@log4x4 Yes sure. But on the latest macs you don't have a 'normal' USB port anymore. It's all USB-C and you can't connect the EMU directly anymore. Unless I'm missing...

@log4x4 but the idea might be good to avoid any additional electronics. It looks like this one for instance Varta USB-C - USB 57946101401 USB-adapter does not have any additional...

@jakubzwierzycki ok then probably the driver is somehow not finding the connection and therefore the EMU never is registered as audio device (it remains an unknown USB device). For now...

This is a huge amount of work and tricky as well (one error and we have a failing driver). And I can't work on this for long stretches. So I'm...

The plan is to replace also the AD ringbuffer partially with this generic one. I will need to do some performance comparisons before and after replace as I don't have...

In-between CPU load test. Should not make any difference at this point - old ring buffer stil active at this point but we're close to removing I hope HALLab: 1.4%...

Something seems broken badly. HALLab still starts up but Audacity hangs up. Really not sure what's going on, I always test these basic things before pushing. I reverted to last...

I did nothing, just restarted today, rebuilt, install kext, and started Audacity. It now works all fine again??

I re-enabled the pop. Apart from the first "warning. Ignoring overrun", it Audacity runs for 7.5 minutes without any hickup. Tested another time, 3 minutes. Same, works without any issue.

Connected convertFromEMUUSBAudioInputStreamNoWrap with the ring buffer. This time, no problem at all!! Previous 2 times the machine panicked immediately I checked the performance. Notice, at this point the OLD ring...
