Hi to everyone!<br><br>My MythTV used to work flawlessly with a stereo analog sound (2ch). I<br>decided to switch to SPDIF and now when I try to watch TV, DVDs or<br>listen to music (using the Internal player) I don't get any sound.
<br>However, I can watch videos (using MPlayer) without any problem.<br><br>===================================================================================<br><br>I tried fixing the problem, using the following articles:

</a>><br><br>- I get no sound from MythTV when watching TV but MythMusic and<br>command-line test all work fine. What is the problem?<br><br><<a href="http://www.mythtv.org/wiki/index.php/Configuring_Digital_Sound#I_get_no_sound_from_MythTV_when_watching_TV_but_MythMusic_and_command">

<br><br>So far, I haven't been able to get the sound to work with watching TV,<br>DVD or listening to music in MythTV. I tried getting a help from a<br>friend who knows a lot more than me about Linux and MythTV (I am a
<br>newby), but he was not able to help me, either.<br><br>I am running MythTV ver. 0.2 on Suse 10. My sound card is: ALi M5455<br>with spdif-out (6ch).<br><br>I would really appreciate any help (hints, articles, ideas, etc.)
<br><br>Please, let me know if you need any more info about my system/configuration.<br><br>Thank you!<br><br>Ludmil<br><br><br><br>_______________________________________________<br>mythtv-users mailing list<br><a href="mailto:mythtv-users@mythtv.org">

What ended up working for me was, make sure ac3 and dts passthrough are both enabled. And then change both the audio and passthrough output devices to be ALSA:iec958. That's all I needed, hopefully it will work for you as well.
