Public bug reported:
These cards are picked up as having mute/VolUp/VolDown buttons, but they
only ever report a VolDown. Windows behavior (without manually installed
drivers) appears to match OS-side volume to the display on the card,
which suggests the card tries to report its volume level as an absolute
value. Ubuntu interprets it as turning the volume down (even if the
volume was actually turned up).
My workaround was to remap the "buttons" on the card to "reserved" using
the hwdb and manage OS-side volume with media keys on my actual
keyboard.
