I can confirm the bug exactly as described. However my .mkv files have mpeg 1 layer 2 sound (stereo, 128 kbps, 48000 Hz). Video is H264. When the file is .mp4 with video H.264 / AVC and sound MPEG-4 AAC audio, there's no problem.
Also I have noticed that in order to thumbnail the troublesome videos, i must sometimes delete the folder ~/.thumbnails/fail/. Can I provide any further info for debugging? -- totem loses sound when seeking in mkv which has embedded mp3 layer https://bugs.launchpad.net/bugs/424283 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gstreamer0.10 in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
