OK totally confused- this is related to compiler optimisation- it stops working when set to 'debug'.

I definitely pulled the latest versions from GitHub - but I'm only getting results when USBHOST_PRINT_DEBUG is set in USBHost_t36.h . benchtx is reporting about 13Mbit on TCP.

Teensy4 600MHz 1.48 , IDE 1.8.10, compile mode is debug. How do I tell if the version I have has the debug information issue? I assume the version that fixed this was pushed to GitHub?

My mistake- the vendor ID is 0x0B95 not 0x0895 in the source code I have. I read 0x0895 for 0x0B95. I think i need better eyes... However, i definitely can't get it to start up unless debug is enabled in...

VID 0x0b95 PID 0x772b Claims to be an AX88772B The version of TeensyAsixEthernet i pulled from GitHub had VID set to 0x0895 in claim()

Finally got it to work on my AmazonBasics USB adapter- has the vendor ID 0x0b95 rather than 0x0895, though. Gets a DHCP address and is pingable. Also, it only seems to work when USBHOST_PRINT_DEBUG is enabled. No...

Found the origin of the artefacts- I was feeding FreeverbStereo two channels instead of one- that overwrote one of the internal comb filter buffers silently and introduced a periodic noise. However, the original...

Can confirm that MQS works nicely, but there still may be a use for the PDM Filter: the MQS pins are the same as the hardware SPI so unless those can be remapped, this could allow the use of SPI at the same time.

Sorry wasn't aware of MQS or the output_mqs class in the audio library (it's not in the audio design tool). I keep on finding useful things that I wish I knew about! Might still be useful for two-channel output (1...
