Xonar Essence ST (PCI) on 2.6.32-rc8-00011-ga8a8a66: no analog audio, SPDIF fine

Good evening,

After the success of the Xonar D2X in my system, I decided to upgrade to
an Essence ST (of the PCI variety, no D6 daughterboard). Unfortunately
it seems that it produces no audio for me over the headphone port (the
reason I bought this card) or the front-panel headphone port.
I currently lack the RCA cabling to hook up the analog "speakers" port,
but I promise to try this as soon as practical.
The SPDIF output is functional and can be switched on and off using the
mixer controls.

I'm wondering if the Essence ST driver was written based on an a ST+D6
engineering sample as mine is the ST (no D6) retail box. Is it possible
that the hardware is different?

lspci output follows, in the hope that it is of use:
01:06.0 Multimedia audio controller [0401]: C-Media Electronics Inc
CMI8788 [Oxygen HD Audio] [13f6:8788]
	Subsystem: ASUSTeK Computer Inc. Virtuoso 100 (Xonar ST) [1043:835d]
	Flags: bus master, medium devsel, latency 64, IRQ 17
	I/O ports at c800 [size=256]
	Capabilities: [c0] Power Management version 2
	Kernel driver in use: AV200

At any rate, thank you for the oxygen/virtuoso driver. Hopefully this
can be solved. The card does seem to be driven fine as the PCM sinks
receive their audio without complaint and any multimedia player I use
starts output.
