Package: iceweasel Version: 10.0.1-1 Followup-For: Bug #585149
In message #5 of this bug, Jad Zoghaib directs our attention to this video (which will not play with audio in the case of that PPC system): http://videos.mozilla.org/firefox/3.5/meet/meet.ogv On my system, that plays audio (and video) just fine. And yet, on my system, none of the OGV videos from DebConf 11 will play sound (only video): http://ftp.acc.umu.se/pub/debian-meetings/2011/debconf11/high Since some WebM and OGV files will play (with sound) in the Iceweasel browser, I can rule out some possible causes I mentioned in message #71: 0) It's not specifically related to architecture (amd64, in my case). 1) It's not caused by cruft in my .mozilla config directory -- I blew that away today, but the problem with no sound in some WebM and OGV videos (while sound plays fine in others) remained. 2) I use a custom kernel and custom X stack, so I thought this might be breaking things. But sound works in general -- including 5.1 surround, simultaneous playback of as many sound sources as I like via ALSA dmix, Flash videos in Iceweasel, and other files with sound in Iceweasel -- so it cannot be my custom packages causing this problem. (Besides, other users started this bug report, and they are not using custom built packages AFAICS.) 3) I have a custom, system-wide /etc/asound.conf file, and because of problems I had with previous software I guessed that either this (or initialization of sound in Iceweasel) would be the problem. I was wrong: if any of the breakage was caused by this, sound would never have worked with any of the videos... but I have found many that _do_ work. 4) This cannot be blamed on debian-multimedia.org, since sound will play correctly with some videos. (I've had conflicts resulting from mixing Sid and d-m.o before, and that usually results in total breakage.) I spent some time on bugzilla.mozilla.org, and could not find recent bugs which involve video playback without audio. My impression is that Linux gets secondary attention in this area, likely because of the history of confusion in Linux sound support; however, this seems less like a problem with sound so much as some sort of confusion in the browser about whether it can support playback of the problem videos (or, at least the audio part of those videos). Not sure how to proceed at this point. DW -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe". Trouble? Contact [email protected]
