Re: [PATCH v6 0/1] MR2565: mmdevapi: Implement function 'AEV_SetMasterVolumeLevelScalar'

[Huw Davies (＠huw)]

There's too much going on in this commit / MR.  The changes to the drivers seem to be addressing a bug rather than implementing the Endpoint Volume API.

Also, note that the values passed to the non-`Scalar` API are in decibels, the `Scalar` API appears to be somewhere between linear and logrithmic, and the `ISimpleAudioVolume` values are linear.

Does your app call the `Scalar` versions of the API?  If so, a good start would be to write some tests to figure out the mapping between `Scalar` and non-`Scalar` by e.g. setting using one and retreiving that value using the other.
