How does it make sense to have this all day call
Open offices have a lot of problems, but they proliferate.
In a lot of companies, it is far more important to prove that activity is occurring rather than to actually achieve anything. I had a boss who openly acknowledged that at least part of my value as an intern was as "activity furniture" to help non-technicals think that something is being done while many people were on summer vacation.
In another internship, the order came down from above for everyone in the department to be in the office for this several hour period and be doing something visibly productive (whiteboard, meetings, etc). oriented towards the hallway so that you were easily spotted in the breakout rooms. For those hours, I was a decoration to make some other higher up seem impressed.
In both cases, the fact that people had to cancel meetings or teams had to cancel sales or were just making up work on the whiteboards to look active was irrelevant. I bet that the equivalent of two weeks of manhours was thrown away for that. I suspect that is what you are at the moment.
Half your value is in being a developer and half as activity furniture.
Many companies do not meaningfully evaluate productivity either, so they effectively do not care about destroying it in many cases.
I would just turn down the volume to what it would be if I were in the office and if I really needed to work, I would just mute it and claim "technical issues."
