789247 - ogg vorbis playback broken in firefox-15.0-1.fc16.x86_64

Status: RESOLVED DUPLICATE of bug 779392

(Core :: Audio/Video, defect)

Description

[Ian Malone]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:14.0) Gecko/20100101 Firefox/14.0.1
Build ID: 20120801071420

Steps to reproduce:

See Fedora bug: https://bugzilla.redhat.com/show_bug.cgi?id=854771

On updating to firefox-15.0-1.fc16.x86_64 sound clips on http://www.russianlessons.net/lessons/lesson2_main.php (e.g. http://www.russianlessons.net / audio / lesson3-13.ogg : I've broken the link because I doubt they'd appreciate direct linking to media files) are broken. Downgrading to xulrunner-14.0.1-3.fc16.x86_64 + firefox-14.0.1-2.fc16.x86_64 works and confirms the problem is somewhere in the FF15 packages.

Version-Release number of selected component (if applicable):
firefox-15.0-1.fc16.x86_64

How reproducible:
100%

Additional info:
Downloading the ogg file and playing in ogg123 is fine, oggz-validate and oggz-info show no problems with the file, plays okay in the earlier Firefox.
Other ogg files seem to work okay, may be an issue with the sample rate (22kHz, rather than 44k or 48k).


Actual results:

1. Visit site, click the green 'play' buttons, only a 'clipped' burst of sound occurs, same visiting the ogg link directly (so not a problem with the presence of mp3 alternatives).


Expected results:

Expected results:
Sound clip plays.

Okay, I've tried a few things and there's a complicated picture:
Mozilla binaries from http://releases.mozilla.org/pub/mozilla.org/firefox/releases/ EN-US x86_64 builds:

firefox-15.0.tar.bz2
firefox-15.0.1.tar.bz2
firefox-16.0b2.tar.bz2
- Broken on all of these.

firefox-14.0.1.tar.bz2
- Works on this.

Additionally, on my laptop on F17 Firefox 15 works okay.

Messages to console while trying to play the files in Firefox 15:
nsBuiltinDecoderStateMachine::RunStateMachine queuing nsBuiltinDecoder::PlaybackEnded
nsBuiltinDecoder::PlaybackEnded mPlayState=3

- but I don't seem to get those when playing ogg files that do work.

Difference in hardware and file dependence still suggests something sample-rate related.

It works OK for me using Firefox 16 beta 2. Does it still happen if you run Firefox in Safe Mode?

Comment 3

Yes, it still happens in safe mode and with all plugins disabled.

Comment 4

[Virgil Dicu [:virgil] [QA]]

Similar to bug 789726. Could you answer the requests in comment 2 in that bug?

Comment 5

[Ian Malone]

media.use_cubeb=false works for me (toggling it toggles between broken and working). I've posted the alsa-info in bug 789726 as it seems to be the same thing.

Comment 6

[Matthew Gregan [:kinetik]]

It turns out that this issue is different to the one reported in bug 789726.  This one's related to the latency handling issue with the alsa-pulse plugin and PulseAudio, which should be resolved by bug 779392.  Ian confirmed in bug 789726 comment 13 that the test build linked from bug 779392 worked for him, so I'm going to dupe this bug against that one.
