Sorry, I haven't read the entire thread very carefully, but I understood that the issue is with the usb-audio only and independent from what DAC is connected or used. My use case: I am building a 'groove box' (synthesizer, drumcomputer and sequencer in one box). It has 6 tracks. Usually one is...

Hi, I don't really know what the CS42448 is. A DAC chip? My test setup was: - Teensy 4.1. connected to teensy audio board via I2S - Teensy connected to Mac via USB - Select teensy MIDI/Audio as audio interface in DAW (Reaper) - receiving audio from the teensy in an audio track on the DAW, and...

These are the machines I tried: - MacBook Air, Mac15,13, MRYR3SM/A , MacOS 15.3 (audio in both direction works) - MacBook Pro, MacBookPro13, (no model number), MacOS 10.14 (audio in both direction works) - MacBook Pro, Mac14,7, Z16U000RFSM/A, MacOS 15.3 (only tested audio from teensy to Mac on 2...

Ok, I tried again on the 4 Macs in the house, and this time everything seems to work fine (Had to remove the infinite serial wait). I could receive audio on all machines. On 2 machines with a DAW installed, I could verify that all 8 audio channels are received, and I could send audio to the...

A, I see the sketch is waiting for Serial in an infinite loop, I guess that explains why it doesn't work on any system that does not have the Arduino IDE running! This if course would change all the conclusions I made. Will have to do the testing again then...

On 2 out of 3 Macs I tried I don't have a DAW installed. I just went to the 'Audio' panel in the system settings, and checked if the teensy appears and if I get a signal. So far I only looked at the output from the teensy as the audio input into the Mac, not the other way around. I used the...

I tried some more, and it looks like this is quite hard to debug. I settled on the minimal testing setup, where I just go to the audio settings page on the mac and check if I get a signal at all. This will only get 2 channels at most I think but still shows if it is fundamentally broken. As...

I am on a Mac and I have been wanting to try this for a long time. The caveat is that I am on quite an old System (Mojave) with Intel Mac. I am now trying it on this system, but I can potentially also give it a go on a newer laptop, just so we get a better understanding if the issues that you...

Here's a sound snipped where you can clearly hear the problem. https://on.soundcloud.com/Whddy Any idea how to fix this? It seems to get worse the more frequently I read midi from USB. Do usb midi and usb audio interfer?

Hi, I am working on a synth project on the Teensy4.1. I am using the audio board, and (in particular during development) audio output via USB. The latter started to produce strong audio artefacts, while analog out is clean. It sounds a bit as if the cpu can't keep up calculating the audio buffer...

Hi, I am getting started with my first synth project on a Teensy. I have some existing code I would like to port, and I'd rather not refactor everything to use the Audio Library with its method of wiring the Audio Objects etc. So my current plan is to wrap my entire synth engine in a single...
