@Micah Gersten: The problem still remains with an empty profile, like keinerwieder, and also within Firefox safe mode. @keinerwieder and others that may have this issue: I made some tests and I would like your help to see if the errors apply to other people. Can you please test if the videos/animations work with no sound system working at all? Just close all browsers instances, run the following commands and test with some Youtube or other video that used not to work: Edit /etc/pulse/client.conf and add the line "autospawn = no" to it, without the quotes, of course. $ sudo service alsasound stop $ pulseaudio -k Make sure that pulseaudio is not working, so run "ps aux | grep pulse". No /usr/bin/pulseaudio should be listed. Try some flash videos now. Send us a feedback telling if the video worked. Thanks!! PS: to get sound working again, remove the line added to /etc/pulse/client.conf and restart the system. @all: I had some guesses of what was causing this issue. I'm quite sure it is some sound related problem. Quite sure that it's not a Firefox problem as well, because this affects Epiphany and Konqueror too. And maybe affects other players like Totem, as I will add some example later. Anyway, I don't know if it's a Gstreamer problem, Pulse, Alsa or the connection module between Pulse and Alsa. First let me explain what happens to me: I try to watch an Youtube video; it starts loading and playing, with video and sound working perfectly; at some random point, sound and video stop; the button that indicates the video position jumps to some random time, seconds ahead, while I can see the "buffering" animation; the jump happens two or more times and Firefox freezes. If I try to watch a video at Youtube through Totem, exactly the same happens! Except that I can see the buffer loading a lot of times until 100%, the jump occurs, the buffer gets filled again and so on. With Totem I found how to get some debug messages with the following command: $ GST_DEBUG=*:2 totem --debug And at some point of the messages I get something like: 0:00:42.025612547 32291 0x962a8a0 WARN pulse pulsesink.c:523:gst_pulsering_stream_underflow_cb:<audio-sink> Got underflow After a while, the error happens and I get the prompt full of messages from ffmpeg dropping frames. With this warning from Pulse, I suspected about the audio system. I tried turning Pulse off, but the sound continues in Flash, as I think it uses Alsa. At Totem, with no sound, the video worked perfectly. So I turned off Alsa too, and got the video working at Firefox, obviously with no sound. At Firefox I get *a lot* of these lines with Pulse and Alsa off: ALSA lib pcm_direct.c:1494:(_snd_pcm_direct_get_slave_ipc_offset) Invalid value for card ALSA lib pcm_hw.c:1435:(_snd_pcm_hw_open) Invalid value for card Strangely, I can't get audio back in Firefox after starting Pulse and Alsa services again, I must restart the PC. I don't know why. I attached the syslog part of a session of pulseaudio run with --log- level=debug. An Youtube video in Firefox was started at 21:42:44 and the error happened around 21:43:35. Thanks for your help.
