Unfortunatelly, I can't help you with the CS42448 and I don't know how it behaves if you switch from AudioOutputTDM to AudioOutputI2S. Have you used the CS42448 succefully with the Teensy? Maybe with the current stereo usb interface? If yes, then...

Exactly!

When I need to debug a sketch, I like to implement a minimum example that allows me to reproduce the problem. In case of the usb interface, I would use the two very simple examples main_usbInput.ino and main_usbOutput.ino. They rule out that...

Thanks for testing. On the one hand, I’m glad that the USB interface works for all your Macs. On the other hand, it's still a mystery why it’s not working for Weiweiweiwear. I guess we have to wait until somebody can reproduce the problem on...

@electricat Thanks for the tests. @h4yn0nnym0u5e implemented the example sketch with the sgtl5000. Generally, there shouldn’t be any issues if no USB host is connected to the Teensy and I assume this behaviour is specific to the sketch. I’ve...

@electricat Thanks for testing and for the good news! @h4yn0nnym0u5e I can't think of any additional information that would be helpful. We tested stereo and 8-channel audio on @Weiweiweiwear's Mac, using both 16-bit and 24-bit configurations. It...

Thanks a lot for your help, @wll3mx! If you have an SGTL5000, you can run the tests suggested by @h4yn0nnym0u5e . However, if you don’t have an SGTL5000, you can use main_usbInput.cpp instead, as it doesn’t require any additional hardware. To...

I'm not sure if the issue you found is related. One reason that suggests it might not be is that I implemented a mixed version of both the new and old USB audio interfaces. It uses the UAC1 standard from the current T4 implementation, but most of...

Hello everyone, It's been a while, and I just wanted to give a quick update on the status of the multi-channel USB audio interface. The good news: I tested the interface today on my Samsung smartphone (Android 14), and it worked right away...
