Marking a ticket as SOLVED just because they don’t require more information is straight up cheating the ticket system. Sounds to me like support staff are gaming the ticket statistics to impress corporate management.
In this particular situation I believe the streamer mode is working as deliberately designed. It’s not a bug. The devs intend that the user must activate streamer mode every time they start the game. Same as that the audio sliders only go down to 1 (not zero). They want to force the music upon you. I’m sure that the streamer mode option was only created because they could make it temporary (while saving the audio sliders positions) . Otherwise they would have just let us turn the music audio slider to zero. It’s pretty clear the devs discussed and then designed the audio system deliberately to make us listen to the music. Look at the way the radio works. You can turn it to off, but start a story mode, and it is automatically put on a specific playlist, you need need to wait until the game gives you control of the radio to turn it off again. I’m going to guess that it’s a design choice to please the publishing houses of the musical talent.
