Audio & Other Issues

Time and time again my teammates would say they "Cannot hear me", and I have to slide the outgoing audio bar in the settings to fix it... barely. This audio setting allows for people to prevent a whole lot of background noises from occurring. Kinda hard for it to work when no matter what, you can't hear the other person very well. On top of that - footsteps are still buggy. People go quiet from time to time.

Another thing is, is there SBMM? I could of sworn someone said there was, but what doesn't make sense is that I keep getting potato teammates and I know others do as well. On top of that, the account levels seem a bit fishy to be put in the same match. Sure, low levels could be smurfs/pros, but it honestly feels like hackers are still being allowed to bypass the system ban. I get that's hard as well, but why is it such a big issue?

Here are a few pictures of different players who's skills may not reflect their banners, but the thing is that there's a lot of low level players. I didn't get a picture of this because it went away when I noticed, but one game had a champion team of players below level 15. (a level 7, 12, and 9). How are low level players champions? Are they favored for being new? Further more, how are there level 10-30 players in ranked Gold and higher?
