The device that's at the root of the problem is a sound card like device 
the connects a communications radio to a USB port. The controlling 
programme displays the message. As I say, the same programme runs 
perfectly on my Raspberry pi which led me to suspect that the sound 
system of my ageing ThinkPad T420 might be the cause

This is the device that connect the radio to the USB port:

Device: usb 0x29b3 "PCM2903B Audio CODEC"

The CODEC that needs to be used with this device is:

hw: card = CODEC, dev = 0

Selecting this option from a long list causes the error message to be 
displayed on the ThinkPad T420 but not the Raspberry pi.

What do you think?
