Sorry to take so long to get back to you. Work was so busy the last couple of days.
Thanks for the tip about long pressing the OPN Volume button. I did not realise that this would mute the mic, but preserve the volume of the streamer. My audio guy who I spoke to today, said that I need to increase the volume of the tv which is plugged in using the optical cable. This will be a better way to control the volume of streaming without affecting the volume of the mic unless I mute the volume as you suggest of course.
Which is what you have suggested as well. This makes sense.
So I will see if that is the headphones out volume for the tv.
I don’t have an iphone, but the long press mute is fine for me and adjusting the volume of the tv will work brilliantly for me (or volume of the laptop). That way I can have the right mic volume for listening to people in the room and have the streamer louder by using the volume of the tv or laptop vol controls.
I don’t have the issue of the adapter going into standby mode as the laptop and tv volume is fairly high. My problem is that I have to unplug the optical cable to get sound out of the coax. But it’s not a big deal.
I will have the streamer volume set to 80%, mic to default and increase/decrease vol of tv output. Thank you.
