It works just fine for me. AC3/DTS passthrough works for DVDs played by xine (and a couple of HD clips I downloaded, which mythfrontend can be tricked into playing), while PCM audio works for recordings. Sometimes audio & video don't start out synchronized on DVDs, but skipping forward and back one chapter usually cures that for the rest of the show. (I'm using the onboard optical output from an FIC AU13, connected to an input on a Kenwood VR-6060. My MythTV box runs Gentoo Linux, currently configured with Linux 2.6.9 (from the development-sources ebuild, which is 2.6.x without any Gentoo patches). The ALSA driver (snd-intel8x0) is the one provided by the kernel; the other ALSA-related ebuilds currently installed are alsa-utils 1.0.5, alsa-headers 1.0.6a, alsa-lib 1.0.6, and alsa-tools 1.0.3.) _/_ / v \ Scott Alfter (remove the obvious to send mail) (IIGS( http://alfter.us/ Top-posting! \_^_/ rm -rf /bin/laden >What's the most annoying thing on Usenet?
