Using Teensy 3.2 on ethernet with VBAN Audio
VBAN Ethernet on Teensy 3.2 We need some modifications on the internal library's in ethernet.h uncomment #define ETHERNET_LARGE_BUFFERS change #define MAX_SOCK_NUM 8 to #define MAX_SOCK_NUM 2
in w5100.h change the SPI speed to fastest e.a. #define SPI_ETHERNET_SETTINGS SPISettings(30000000, MSBFIRST, SPI_MODE0)
Select Audio in USB > Type or Audio+Serial+Midi~, I'm using CPU on 144mhz but should work aslow as stock mhz.
I'm'not using the audioshield however it could work anyway with it. but you need to integrate the SGTL code stuff. Curently Im using a PCM5102A
Second, when connected through USB to a PC, it can also be used as a soundcard, but only on 44100hz! In VBAN it's possible to change samplerate up to 96khz (some are not listed) doing this will break USB sound, resulting high/low crackling pitch playback.
Pinouts
| Teensy pin | DAC pin |
|---|---|
| 23 | LRCK |
| 22 | DIN |
| 9 | BCK |
| 11 | SCK |
Ethernet shield W5200/W5500 (W5100 is too slow! will lose packages)
| teensy pin | eth |
|---|---|
| 12 | MISO |
| 14 | SCLK |
| 7 | MOSI |
| 6 | SCS |
| 5 | RST |
There is some glitches aka, a 40ms silence randomly. I don't know where this come from. but less then using Wifi on the ESP modules.

Get the VoiceMeeter Banana application on https://www.vb-audio.com/Voicemeeter/
And follow some other tutorial to get it working first.
When you done that, go to the VBAN window, enable VBAN and add the IP from the teensy in the output section.
as for this sketch it works with the follow setting in green.
