The Chaintech AV-710 soundcard is a 7.1 soundcard which uses this driver. It has two DACs. There's a standard DAC that drives the first six channels. The rear surround channels, however, are driven by a high-quality Wolfson DAC. Audio enthusiasts like to set the card to drive the main two channels through this DAC instead in order to get a very high quality stereo line-level output. The card's Windows driver has an option to do just this, and in the past people have been successful doing it on Linux. I am attaching an asound.state file which owners of this card used with ALSA 1.0.7 to achieve this. However, I am having trouble getting this to work with ALSA 1.0.8. The rear surround output just produces white noise all the time. This is the case both with this asound.state loaded and also with default levels (i.e., what I get if I wipe /etc/asound.state and re-run alsaconf). It'd be nice to know what changed between 1.0.7 and 1.0.8 that caused this to break, and how to fix it. Thanks! ====================================================================== ---------------------------------------------------------------------- jaanusk_ - 05-24-05 21:35 ---------------------------------------------------------------------- Seems so, at least all av710-s seem to be detected as audio2000-s.
