Hey guys,

This is my first post!

I'd like to know if the ALSA driver for the Asus Xonar Essence ST (PCI) is advanced as the one for the STX (PCI-E) version. According to the ALSA website, the PCI version has had driver support since ALSA 1.0.22 (this is the version of ALSA in Ubuntu 10.04 which I will be using) while the one for the STX (PCI-E version) has been available since ALSA 1.0.20 or kernel 2.6.30. In particular does the ST driver have the features desribed here:

Does the the ST driver have the ability to choose headphone impedance, the ability to switch the DAC from a sharp to slow roll-off, and also alter the oversampling rate from 64x to 128x?

Thanks!
