This issue also occurs on Flame 2.5

The audio will sound like it is skipping while using the scrubber.

This issue does not occur on Flame 2.2 

The music keeps playing smoothly while the user is moving the scrubber and no "skipping" occurs.

I'm hoping to address this in Bug 996410.

Not requesting blocking on this issue as it seems pretty minor.

Comment 5

[Justin D'Arcangelo [:justindarc]]

I've just posted a patch for Bug 996410 which takes advantage of the HTMLMediaElement.fastSeek() API. Unfortunately, seeking still sounds not great with certain files. I'm guessing that this is possibly a codec issue in either Gecko or Gonk and certain types of audio files are able to be seeked better than others.

Or something related to bug 1166758

Comment 7

[No-Jun Park [:njpark]]

[Tracking Requested - why for this release]:
Non-blocking issue, possibly affected by android codec.
