No audio input via hi-fi berry, or class compliant USB device #117

I have a Pi 3B and the official touchscreen. I'm using the pre-built image 1.5 (I'm getting a crash when selecting audio sound card on 1.6 and 1.7). I trying to send an analog audio input to the input of the Hi-Fi berry (and the USB device).
The only error I see is a constant error "No AES! Reset" when I go to any of the metering screen.

The only error I see in the logs mentions "SoundcardManager Pi build currently does not support duplex streams" which seems to imply that the audio input and output cannot be used simultaneously, though that is just speculation on my part.

If I go to the output device, and select the Hi-Fi berry, then return to the input device, it appears that the input is disabled, as it is no longer free, though that could be a simple bug with the UI refreshing.

Below is a screen shot of the error messages:

I wanted to add an update here to anyone that encounter this.

I was reproducing the above bug with a Raspberry Pi 3b and HiFiBerry DAC+ ADC, and a class compliant UBS device. I decided to try a spare Raspberry Pi 4 that I had and the problem seemed to go away. So, to anyone that wants to get this working but is encountering similar error, try using a Pi 4.
