Thom,

I'd be glad to contribute to LMCE. How do I properly get started? I don't want to cause any disruptions or grief for the real developers!

Thanks!

Thom, thank you again for pointing me in the right direction. This is now solved.

When I went through the A/V Wizard, I select SPDIF Coax and Y for both Dolby Digital and DTS. The fix was to then go into the admin site, change the sound card to "Audigy", Uncheck the "Use AC3/DTS pass-through" and reboot the media director. Everything sounds good now and since figuring out how to get scrolling to work with my Wiimote and sensor bar, I can retire my aging Xbox based Xbox Media Center! Thanks!

So I figured out how to get scrolling to work with the wiimote. I'm using a sensor bar with /etc/cwiid/wminput/ir_ptr. This includes the buttons config. When I'd try to scroll, the cursor would go to the bottom of the screen and nothing would happen. To get scrolling to work, you have to add in the acc_ptr config. I just added these lines from acc_ptr to the ir_ptr file:

Code:

Plugin.acc.X = REL_X
Plugin.acc.Y = REL_Y

Now I can scroll through my music/videos etc. I'll add this to the wiki.

You have a misunderstanding of the system.

We do not use xine-ui.

We use a player that takes DCE messages, based on libxine.

This player code is in src/Xine_Player in our SVN.

When Xine_Player starts, a configuration file is created for the libxine thread, based on configuration of your media director thread. Now, you can go to wizard > media director and change the sound card to "Manually Configured" ... at which point, you can manually modify /etc/pluto/xine.conf and change the sound settings there...

But this is a band-aid, and if you do that.. then.. okay.. we can't really help any further.

What NEEDS to happen, is you need to look at our asound.conf to see how things are configured, and look at what needs to happen to have our system output the correct sound configuration, either via a device template override, or through core code changes.

-Thom

Thank you Thom! As you've realized, I'm guessing my way through this as there haven't been many responses. I certainly want to stay along the recommended path for running LMCE, so I guess I'll be digging into asound.conf. The audio seems to be going out the right plug, but it's being decoded or something as my receiver displays "DEC ERR". Again, this is just when playing dvds through the orbiter. I'll dig around. Again, thank you very much for your help! I've been trying to get this running for a while now, and it seems that I'm close.

What command is issued to xine from the orbiter to play DVDs? Is there a option sent to change the output device that may be the problem here?

OK, here's what I've found so far:

By default, a netbooted Media Director 7.10, will play audio over Audigy SPDIF in the A/V Wizard, KDE Desktop, and Mplayer.

In the orbiter, there's no sound when playing a movie, but music is fine.

In KDE Desktop, I changed Myth Frontend audio device to ALSA:spdif from ALSA:default. Then I went into Kaffeine and change the audio driver from auto to alsa and the speaker layout to Pass Through. Playing a movie in Kaffeine on the desktop has audio. Upon returning to the orbiter, there's still no audio in movies.

How are movies played in the orbiter, that is different from Kaffeine on the desktop? They both use the Xine engine, from what I can tell. I'm going to set Myth frontend back to ALSA:default and try Kaffeine and then the orbiter again to see if Kaffeine still works. Thanks!

Thank you! From the lack of responses, it seems that I'm pioneering, so these are my notes as well as anyone else's. However, I'm concerned that I may have missed some details initially as I only recently started documented my steps. From reading through the ubuntu forums, and others, it seems that the audigy can be made to work with xine over spdif coax, so perhaps this is an issue with LMCE that just manifests itself this way. I've started over with a fresh MD build with Audigy 2. Onboard audio is disabled in the bios. The A/V Wizard and Setup Wizard Video both had sound. Mplayer has sound. As before, only Xine produces no sound. This makes me doubt that anything I've tried had any effect. Does anyone have a recommended order for testing?

In alsamixer, both IEC958 Raw and Analog/Digital Out are unmuted. It seems that generally, IEC958 should be muted, but I'm not making any changes anywhere yet.

In .xine/config, audio.output.speaker_arrangement is commented out (default). It's been recommended to set this to "Pass Through".

This is the asound.conf:

Code:

pcm_slave.convert48k {
pcm "spdif"
rate 48000
}

pcm.spdif_playback {
type plug
slave convert48k
}

pcm.asym_spdif {
type asym
playback.pcm "spdif_playback"
capture.pcm "plughw:0"
}

pcm.asym_analog {
type asym
playback.pcm "plug:dmix"
capture.pcm "plughw:0"
}
pcm.!default asym_spdif

There are 2 ~/.asoundrc files recommended to use with alsa and audigy. I'll try both, though alsa says that .asoundrc is no longer required.

I haven't looked in MythTV Front end to see what the default settings are, but it's been recommended to use the device "ALSA:spdif" and the Passthrough "default".

I've switched to an audigy 2 card and still xine fails to produce sound. I started out with a clean netboot md, as instructed, and got sound in the a/v wizard. I've implemented the .asoundrc file found on a ubuntu forum post for using audigy 2 over digital coax. I've made the mythtv front end changes, device ALSA:spdif, and passthrough default described in using an audigy card with xine in a google book. Still no sound. I've tried optical raw muted and umuted, though unmuted appears to be generally recommended. Could someone using an audigy card please post their audio setting in MythTV Front End, their ~/.xine/config and /etc/asound.conf files? Thank you!

What settings should I have in MythTV Frontend setup? I've read that I should have the device set to ALSA:spdif, Pass Through set to Default. I've tried that and also with the device set to ALSA:default. Thank you!

MPlayer and playing music work fine. Maybe it's helpful to post my /etc/asound.conf file. Does anyone see anything here that may be a clue. I've tried setting the passthrough device in ~/.xine/config to default, ALSA:default, ALSA:spdif, and ALSA:asym_spdif. It doesn't seem like changes to ~/.xine/config are having any effect. I even tried renaming to file and playing a dvd and the outcome is the same: video:good, audio:none.

Code:

pcm_slave.convert48k {
pcm "spdif"
rate 48000
}

pcm.spdif_playback {
type plug
slave convert48k
}

pcm.asym_spdif {
type asym
playback.pcm "spdif_playback"
capture.pcm "plughw:0"
}

pcm.asym_analog {
type asym
playback.pcm "plug:dmix"
capture.pcm "plughw:0"
}
pcm.!default asym_spdif

I'm working with .xine/config now, and still no sound:

tried:
audio.device.alsa_passthrough_device:default
audio.device.alsa_passthrough_device:hw:Audigy,0
audio.device.alsa_passthrough_device:hw:0,0
audio.device.alsa_passthrough_device:plughw:0,0

setting the audio driver to alsa or oss.

Do you have to start the MD each time you make a change. I had been for a while, but with these past attempts I've ssh'd in, made a change and tried playing a movie without restarting.

Could someone using an Audigy card and s/pdif please post their full config file?

My mornings now consist of eating breakfast over my keyboard while trying different config settings. It's been over a week and getting a little old. I'd love to start using LMCE. Again, mplayer plays fine, it's just xine that isn't producing sound. Thank you!

Mplayer plays dvd's fine through all speakers. My alsa settings are optical raw unmuted, analog/digital output unmuted. Xine is still not playing audio...

Glad to see it's working. I've not tried scrolling, but instead select the letters on the right to get to different movies. I'm still working out audio issues, so I've not really gotten to see how usable the wiimote is day to day yet.

OK, I set all levels umuted and full volume in alsamixer and still no audio playing DVDs. Any other thoughts? The wiki lists the audigy as full functioning, so I'm confident that this can work, but it's not easy to get there it seems. Thank you!

I did that immediately after posting here. I'm trying to make up for my whining about no audio! Thanks!
