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.

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.
