Strange HD500X behaviour on MacOS 10.15 Catalina

Recommended Posts

The setup:

I'm using the Line6 POD HD500X as an audio interface on my 2017 iMac recording into Logic.

 

The problems:

1) Generally everything is working fine, however, after some time the audio randomly drops out for small periods of time, <1 second, leaving small patches of high pitched digital noises on the tracks if I'm recording. This also happens when I'm not recording, or doing any intense work.

2) Other applications playing sounds, f.ex. finder or safari, exhibits weird behaviour like pausing or skipping to the end of tracks during these randomly audio drops.

3) Most annoyingly, disconnecting the POD HD500X causes all USB and bluetooth peripherals attached to the computer to disconnect (keyboard, trackpad, external drives etc.) forcing me to hard reboot.

 

Any idea whats going on?

Yes although your HD500X is working with Catalina - the Drivers are not compatible. Hence the sketchy audio - drop outs etc...

Huh! The driver download page lists Catalina as supported, and here it states "All currently supported drivers and devices work as expected" but I guess thats not entirely true then. Have they officially dropped support for the device?

Sounds like you need to increase the number of buffers on your PODHD.  Or try a different USB port.  Also try to use a USB 2.0 port also.

I have tried upping the buffer size, connecting through a USB 2.0 hub, tracking without input monitoring and other tracks disabled and neither seems to help. It seems completely random - sometimes I can use it for extended periods of time without issues, but then it starts acting up seemingly out of the blue.

You don't want to use it through a USB hub.  Make sure it's plugged into it's own USB 2.0 port and if that doesn't work try a different UBS 2.0 port.
