roommate issues

At the beginning of the year, I had no issues with my roommate, but a couple weeks ago, that changed. A couple weeks ago, my roommate started to skype people loudly very late at night, he usually talks to his friends while gaming, and frequently talks until 2 AM. I wake up at 8 AM on most weekdays, and I hence his calls are very disruptive, I have tried to communicate with him when he is calling, but he didn’t hear me, and I had to write a note and slip it onto his keyboard in order to get his attention (the call ended immediately after that). Two nights later, my roommate was skyping once again, and this time I told my RA about the issue, and she also requested that he go outside to finish his call. Despite getting his attention over the issue, he still does it nearly every night, and at this point I don’t know what to do, has anyone else had a similar issue?

request for a room change. That’s the best you can do.
