clogged sink

I cannot get my drain auger into this pvp pipe. Is this an air vent? no vent on the roof. In the picture, the pvc pipe goes into the wall is called? under the house, one pipe goes through the floor.

Your picture doesn't work. What size cable are you using?

Thank for answering, I fixed the pictures cause I forgot to upload. I have been using a 1/4" coil snake and 1/4" flat snake. I'm going to buy the 1/2" coil snake. In the picture, the pvc pipe goes into the wall but I don't see a pipe on the roof. I went under the house and I found only one pvc pipe which comes through the floor. Is this pvc pipe in the wall an air vent?

Take the p-trap apart and go down the drain with it. No need to go up the vent. Your 1/4" snake should do the trick

is that upper pvc pipe a vent? I cannot see one on the roof.

It should be. It would have to come out somewhere
