Did a little more testing here: On my laptop, with an Intel HD 4400 Graphics, I do have sound on both videos posted above with Firefox 50.0b9. On my PC, the situation is a little more complicated: With Firefox 49.0.2, the sound playback on both videos works normally. With Firefox 50.0b9, there is NO sound playback. Only if you scroll through the video, you get sound for about a tenth of a second, then it stops again. When I downgrade Firefox 50.0b9 to 49.0.2 (same profile, no other changes), the sound playback is working again like normal.

Forgot to tell: PC has a NVIDIA GeForce GTX1060 as you can already see in my posted about:support data.

I did some even more testing ;): The error started in 50.0b9 on my PC with NVIDIA GeForce GTX 1060. With 50.0b8 the sound playback is workling normally, when I update it to 50.0b9, the sound is missing. As soon as I downgrade to 50.0b8, the sound playback is back again. During the tests I did not change anything else, no drivers etc. and always used the same Firefox profile. There has to be some changes from 50.0beta8 to beta9 that causes the sound playback to stop on certain videos. The same change has to be in the latest nightly and dev-builds, as there is also no sound playback with the latest builds.

Cour you run the mozregression tool available there: http://mozilla.github.io/mozregression/ Enter that 49 worked and 50 doesn't.

/Done. The error occured on nightly-build 2016-10-04 fist. nightly-build 2016-10-03 was still ok.

just providing the result would have been easier to decipher, it would be something like: regression range: blah. right now, I can't make sense of any of that.

I'm experiencing a similar audio issue with 50.0b9 and 51.0a2 having the same symptoms as described by Kai. After fiddling with pretty much every setting, I narrowed it down to the sample rate setting in Windows. As long as this sample rate is identical to the audio stream you're listening to everything is fine. However, when the sample rates differ (e.g. Windows @ 44.1kHz and audio @ 48kHz) there is no sound. I used some test videos from here: http://kb.mozillazine.org/Testing_plugins#HTML5_audio_and_video The first link points to a 44.1kHz (Toy Story) video, the last link is 48kHz (Lego heli). Setup: Windows 8.1 x64, Nvidia GTX770, Creative X-Fi @ 5.1 using 24bit/48kHz.

In the speaker setting, I changed the sampling rate from 44.1kHz to 48kHz, and in each case audio played nicely.

can't reproduce in mozilla beta either. To play with the sampling rate not matching what was set in windows, you can use this: in about:config, right click to create a boolean preference media.resampling.enabled and set it to true. create an integer preference media.resampling.rate and set it to 32000 I always get audio playback. are you guys using an hdmi connection for audio out rather than analog speakers?

I see the mozregression range are dubious. The only thing that changed between 50b9 and 50b8 cubeb-wise is bug Bug 1310206. Which suspiciously has "- bug 1295193, bug 1300650, two issues related to setups that have different input and output sample rate" seems to match the regression cause. input rate not matching output rate.

Trying to narrow the changes. The people affected could you try this build: Win32: https://archive.mozilla.org/pub/firefox/tinderbox-builds/mozilla-beta-win32/1476795321/firefox-50.0.en-US.win32.installer.exe Win64: https://archive.mozilla.org/pub/firefox/tinderbox-builds/mozilla-beta-win64/1476795321/firefox-50.0.en-US.win64.installer.exe And see if it has the problem is fixed... And to confirm, that with this build (that includes changes from bug 1310206), does break audio: Win32: https://archive.mozilla.org/pub/firefox/tinderbox-builds/mozilla-beta-win32/1476796761/firefox-50.0.en-US.win32.installer.exe Win64: https://archive.mozilla.org/pub/firefox/tinderbox-builds/mozilla-beta-win64/1476795321/firefox-50.0.en-US.win64.installer.exe thank you

I suppose we can simply back-out the ceilf -> roundf line, but I'd like to be able to replicate the reporter's setup. It works on all my machines, regardless of the sample-rate I choose.

No, I'm using the analog output on my Creative X-Fi Titanium Fatal1ty Pro.

Paul has requested that the patch on Bug 1310206 be backed out to fix this issue. I'm officially linking the 2 bugs in bugzilla for tracking and clarity.

I don't think we need to back out all of it, just the ones from comment 23. The change is much narrower than all of 1310206 as confirmed by the people who tried the builds above.

there are two commits between the working vs non working https://hg.mozilla.org/releases/mozilla-beta/rev/3c7b927f4b0b https://hg.mozilla.org/releases/mozilla-beta/rev/fa324ad9a0cb9bc27a2509aef5d220ae46338b8d Seems that only - return (uint32_t)ceilf((output_frame_count - samples_to_frames(resampling_out_buffer.length())) + return (uint32_t)roundf((output_frame_count - samples_to_frames(resampling_out_buffer.length())) * resampling_ratio); Is the change that could explain the regression

Bug 1312056 requires only the roundf -> ceilf change, too (https://bugzilla.mozilla.org/show_bug.cgi?id=1312056#c1).

The other lines are not used (we since disabled duplex on beta/windows), I'd be more comfortable returning to the exact same state as before beta 9. I don't forsee any issue, but better safe than sorry.

Recent regression in beta, tracking for 50
