Hi Paul,
OK, http://smedley.id.au/tmp/uniaud32-linux-4.14.202-20201121.zip doesn't trap (or produce sound) on my X250, T60 or virtualbox systems...
Small change in hardware here, I went from my MSI 880G-E45 motherboard to a MSI 890FXA-HD70. The advertised specs showed a RealTek chipset:
1) 880G-E45 => RealtekĀ® ALC888S/ACL889
2) 890FXA-GD70 => RealtekĀ® ALC889

...was now trapping on the newer 890FXA-GD70 board.
Anyways, the good news is that this latest drop does NOT trap, but as others have noted, it does not produce output either.
For me it's a positive direction given no TRAP! Thank you!
