We do lessons online and the problem is that I can't show myself (because the camera broke on my laptop or doesn't work after an update) and secondly that I can't talk because the lessons are so early in the morning and I all people would wake up in the house. We're 6 people in the household (parents have to go to work and I still have 11 and 2 year old siblings who sleep during the time and are right next to my room)
Would it be okay if I was only there and chatting?
Why don't you ask your teacher? We can hardly answer that here. And even with siblings in the next room, nothing should speak against quiet talking.
No. You have to be in attendance like being in conversation
Get a headset with micro. Give it for 20 euro. So you can be pretty quiet and still be understood. ^^
You can also go to the living room or the kitchen, speak quietly with a headset and nobody will hear you
Just take headphones and say only the essentials
I'm present
Not quite, you have to be part of the conversation. You can't prove this in chat
