Are you using Gnome with pulseaudio? If you are not sure then post the
output of:
dpkg -l \*pulse\* | awk '/^ii/{print $1,$2,$3}'

It seems that your two internal audio devices are not supported by
Squeeze's kernel (unless you took active measures to prohibit loading of
the corresponding kernel modules); this explains why you do not hear
anything when you use standard headphones plugged into the 3.5mm TRS
socket.
How do you want to proceed? Try to get the Azalia device working or
focus on the plantronics USB headset?
If you are content using the USB headset then my guess would be that you
have to ensure it is recognized as ALSA card number 0. The most common
cause of problems like yours - some applications play sound just fine
while others fail - is that the problematic applications are not
flexible enough to handle systems which have no card 0 or on which card
0 is broken.
The quickest way to check if this is your problem is to unplug the USB
headset and then run as root:
modprobe -r snd_usb_audio
modprobe snd_usb_audio index=0
Then plug in the headset again, verify that it is card 0 now (cat
/proc/asound/cards should show " 0 [DSP ]: USB-Audio ...") and try if
Gnash and VLC work.
