jdufault@ any thoughts on who best to route this to?

skonig@ likely knows someone

Vadim, can you take a look?

This doesn't reproduce for me on Mac or Linux.  Is this a Chrome OS specific issue?

David - could you please try to reproduce on a few platform including Chrome OS?

On CrOS 53.0.2785.55 dev with the same site as reported, I sometimes see the volume jump (increase) past the current mouse location. However, it's not always at 85% (more like 10% increase wherever the cursor is) and not 100% repro-able.

I haven't tried to repro on other platforms.

I'll show David when he gets in.

Hi Sarah, attached is a video of what Jennifer and I are seeing here. Does that look similar to what you are seeing? We aren't able to repro a large jump to near max volume every time like you described though. Could you see if it still occurs after updating to the latest Chrome?

Thanks!

Note that to view the video you'll need to download it and play it locally. Not sure why it's all white in the player above.

Interesting -- I wonder if something recently fixed this.  

In this env:
Google Chrome	54.0.2830.0 (Official Build) dev (64-bit)
Platform	8714.1.0 (Official Build) dev-channel samus
I'm no longer seeing this behavior. 

Regarding the video in #10, what I was seeing was that jump was up to ~85% consistently, but now I'm not seeing it.  I saw the bad behavior on multiple builds.  I'll try to do further testing over the weekend when I'll have more time to cast music from CrOS.  Thanks!

Hey Jennifer, the issue we observed was really minor. Should we look into it? If not, I think we can close this issue as no repro until it happens again.

Per offline discussion:
We'll keep this crbug open as it does repro (just not to max volume). dbbrooks will monitor the behavior during his test runs.

+o vadimgo for investigation/further triage as this is relevant to the custom controls.

For what it is worth, I'm not really seeing this issue recently.  Not sure if something fixed it for everyone, but it looks better on the following for me:

Google Chrome	55.0.2878.0 (Official Build) dev (64-bit)
Platform	8861.0.0 (Official Build) dev-channel samus

Should we just close it?  

This issue has been Available for over a year. If it's no longer important or seems unlikely to be fixed, please consider closing it out. If it is important, please re-triage the issue.

Sorry for the inconvenience if the bug really should have been left as Available. If you change it back, also remove the "Hotlist-Recharge-Cold" label.

David, do you mind trying to repro this again now that native media controls have shipped?

Cast implements some "rubber banding" to prevent large jumps in volume that might damage hearing or speakers.  But I would expect that to result in a smaller net volume increase, not a larger one.

I haven't been able to repro this. (on M61, 62, 63)
