I have moved your question here, please see the first and second posts to find suggestions.
Note: you might run Fedora 34, but the Remote Exam runs from the live usb environment and loads it's own Linux system (I think it's based on Fedora 33 at the moment).
The laptop's inbuilt mic is not working in Live OS. So I ran the compatibility test using wired earphones. Finally, the compatibility test is succeeded in Live OS.
Can we use wired earphones in the examination?
Hi,refer to this document for more information:
From my experience a wired earphone was not allowed. I had the headset + microphone on the desk and the proctor asked me to discard it.
Your webcam microphone mic will be used I think, since you require an external camera...
Look carefully in the doc above there are some steps about the microphone test not working. You can also live chat with the support, from the Remote Exam compatibility test, to discuss that particular matter.
I have an upcoming remote exam and was running the compatibility check. I noticed that my external webcam was recording the mirror image of myself in front of my monitor. I experimented with showing my ID document to the webcam and it displayed the reverse image. In other words the printing looked backwards, like in a mirror. will this be a problem? there doesn't seem to be any controls in the compatibility setup that let you adjust anything about the camera and there are no buttons or controls on the webcam that allow you to do anything.
I have other webcams and they all do the same thing. they show your mirror image. Like its looking at you from a mirror. so printing appears backwards, like a mirror image. I'm surprised NOBODY has ever mentioned this. Was this a problem for the exam Anybody?
That's normal, and the viewer will see you and the ID properly.
It's quite common for webcams to show you "horizontally flipped", to be easier for you to see, and the remote viewers see normally (not horizontally flipped).
I use Logitech C930 and on the webcam preview my ID shows mirrored, but it was accepted every time, I sat 4 exams with it. Only, it took a long time for the proctor to verify my ID.
The C270 is listed in the not recommended section, I guess because lack of autofocus, see https://learn.redhat.com/t5/General/RedHat-Remote-Exam-supported-hardware-cameras-mice-keyboards/m-p.... See also the list of supported models, maybe you can get one of them.
