Bug 772720] Re: extreme noise with sound
I'm now on Ubuntu 16.04 xenial. VLC now actually plays music, but the UI freezes when I click play/select a file (so the music *is* playing even while the UI is frozen). MPlayer, Clementine et all do just fine on my machine. I'll enter another bug report for that. -- 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 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/772720/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Thank you for reporting this bug to Ubuntu. Ubuntu 11.04 (natty) reached end-of-life on October 28, 2012. See this document for currently supported Ubuntu releases: https://wiki.ubuntu.com/Releases We appreciate that this bug may be old and you might not be interested in discussing it any more. But if you are then please upgrade to the latest Ubuntu version and re-test. ** Changed in: pulseaudio (Ubuntu) Status: Confirmed => Incomplete -- 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 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/772720/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 772720] Re: extreme noise with sound
my 2 cents - I played with alsa/pulse switching in the options... the same noise. then I turned the Dolby surround off ( was Auto before that ) - noise. ( After each )settings change I restart vlc ) Finally I turned the dolby surround on and - no noise initially but on the second restart noise again. After I hear the noise if I rewind forward on back or if I pause and resume or I play with the playback speed I can stop the noise but it comes again in 10 secs usually bye bye vlc - will look to use another player for a while until someone fixes it. I can fund this bugfix with 50 euro if somebody can fix it ubuntu precise on a dell xps 15 l502x with xfce4 -- 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 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/772720/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 772720] Re: extreme noise with sound
FWIW, I think this symptom is another manifestation of the various corrupt databases that pulse doesn't deal with gracefully. Honestly I don't think this is going to be fixed in a backward-compatible manner; there have been recent git commits to add tagstruct versioning to the db files. -- 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 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/772720/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 772720] Re: extreme noise with sound
VLC 1.1 does software volume internally (according to the volume level in the VLC UI). The base levels have not changed since ages, and are the exact same for either ALSA and PulseAudio output plugins. (This will change in VLC 1.2 that integrates with PulseAudio volume control but Ubuntu is not there yet.) From your bug description, it sounds like PulseAudio (or a PulseAudio volume control application) is setting the default volume of VLC streams too high - when VLC outputs directly to PulseAudio via libpulse that is. ** Package changed: vlc (Ubuntu) = pulseaudio (Ubuntu) -- 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 ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 772720] Re: extreme noise with sound
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 ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 772720] Re: extreme noise with sound
I'm able to reproduce it using my backups. It seems to be related to the volume levels, as you've suspected. == Trials == Conditions: Time A ... configuration from where I filed the bug Time B ... configuration from my post where I haven't been able to reproduce it anymore Config file V ... config file of vlc ($HOME/.config/vlc/*) Config file P ... config and state files (incl. volume levels) of pulse ($HOME/.pulse/*) So let's mix these. First trial period consists of all the possible combinations: AV+AP: noise AV+BP: noise BV+AP: noise BV+BP: no noise However, using the new config BV seems to alter something important in P: 1) fire up BV+AP, result: noise After vlc started, the pulse config/state file 657b92791ebe658fba9f363b4ba14252-stream-volumes.tdb has changed 2) Now firing up vlc yields some very subtle noise at the very begin of playing, but overall 'no noise'. 3) Afterwards there's not even subtle noise at the beginning I've attached both versions of the stream-volumes.tdb == Conclusions == Looks like pulse has ceased to run fine with some stream-volume settings which it had set on its own in a previous version. == Messages == Observation unrelated to above's trials: The following message is shown on console independent on whether there is noise or not: [aac @ 0x1b63650]Transition from an ONLY_LONG or LONG_STOP to an EIGHT_SHORT sequence detected.
