[SOLVED] Audio glitching on Pi 5

Hi @DRONE7. Ok, here's the output:

Excellent!
Have you got a powered USB hub that you can install between your Pi5 and the Audiolab DAC ?

There may be a usb issue re the TI usb hardware and the Pi5 USB. (vs the Zero2W)

Raspberry Pi 5

Raspberry Pi 5 has two USB2 ports and two USB3 ports (total 4). These ports are connected to 4 distinct USB hubs 1,2,3,4 in really weird configuration. If USB3 device is connected to blue socket, it will be detected on USB3 hub 2 or 4. If USB2 device is connected to any socket or USB3 device connected to black socket, it will be detected on USB2 hub 1 or 3. Regardless of USB2/USB3 connection type, blue sockets are always port 1, and black sockets are always port 2.

Each of 4 USB onboard hubs advertises as supporting per-port power switching, but this is not true. In reality, Raspberry Pi 5 all 4 ports are ganged together in one group, despite belonging to 4 different logical USB hubs.
