Hi Paul.
I'm sorry to bother you but I think the mic input have lost it's functionality in 1.52 Beta #2.
hardware Teensy 4 + Teensy Audio adapter Rev D

I have it tested with a simple script using a clean Arduino 1.8.12 + Teensyduino 1.52 Beta #1 install vs Arduino 1.8.12 + Teensyduino 1.52 Beta #2.
With Beta #2 there is no input signal from mic and some times there is clock & data lines noise mixed with the audio.

Code: 
#include <Audio.h>
#include <Wire.h>
#include <SPI.h>
#include <SD.h>
#include <SerialFlash.h>

AudioInputI2S            mic1; //xy=454,353
AudioOutputUSB           usboutput1; //xy=727,411
AudioOutputI2S           spk1; //xy=738,357
AudioConnection          patchCord1(mic1, 0, spk1, 0);
AudioConnection          patchCord2(mic1, 0, spk1, 1);
AudioConnection          patchCord3(mic1, 0, usboutput1, 0);
AudioConnection          patchCord4(mic1, 0, usboutput1, 1);
AudioControlSGTL5000     audioShield; //xy=669,235

void setup() {
  AudioMemory(16);
  audioShield.enable();
  audioShield.volume(0.6f);
  audioShield.inputSelect(AUDIO_INPUT_MIC);
  audioShield.micGain(33);
}

void loop() {
}

I have connected a ILI9341 on alternate SPI pins and the full setup (sort of usb audio card image below) was working flawlessly since the first commit with usb audio suport you make to the cores git till this Beta #2

Thanks for all your magnificent work.
 
Hi!

I'm still getting clicks and discontinuities with the USB Audio In/Out after around 20 seconds or so. Same results on both macOS 10.12 and iOS 12.

I wonder if anybody has similar problems and/or suggestions on how to fix it? Looks like it's sending a bunch of zeros:

I'd post the source code, but it's more or less copied straight from the Audio Design Tool. InputI2S -> OutputUSB and vice versa. Audio passthrough via I2S works without any issues.

Prior post in Beta 1 - had a detail or two : Teensyduino-1-52-Beta-1

Note: "more or less copied" - is not a sketch for repro Paul could open - connect - run - and see the problem. Feel free to post exact code - with needed hardware connects parts ( Teensy x.x? and Audio board rev 'letter' ) and connects - that would Copy&Paste to the IDE and demo the issue.

Unfortunately I don't have an Audio Board here. I'm using a custom board with a CS4272 and edited AudioControlCS4272.h to configure the codec as Slave. However, I didn't think that this could cause the problem, since the I2S In/Out itself works without any issues. Sorry for the confusion!

Anyway, the problem also appears when routing AudioSynthWaveformSine to the USB output and monitoring through the built-in speakers of my mac, like this for example:

Code: 
#include <Audio.h>
#include <Wire.h>
#include <SPI.h>
#include <SD.h>
#include <SerialFlash.h>

// GUItool: begin automatically generated code
AudioSynthWaveformSine   sine1;          //xy=151,269
AudioOutputUSB           usb2;           //xy=382,258
AudioOutputI2S           i2s1;           //xy=410,142
AudioConnection          patchCord1(sine1, 0, usb2, 0);
AudioConnection          patchCord2(sine1, 0, usb2, 1);
// GUItool: end automatically generated code

void setup() {
  AudioMemory(20);
  sine1.frequency(440);
  sine1.amplitude(0.8);
}

void loop() {
  while(1);
}

Teensy 4.0
The I2S codec is AK4556VT on I2S1.
The S/PDIF output is just a LED on pin2.
With the original input_i2s.cpp, the input of sound soes not work.
then I replaced that with the one from post #5
. The I2S input test works partially, but during compile throws this output:
Code:

Opening Teensy Loader...

Sketch uses 32960 bytes (1%) of program storage space. Maximum is 2031616 bytes.
Global variables use 53940 bytes (10%) of dynamic memory, leaving 470348 bytes for local variables. Maximum is 524288 bytes.
As said, I2S input works partially. It shows high distortion, as if not every sample is read.
Also, the I2S output has now or then a very short dropout, or short episodes of slight distortion, while the S/PDIF plays clear signal.
I've checked the signals to the chip. They are very clear and rectangular, using in-line resistors, but have quite sime timing jitter.
pin23 MCLK seems to have the same jitter. It looks like there is something not stable with the frequencies/PLLs. The phases do not show constant lengths.

The settings of the AKM are classic I2S. normal speed, proven many times on other I2S devices:
Mode 5, CKS3=L, CKS2=H, CKS1=L, CKS0=H, I2S slave
De-emphasis off, DEM1=L, DEM0=H

So this should be pretty standard.

Other issue: Sometimes, without making sense why, the Teensy 4 crashes during upload. It can then only be recovered by pressing the buttin for 15 seconds until the redt blips, then after a while, there is the orange blink. Closing Teensyduino/Arduino and the loader. disconnecting from USB, reconnecting and repating compile and program works.
There seems to be no other way to recover the Teensy, because once it crashes during an upload, it remains so even if disconnected and reconneced or the Teensyduino and loader closed or reboot PC.
Looks like the Teensy is then pretty much messed, so the long button press is the only way back to work.
This happens on PC amd also on laptop, Windows 10 x64, also different USB cables, all tried.

forgot: When Teensy crashes, the loader shows something like "Erase Error" in red after a while
 
@Deleted User - have not seen that before? "Erase Error" or other upload fails as described. That seems to suggest a failure of the storage EEPROM - or other damage preventing full function.

The TeensyLoader program offers 'Verbose info' under the Help menu item.

With the sketch ready to upload { a Verify build in the IDE } open the verbose info and clear the Log perhaps.

Then try the upload { a button press after Verify } and if it fails then save that log info and upload the file for Paul's review.

If it works to upload repeat the log clear and retry so any events or feedback going along with the 'Erase Error' are captured in whatever detail is exposed.
 
The error happens not always. Today it was 2 times on the one Teensy 4 that is left here.
This one has maybe 50 uploads on the flash, never used something like eeprom library, so the memory should be ok.
Also it has never been exposed to radiation, temperature, moisture or magnetic fields other than natural home ambient.
Never used any power supply other than USB, never connected anything other than the AKM, the LED, and a perfectly working SPI ST7789 1.3'' display, all on 3.3V, so there should be everything ok with that aspect.
The supply and the 3.3V looks clean, but further more I did not scope into the Teensy 4, like crystals or so, because it is too tiny to probe by hand and the test rig is in our lab, not here.
 
Interesting - that sounds uncalled for :( Leaving the Verbose open and hitting Clear before each Upload will capture the transfer messages. If it fails then SAVE the log file and post it to get whatever is recorded so Paul can see it.
 
I've never had this too, even with a hundrets of uploads.
Damaged USB cable? A weird ground-loop? Something is very strange with your setup, because I2S works perfect for me, too. Even with 256k Samplerate (PCM1808 + 5104)
 
@defragster
Yesterday I had the issue several times. Today twice. Since I've read your post I did several uploads to provoke the error, but no problem. The next time I'll post the log here.

No ground loop, just the USB cable, nothing else connected to AKM, the first time the error came. So I changed the USB cable. The next time I changed the computer. Once connected amp to AKM, once nothing, because working on display. Usually I disconnect the audio line before flashing, anyway, so how could be the gound loop? During run no problem shows, also no ground loop noise if connected to amp.
You can be harsh to me, but I keep calm.
Maybe this one Teensy 4 has broken/faulty crystal. That would also explain issues with I2S signals.
 
Paul - Time setting to T_4.0 SRTC is not done in TD 1.52b2 :: See post or two above this one :: TimeTeensy3-example-gt-Time-chosen-is-not-permanent

Also noted in that post - whenever TeensyLoader runs from THIS PC the time showing on the Teensy is 'BACK' one hour!

Using the code in that linked thread the time can manually be advanced one hour to make it match PC time, Then on new UPLOAD the time is Always set back one hour again.

Here is the code in use calling suggested code to set SRTC time on T_4.0 from sketch with renamed function:: Rrtc_set()

Guys, can someone give me a quick. What is teesnyduino explanation?

Is it a replacement for the IDE? Do I still need the original Arduino IDE? From my ignorant user's point of view, everything has changed and I haven't been able to find an explanation as to what I have here.

Thanks!

Teensydunio is an addition to the original Ardunio IDE. You first install the Arduino IDE (1.8.12 being the current release), and then run the Teensydunio program, and it modifies your Arduino IDE to have Teensy support.
