I was in this boat not too long ago. After posting a similar<br>question here, I ended up doing the following:<br><br>1. I bought a Turtle Beach Riviera card for the Dolby Digital<br>out. This has stable Linux support (the snd_cmipci ALSA driver
<br>handles it), and it comes with a SPDIF optical output. I assume<br>there's something out there that could convert this into a<br>coaxial output if you needed it. The card costs only $30 and<br>requires a conventional PCI slot.
<br><br>2. Use MythDora 4.0 to set up a clean Myth installation if you<br>can. In the process of trying to get Dolby Digital working first<br>using my motherboard's built-in audio and second using a Sound<br>Blaster Audigy 4 (I later found out Linux doesn't support this
<br>function on this card so now I've got to sell it on eBay), I must<br>have fouled up the ALSA configuration to the point where it just<br>wouldn't send the Dolby Digital through the Turtle Beach card no<br>matter what I did. At least with MythDora, it had a known good
<br>mix of packages.<br><br>Since doing these two things, I have Dolby Digital and DTS<br>pass-through working fine. I had to change a setting in alsamixer<br>to activate the SPDIF output port on the card and change a few of
<br>the audio settings in the frontend setup, but there was no<br>fiddling beyond that. I get the Dolby 5.1 audio on HDTV<br>programming, and Dolby/DTS soundtracks play back fine from DVD's.<br>But in my case, I was fortunate that I did this before I had gone
<br>too far with building up a library of recordings, videos, and<br>other stuff.<br><br>-----Original Message-----<br>From: <a href="mailto:mythtv-users-bounces@mythtv.org">mythtv-users-bounces@mythtv.org</a><br>[mailto:

</a><br>Subject: [mythtv-users] Ready to try for Dolby Digital again....<br><br>OK, I gave up over a year ago but I think I am ready to try<br>again....<br><br>I want Dolby Digital output from MythVideo/Xine. Is that too
<br>much to<br>ask for? I fought with it for days a year ago and eventually<br>gave up.<br><br>I'll buy whatever card it takes to make it work. Does anyone<br>have a<br>configuration that will make it work?<br><br>Right now I have a Chaintech AV-710 audio card and I have managed
<br>to get<br>digital audio output, but cannot get it to work with anything but<br><br>2-speaker output. Things I have tried have led to either no<br>sound<br>output or an error message saying that the device is not<br>ready/available.
<br><br>I am currently using the latest MythBuntu release, so things<br>should be<br>fairly up to date.<br><br>Anyone got a prebuilt solution?<br><br>Also, while I love MythVideo and really appreciate the work done<br>there,
<br>I have to ask why they limit each movie to 1 genre? It makes it<br>hard to<br>categorize my movies (comedy thrillers, etc). With over 300<br>movies<br>online it is cumbersome to always resort to alphabetical<br>viewing...
<br><br>Thanks a ton,<br><br>Craig L.</blockquote><div><br>I'm also using a Turtle Beach Riviera. I had it working back with version 0.17, but I had to do tweaking with .asoundrc files and such. I went the MythDora
4.0 route when I upgraded recently, and it was exactly as Greg described. I set a few frontend settings in the mythtv general menu, un-muted iec958 in alsamixer, and that's it. Works right out of the box.<br><br>-darren
