If this helps on the sound question, if I switch over to the standard audio out jack, then I get sound as well. Seems like the sound is being routed correctly over the SPDIF

The sound is still not working, but holding my finger next to the optical out on the back of the card shows light, so I suppose that it is working from the point of view of my computer, anyway. My surround sound receiver isn't recognizing the signal unfortunately. I guess the only three possible problems is that the sound is being encoded in a way that the receiver doesn't understand, the light isn't actually carrying any sound and I still have a configuration problem, or the receiver has a broken optical in (which has never been used before, so who knows...). I think (hope) it is probably the second or first one, but I'll keep playing with it. If you have ANY suggestions, I'm pleased to receive them. Also, at first, I thought the clarity of the 1080i (540p in some cases) is actually better than the NTSC output. However, after playing with things, I'm not sure this is the case. Most of the clarity seems to come from simply having such a low resolution (the text is huge). Sure, there is *some* clarity enhancements, but seeing as the resolution is so low, I wonder if it is really worth it. I can crank my resolution up, modulate it to NTSC, and I get more screen real estate, the picture quality (for an average video user) are very close (admittedly, the 1080i/540p is better), but by how much and is it really worth it? What does everyone think? Thanks, Brandon PS. I am piping the video to an HDTV over DVI->HDMI. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Michael Ford Sent: Sunday, July 31, 2005 5:57 PM To: Discussion about mythtv Subject: Re: [mythtv-users] ALSA Sound Create a .asoundrc file with the following and place it into the home directory of the myth user. Then use ALSA:default or ALSA:spdif in Mythtv and Mythmusic. Also, make sure you turn off "Multi Track Rate Locking" if enabled or you will get sound output at the wrong speed. This will effectively output all sound through your optical out so your receiver/processor can do all the work. pcm.!default { type plug slave.pcm "cards.pcm.iec958" } pcm.!spdif { type plug slave.pcm "cards.pcm.iec958" } pcm.!iec958 { type plug slave { pcm "hw:0,1" format S32_LE } } Mike Ford On Sunday 31 July 2005 1:41 pm, Brandon Rogers wrote: > All, > > I know this has probably been talked about before, but since > after 2 days of searching Google and trying "solutions" others have posted, > I will come back and ask a question (which has probably already been asked > 1000 times).
