The card in this system is a Creative Sound Blaster Audigy FX (PCIe 1x).
Outputs on the back are: Line In, Microphone In, Front Out/Headphone
Out, Rear Out and Center/Subwoofer.
The other system has a Creative Sound Blaster Live! 5.1 (legacy PCI).
Per the user guide, it has: Digital Out, Front Line Out, Rear Line Out,
Microphone and Headphone.
The jacks on both cards are all 3.5mm, the headphones are USB.
Test results: same on both, volume does not change on either system when
the inline volume control is used.
One difference on the other system (with the Creative SB Live! card) is
that when the volume progress window appears, the white bar as described
previously, is dark blue on this system and only advances once,
regardless of how many times the + on the switch is pressed.
On both systems when using these headphones, the Kmix icon in the TDE
panel shows the volume at 0%.
I would guess, then, that Logitech has helpfully installed an incompatible
'improvement'
to your headphones' built-in firmware. I know that their mice, whose basic (3
buttons,
scroll wheel) features work fine in Linux, have additional features that Linux isn't
able
to take advantage of because Logitech doesn't release details of those features'
APIs.
