Wroom2 multi channel

I have a question was hoping someone could help with. I have a 32 mb version of esp32-s3 wroom2 . I am trying to set it up for 4 channel led outputs. I have tested the output pins individually along with the led strips. Everything works correctly on their own. However, if I enable 4 channels at run time, only the first 2 channels work. Have the current limiter set to 15000ma. My led length is 53. It doesn’t matter the order of the pins, always the same, just the first 2 work. Currently testing on gpio’s 21, 45, 44, 42 . I understand that wled supports up to 12 channels, but using parallel I2s. Haven’t seen an explanation of how that works either. I have had 4 channels working on earlier builds of wled with multiple chip sets and displays, so I am not sure what is wrong. This new code base is a bit different to me and things don’t work like they used to.

what version of WLED?

I am using version 0.15.3 but all recent versions seem to behave the same way.

Try nightly build, it may have better support for S3

ok, will give that a try. not sure why it was working before, but not now. had this working on lilygo t display , Espressif and generic chips with no problems. now everything seems to have changed.
