hay, i am a beginner need some help i am working on beamforming project, i have to connect 8 speakers with teensy 4.1, i need guidance how i can connect them wtih controller, teensy 4.1 has only 2 i2s protocol pins.
 
There are two I2S busses, one has 5 data pins, the other has 2. Each has one output pin and one input, but the remaining data pins on SAI1 can be chosen to be output or input. So you can do 8 outputs (each pin is stereo), e.g. using 8 of these.

The Design Tool has a fair amount of connection data in its Info pane, as @MarkT says.
 
Yes, but most other SAI3 pins are only available if you build your own hardware, they’re not on stock Teensy 4.x. Plus you then need to add the low-level code to drive it.

AudioOutputI2SOct will already do the job using SAI1.
