No, this is a new Debian installation with Trinity 14.0.5.

Today I downloaded Alexandre's PCLinuxOS with Trinity 14.0.4, and it has the
same problem on this machine, and also on a different laptop.  They're both
HP, but different models; but both have the same audio hardware:

00:01.1 Audio device: Advanced Micro Devices, Inc. [AMD/ATI] Trinity HDMI
Audio Controller
00:14.2 Audio device: Advanced Micro Devices, Inc. [AMD] FCH Azalia
Controller (rev 01)

It looks like this machine will have to use XFCE instead of Trinity.
