[Bug 751265] Re: pulseaudio distorts VLC audio
I have this issue on a fresh install of 12.10 AMD 64. Sound was bad from VLC launch. Like others, this choppiness would eventually go away on it own (see #59) and come back some time later. I could also fix the problem with a pause and then unpause. Moving the mouse (#55) also seemed to fix the problem quite often. I moved VLC from default audio to ALSA and this got rid of the static / echo / choppiness. There was much rejoicing. However, I then picked up problem #60. This is a somewhat acceptable solution - I usually just use the menu playback - jump backwards to fix the problem as this gives a more precise amount of replay and I never encounter the bad audio. I tried the famous fix #23 and it made things worse. VLC would start with no sound for about 20 seconds. Moving the slider to a new point resulted in the same no audio problem. I backed that out right away. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/751265 Title: pulseaudio distorts VLC audio To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/751265/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 751265] Re: pulseaudio distorts VLC audio
It's all very confusing with many people experiencing similar symptoms. But the original logs look like a simple case of PulseAudio selecting a far too short latency: I: protocol-native.c: Final latency 201.00 ms = 0.50 ms + 2*100.00 ms + 0.50 ms D: alsa-sink.c: Cutting sleep time for the initial iterations by half. D: alsa-sink.c: Latency set to 0.50ms And indeed, VLC version 1.1.8 requested tlength=200ms and minreq=100ms. A similar problem affects more recent VLC versions with tlength=40ms and minreq=-1 (overriden by PA to 20ms). It seems that when tlength is exactly twice minreq, PulseAudio settles on an insanely small latency. That causes frequent underrun in hardware buffers, accounting for the distorsion. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/751265 Title: pulseaudio distorts VLC audio To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/751265/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Did not have the issue in 12.04, but I have the issue now on 12.10. However the issue is not present if the program pavucontrol is running at the time I start VLC and I leave it running. Also if I request VLC to ouput via ALSA, the issue is no present but I get another weird bug (I don't know if they are related): when I pause the video and I play it again, I don't get audio from VLC anymore.

[Bug 751265] Re: pulseaudio distorts VLC audio
Thanks for answer #23, it solved my problem. The problem occured only by VLC itself and the KDE Phonon VLC module. So I suspect that VLC is doing something a little bit different than most other audio backends. Maybe the chunk size VLC uses or the timing of VLC. Also I followed https://wiki.archlinux.org/index.php/PulseAudio#Choppy.2C_overdriven_sound (set samplerate to 48000 Hz) and https://wiki.archlinux.org/index.php/PulseAudio#Setting_the_default_fragment_number_and_buffer_size_in_Pulseaudio (Set correct buffer and fragment size for 48000 Hz).

My five cents: I just upgraded to Kubuntu 12.10 beta 2 AMD64 with full updates and the awful cracking/echoing noise is still present in both VLC 2.0.3 and Skype 4.0.0.8 x64. My system is AMD based with 785G chipset. * The ¨rm ~/.pulse -rf¨ worked only for seconds until I closed and reopened VLC; no changes in Skype. * The solution at #23 solved inmediatly the cracking for both apps. On any case I'm still scared of how OLD this problem is. Come on, we are in 2012 and this thing is still chasing us five years later.

[Bug 751265] Re: pulseaudio distorts VLC audio
Long time I have used this account. This problem happened in LinuxMint Debian Edition - the core files are from debian. This is not Ubuntu related, and upstream trouble. How I recieved this crispy, fuzzy sound: - I have edited /etc/pulse/daemon.conf and increased fragment amount and msec. This should reduce delays in slower apps (wine). - next, I killed pulse audio (ps aux|grep pulse; kill -15 xxx) Immediate result is this crispy, fuzzy audio in VLC, but even in OpenArena 0.8.8. In VLC it disappears if I increase/decrease volume, but reappears if I restart VLC, change different media or navigate. In Openarena it disappears after 10 seconds. This looks like a problem with buffers to me. The solution #21 rm -r ~/.pulse solved the issue. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/751265 Title: pulseaudio distorts VLC audio To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/751265/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 751265] Re: pulseaudio distorts VLC audio
I can confirm that removing .pulse directory does *not* solves the problem for me :-( But I found an empirical solution that is perfectly reproducible for me and maybe can shed some light on the problem: 1. start playing an mp3 with VLC - sound is distorted/crackling 2. while VLC is playing, kill pulseaudio with 'pulseaudio -k' 3. obviously VLC is not happy and crashes 4. restart VLC and... voilà.. the sound is perfectly clear from now on, even after suspend/resume cycle !!! Note that simply killing pulseaudio withouth VLC playing does not work (at least for me). This trick also solves the similar audio crackling problem with Skype new version which was unusable for me before! Maybe there is a problem of pulseaudio initialization for some applications?

I also have this problem, after a clean 11.04 install. VLC was not installed on my system when i noticed a distorted sound in Skype, like the one in the above file, and an echo. My mic was shut off using a hardware switch, so looping sound did not cause this. The microphone also does not work in Skype, but can be looped back to the speakers, using ALSA.

David, thanks for your quick response. I think I can shed some light on this issue. I solved the problem by going into VLC Tools Preferences Audio. I changed the Output module from the default (Pulseaudio, I assume) to ALSA and the distortion went away. While playing VLC, this change shows in the taskbar sound manager in Preferences Applications. Instead of saying VLC media player, it now says ALSA plug-in [vlc].

Hi Blaine and thanks for your bug report. I tried vlc here but could not reproduce it, and I'm not sure what could be causing it.
