I've run into the same problem with the same combination of chipset and codec, only on an Abit KN8. With an optical S/PDIF connection to my receiver (a Kenwood VR-6060, if it matters), I get occasional dropouts. For SD content recorded by one of my PVR-x50s, it's a half-second to one second. For SD and HD content recorded from my cable box, the glitch causes the receiver to switch out of AC3 mode and back (it's very noticeable, with relays clicking back and forth). You can lose two or more seconds of audio this way. You can replay what you missed by winding back and replaying it, but it was a major annoyance. > whats the problem your having?

Reusing the .asoundrc I had on the old system didn't work. I eventually got PCM and AC3 audio working, but with the glitches described above. I brought home a USB audio adapter today. It's a Siig US2331, identified more prominently on the box as the "USB SoundWave Optical 5.1." It has a USB port on one side and 2-channel analog and optical S/PDIF outputs on the other side. With the usb-audio driver in the current stable version of ALSA (probably in some older versions, too), it Just Works. I played an HD recording of this week's E-Ring through it and had no audio glitches at all. I haven't tried it yet with xine or mplayer (mainly because they're not installed on my new Mythbox yet), but if MythTV can send both decoded PCM data and AC3 pass-through data through it, those other apps should work as well. It was about $40 at Fry's, and since it's USB, it doesn't need a slot. (The three PCI slots on this board hold a PVR-350, a PVR-250, and a FireWire card.) With PCI slots disappearing from new motherboards in favor of PCI Express slots that hold mostly-vaporware PCI Express add-on cards, a USB-to-S/PDIF converter such as this might be a better fit for a MythTV box than a PCI soundcard. _/_ / v \ Scott Alfter (IIGS( http://alfter.us/ Top-posting! \_^_/ rm -rf /bin/laden >What's the most annoying thing on Usenet?
