That's the right way to handle it. Not directly relevant to Amazon, but I had a comparable experience with a different and much less prominent streaming provider. The picture quality was exemplary, but the sound mix was movie-ruiningly atrocious. It had been normalised to the point that during a lull in a conversation, the background sound of chirping crickets would rise in volume to match the volume of the dialogue. I tried several playback devices, it made no difference. I tried reporting the issue, but didn't have the will to wade through their irrelevant questions, so I simply decided to never buy from them again.

Turns out I'm not the only one:
