Status: RESOLVED WORKSFORME

(Core :: Audio/Video, defect)

[zhawk83]

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:33.0) Gecko/20100101 Firefox/33.0
Build ID: 20141113143407

Steps to reproduce:

Testing with this video: https://www.youtube.com/watch?v=FjgAb0nfgQM
Youtube has to be set to us HTML5 playback.
Scroll the video (best was to scroll into unbuffered areas).
After about 5-7 scroll the audio disappears.

I am using a Logitech G930. It is not a driver issue.
Firefox 33.1.1 does work fine.
I downgraded to 33.1.1 and there was no issue. Then upgraded again back to 34.0.5 and the issue appeared again. (I am now back at 33.1.1)
I have also used a clean profile with 34.0.5 and the issue was existent too.

This issue also appears when playing music but is much harder to reproduce.


Actual results:

playing music/videos that use html will end with no sound after some time. Only a restart of Firefox will help.
Youtube flash player version does work fine.
While the sound issue appears flash player viedos do have sound.
All other windows applications have sound.

I have found this site (https://gw2mb.com/archive.php) where sounds can be played.
FF 33.1.1 is fine.
FF 34.0.5 has the no sound issue after 1-3 songs and sometime after some tones.
FF 35.0 plays only like every 5-10 tone and missing out the rest. (No song can be recognized)
Since FF 35.0 I could not reproduce the sound issue with youtube.

But testing with the new site I can still see that FF 35 has issues with sounds.
