No Clarinet progress since starting 5 months ago, need advice.

Hello fellow clarinet players,

I picked up a b flat clarinet about 5 months ago, maybe even more, and have basically made zero progress this entire time. I have no money for lessons (am just barely able to rent my Buffet Crampon E12F clarinet,) and thought online resources would be enough to learn, but unfortunately they are not proving very helpful aside from the fingering charts.

The main issue is that basically every embouchure video says something different from the previous, meaning the thing I was just taught is immediately denounced as wrong by the next person. As such, it seems I have to figure out what works well on my own, but the issue is that I am having no success doing so. For starters, I have no idea how much pressure my bottom lip is supposed to place on the bottom of the reed (videos never cover this in detail) and no matter how I do it, my tone seems to still be spitty and airy, and my consistency in actually sounding a note above the break without delay or a forced quiet to loud dynamic shift is also far from ideal.

Right now I am trying to form an embouchure based on this players tips, but he just does not go into enough detail for me to know what to do. Before then I tried to follow this lady's tips on embouchure, but I was not having success and the guy I linked above seems to disapprove of this method. Before then I tried an embouchure based on what was suggested in videos by Fabian Hügli, but found little success there as well. What he says is also opposite to what the two previous players had to say. Before then I was trying to form one based on tips from quickstart clarinet, but it was the same story there.

My entire practice sessions consist of me trying to figure out a good embouchure that gives a good tone without spit and air while also sounding all notes cleanly and clearly. I also try to optimize my air flow to be fast and narrow while doing so. This takes up my entire practice time and always ends in failure, which is why I truly mean that no progress has been made in 5 months. I have not worked on a single piece and only tackled like 2 scales, since I see getting my embouchure and tone figured out as priority number one before I can do anything else.

In case it is useful, I use the generic mouth piece that comes with the E12F, but I don't think that has anything to do with my problems, since I sounded the same on a clarinet in A I used for a very short time, and that had a high quality mouth piece on it. It really seems like my embouchure is just terrible. Another useful bit of information is that I have tried reed strengths from 1-2.5 but have not noticed any difference between, to be honest not even much of a difference in how much air is needed.

The clarinet really does seem to be my kryptonite, as in these 5 months I have been making steady progress with various other instruments that I am also learning. It is only the clarinet with which I have hit a wall that I seem unable to pass. It is really quite unfortunate, as this instrument is amazing. Therefore I would really appreciate some advice as to what I can do to fix this situation and finally actually make some progress.
