I wanted to try the Trinity Debian image on my other

the system sounds work, if I installed (into RAM) Firefox and went to
multimedia web sites (YouTube, audio test sites, etc), there is no
audio.
The 'lspci -v' command is showing two audio devices:

The Trinity PCLinuxOS image is installed on this desktop's hard drive
and audio works everywhere. KMix lists three mixers, PulseAudio
(the default), HDA NVidia and HDA ATI HDMI.
The AMD entry is actually a PCI-E x16 video card, with VGA, HDMI and
DVI inputs. It's connected to a monitor via HDMI, but the monitor
does not have built-in speakers. The NVIDIA entry is the on-board
audio.
I tried restarting the audio system by checking then un-checking
a box, but on the Debian image, this didn't correct the lack of
audio. Is the Debian software possibly not recognizing the audio
setup correctly, even though the system sounds work?
Thanks in advance.
BIG typos here, my apologies. :(
Please replace Debian with Ubuntu in the above e-mail.
