    Hello,

    Thanks for the report. We haven't seen this issue during testing but I will ask the QA/Dev team to investigate.

    Do you have Loudness Normalization enabled in doubleTwist Settings? Does this behavior change if you toggle this option

    Hi again,

    Well, of course I'd figure it out myself, right after posting here. Sorry about that. I've been trying to debug this for months, but couldn't figure anything out until yesterday.

    I found a setting in my phone that I didn't know I had. It's a Galaxy S9+, and the setting is found at (Translated names) Settings -> Sounds & Vibration -> Advanced Sound Settings -> Sound Quality and Effects.

    Here you will find settings for Dolby Atmos. Dolby Atmos as a whole can be switched on/off. After switching it off, the music plays normally, no fluctuations in volume. So it must have been Dolby Atmos interfering, trying to "improve" my experience.

    Some other random facts, in case other people come looking:

    My phone is a Samsung Galaxy S9+, Exynos, and the issue was persistent across Android Oreo and Pie, likely because it's a feature rather than a bug.
    The issue was the same, regardless of the version of Andoid Auto (I have had pretty much all versions from 3.0.x to 4.4.x)
    The car is a Peugeot 208, although I don't know if the head unit has a model number on its own. Tried available settings in the head unit, made no difference.

    Hello,

    Thanks for the update. I will forward to the QA/Dev team so they can look into if it's some type of odd interaction with the Atmos enhancement.

    Hello Morten

    Look into your settings - have you probably enabled the feature "normalise loudness in the "Playback" category of the player itself (I'm not sure if the term is right, I use the German version)? If this is enabled, it raises the loudness if there are "quiet" parts in songs, like the flat part in Trance tracks.

    I hope it is possible to understand what I mean :)

    Best regards from Germany, Biggi
