That would be awesome.  Then I could go into a room and do the "Computer lights on" or "Illuminate" from Demolition Man.

Well When it was starting up it was sending out the 02 6B 40 but I was getting back a '00 E0' Response.  Turns out my PLM needs the baud rate set at 19200.  Its working great now.  Discovered my lamplinc and is working perfectly so far.  I'll have to buy a few more fancy modules so I can play some more.

Interesting, I must have screwed something up because it had a bunch of extra commands in there.  I created a new group and it didn't have them in there.  Scanning right now.

Finally got around to doing some testing.  Right I have everything configured but I'm getting this error when i view the interfaces page:

COM Port on PC     Error: top parent device not found

Might want to throw something on the wiki to select a room and controller.

Also you have it checking the 'Implements DCE' checkbox and changing 'Comm Method' to  RS232 then edit Ruby.  After the ruby window closes you have them hit F5 to update the Device template window which resets those settings.

Right now this is what I'm getting in the log file..

Have you had any luck?  I've got my volume to work inside the UI but I cannot mute my card using either the UI or alsamixer itself. 

PLM and a lamplinc is on the way.  I think I got rid of my old x10 stuff because I can't find it anywhere.   

I'm interested in playing with the home automation section of LinuxMCE, I'll look ta picking up some hardware and give this a try sometime soon.  Used to have an old x10 system back in the day but got rid of it.  I'm interested in trying out Insteon.

Glad to hear its loading for you now.  Yea you'll have to do some tweaking to get the mixer to work properly.  I haven't played with the file yet I just copied what they had on the wiki. 

Doing some searching to see what other have done and this is what i've come up with for the audigy LS which I believe is very similar to the value.

Good luck,

[alsactl store]

It doesn't save the mixer on reboot, and you have to play a sound inorder to get it back in there so the App_Server fails on reboot.

I did find that you can issue the command alsactl store stores your current mixer settings and mine were restored on reboot, so everything is working now.

Let me know if this fixes your problem.

Update:  It loads but you can't control volume, so it will probably need some tweaking.

Well that seems to be the problem.

RichardP do you want to try the following and see if you can get it to load?

See if this command returns anything:

Code Select Expand

amixer controls | grep -i master

If not that is most likely your problem.  You have to create a new softvol control in ALSA.  Here is a reference link for more information:
http://alsa.opensrc.org/index.php/Softvol
http://alsa.opensrc.org/index.php/How_to_use_softvol_to_control_the_master_volume

Here is what I did to get it to work, as root I created the ~\.asoundrc file and it contained the following:

Code Select Expand

pcm.!default {
    type            plug
    slave.pcm       "softvol"   #make use of softvol
}

pcm.softvol {
    type            softvol
    slave {
        pcm         "dmix"      #redirect the output to dmix (instead of "hw:0,0")
    }
    control {
        name        "Master"       #Create the Master softvol volume control
        card        0
    }
}


Then throw out a speaker test so ALSA reads the .asoundrc file and create the softvol

Code Select Expand

speaker-test -twav -c2 -l1 
You should hear it go through a speaker test (the c option is the number of channels) Excute the same command as at the begining to verify you now have a master volume control

Code Select Expand

amixer controls | grep -i master should return something and you should be able to start App_Server. 

I haven't tested this with rebooting but I'm going to do that right now.

to quote my previous post: iirc the appserver segfaults when using amixer without a sound card. Do you have a sound card?
have been there...

Hari,  I have a sound card, and it works properly, there is audio and everything.
I believe the problem is that according to ALSA:

The Audigy LS does not have a master volume control. For analog output, use "Analog Front", "Analog Rear" and "Analog Center/LFE" for volume.

http://alsa.opensrc.org/index.php/Audigyls_playback

From what It looks like the App_Server is trying to access the the Master volume control.

Okay i threw the core file its dumping into gdb and this is what I found:

Core was generated by `./App_Server'.
Program terminated with signal 11, Segmentation fault.

Some random web browsing brought me to the ALSA wiki page for the driver i'm using. http://alsa.opensrc.org/index.php/Audigyls which states:

WARNING: The Audigy LS is a very basic sound card. It has no hardware mixer, no DSP, and no interpolators.

So right now I'm assuming that the reason it is segfaulting is because the card itself does not have a mixer on it and requires a software mixer inorder to work properly.  Can anyone verify this for me?  I'm going to swap my sound card with another as soon as I get some dinner.

RichardP

Looked at my hardware and it turns out i have a Creative Labs SB Audigy LS.  Also when I try playing a video in mplayer it says "Alsa-control unable to find simple control 'PCM',0.  I can get it to work by selecting the use a software mixer option but this might be causing some sort of an issue with my system.

Will investigate further, I can control the output using the alsamixer app.

There was one log file were I found it trying to start and it was throwing an error code of 139.

I'll have to look into the soundcard thing some more when I get home, maybe amixer is being weird.  Wish work didn't block ssh so I would have something fun to do all day.  I guess thats why its blocked.

Hello,

Have you found a solution to your problem?  I seem to be having the same issue as you.  I did notice in the LMCE launcher on the soundcard tab the driver box was blank, but the sound works..  Could this be the issue?  Still trying to find my way around on the system.

I've tried running the App_Server manually and I get a seg fault right away.

If anyone can help point me in the right direction it would be great.

Thanks,
Hodge
