View Full Version : [ubuntu] Video plays too fast

February 8th, 2011, 09:59 PM
Ever since I upgraded to Ubuntu 10.10, I have had trouble playing sound and video.

Videos play too fast for me. I don't think it's a Flash problem because it occurs no matter what kind of video I play: Browser-based videos like YouTube, or Totem with .wmv files , .avi files, etc.

Recently I discovered something interesting: In my sound preferences, if I switch the output from "[SB Live! Value] EMU10k1X Analog Stereo" to "Internal Audio Analog Stereo", then videos play at normal speed, but with no sound. So, I have a choice between too-fast videos with sound or normal speed videos with no sound. Obviously, neither of these is acceptable. Again, I never had this problem until I upgraded to Ubuntu 10.10.

Any help? I know nothing about this stuff so please explain what to do as if you were talking to a beginner.

I have the very same issue, I've tried lots of solutions from lots of threads. I haven't had any luck yet. Along with the video playback issues i have no sound over hdmi.

same problem. With firefox, chromium, opera. used many flash plugins nothing works. I'm reduced to downloading and viewing later. Plays fast, no sound.

I was able to figure it out. Looked at a few different threads and saw that it was either a Flash Plugin issue or a sound issue.
I tried using the Firefox Add-on Flash-Aid (https://addons.mozilla.org/en-US/firefox/addon/flash-aid/) but that didn't fix my problem.
Then I went into my sound settings and made changes so that the selected hardware would then be correct. (I changed from digital HDMI output to the analog speakers - I don't use the HDMI in my set-up).
Fixed everything. Videos play normal speed with sound.

Hello there!

I have the exact same problem, and no solution working. Thing is, Pavucontrol only shows the HDMI output, which I don't use, and with that videos are running way too fast anyway (any kind of videos, from flash ones to VLC.) So I shut it down, now videos are running well, but still witout any sound, as ubuntu can't see my analog output (or maybe it sees it, I hope so anyway, but I don't have it in my sound options.)

I ran many commands I've found in some various forums and so.

I'm sorry it's in french, I tried in the french forum, but got no answer. Maybe someone can help here...

I'm using Ubuntu 12.10 64 bits. The audio/video outputs are all integretad on an Asus M5A78L-M/USB 3.0 motherboard...
