Hi Peter, I am running an Asus Pundit-R which also uses the ATI IXP chipset for audio. This runs fine using ALSA 1.0.8 (I downloaded and compiled mine a while back) I see you are using atrpms packages for yours so you should be fine. In order to route *all* sound through the SPDIF you need to set up your ~/.asoundrc file to direct all PCM output to your SPDIF and not your regular line-out. On the ATI IXP, the line-out should be device 0 on the card, and the SPDIF device 1. Therefore, your ~/asoundrc file should look like this: #------------------- start cut here ---------------------- pcm.atiixp { type hw card 0 } ctl.atiixp { type hw card 0 } pcm.!default { type hw card 0 # device 0 ## uncomment this line for analog line-out device 1 ## uncomment this line for SPDIF out } #-------------------- end cut here ---------------------- This allows you to uncomment either device #0 (for analog output) or device #1 (SPDIF, which is what you want) which sets this as the default device for all sound output. Using alsamixer, you will also need to change a couple of IEC958 based settings. To enable SPDIF output, I had to: set IEC958 Playback Switch to TRUE (turn it on) set IEC958 Playback AC97-SPSA to 3 Once this is done and it is working, I'd recommend storing this setup to a state file, so that you can restore this easily in the future: alsactl -f /etc/asound.state.spdif store In MythTV, use ALSA:default for sound output. There are issues if you are using a PVR-350 card and running its decoded audio back into your soundcard and then out of the SPDIF, but all normal audio (live TV, recordings, music etc) should be fine. Let us know how it goes, Nick _______________________________________________ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
