Volume control sensitivity is all in ~5px

[Peter Waller]

It seems as though the volume control currently uses a linear scale, which means that in order to have any impact on the perceived volume, I need to move the controls to the bottom ~5 pixels, where a single pixel difference makes a very large change in apparent volume.

It seems linear is sensibel still. Logarithmic seems unintuitive to me - most audio controls are linear imho. What would you expect the scale to be?

[Peter Waller (peter.waller)]

The problem is that it's not perceptually linear. The scale should be linear in decibels, not amplitude, which I believe is the current case.

This means that the controls are almost useless, since you have no fine grained control on the apparent volume - it's all crammed into a few pixels space rather than across the entire control.

Thanks - this was indeed news to me. The link was useful.

Setting to incomplete for bug sweeping.

Yes, we definitely should use one of the logarithmic dB scales.
