You don't need to do anything in ALSA generally.  All the settings are in the mpd.conf file.

you need to figure out the address of your sound card's coax out is.  From the CLI:
aplay -l

will list out the sound outputs available on your M-Audio.  You need to figure out from that what the address is.  It's probably 0,1 or something like that.

Then you specify your sound settings in mpd.conf.  If you want bit perfect use hw: or plughw:.  Disable the mixer, etc.  There are lots of posts on the forum about the ins and outs of defining your sound settings in mpd.conf.  The mpd.conf file is already written with everything you need, just uncomment the appropriate section for ALSA and change the sound card output address.

The mixer stuff only needs to be uncommented if you want volume control and cross-fade on mpd. If you want bit perfect leave it alone.

Code:

#audio_output {
# type "alsa"
# name "My ALSA Device"
## device "hw:0,0" # Uncomment this to get bit perfect switching between 44 & 96 khz, but you need to set the right device address
## format "44100:16:2" # optional - don't uncomment for 96Khz support
## mixer_device "default" # optional
## mixer_control "PCM" # optional
## mixer_index "0" # optional

So I installed and setup MusicIP's MusicMagicServer, http://www.amplifindmusicservices.com/what/downloads.php and analyzed all my music.

I've been googling at length looking for anyone who has managed to integrate the two.

The two ways I see it working:

1. The hard way:
-- allow me to choose a song to play in mpd, then have musicip know that I have chosen that song, and then queue up a bunch more songs in mpd based on that choice

2. The easier? way:
-- identify some other tool that has the ability to create an m3u that I can use the MPD MusicMagicMixer Hack http://mpd.wikia.com/wiki/Hack:MusicMagicMixer -- this hack talks of a player "MusicMagic" that I've been unable to find (The download only seems to have the Server in it for linux) which is unfortunate because it sounds ideal!

So has anyone managed to use the two together?

G 

Nobody does this? Has this been answered before and I'm not searching for the right keywords? Or maybe this is not even an MPD issue, it's with ALSA?

looks like its working now

thanks

installed mpd-git 0.16~alpha2 via AUR in arch

worked awesome!

sidenote:I will say its ALWAYS an adventure for me to get MPD configs and permissions correct on new installs, but alas its done and working (/me bangs head on keyboard).


thanks again for a handy script and your help.

Thank you so much for your time GadgetDave, both with the origional script and the recent diagnosis. My wife (the primary enduser) is very greatful as well

I shall look into updating MPD this evening

Again, thank you for all your efforts

OK, so I have duplicated the problem.

mpd 0.15.11 and mpd 0.15.12 do not play nice with the mms streams used by xmradio.   This is fixed in mpd 0.16~alpha2 (did not test alpha1), and works fine with mpd 0.15.0 through 0.15.10.
I recommend updating (via source) to 0.16~alpha2 if you are willing, otherwise move back to 0.15.10.

If I get a chance,  I may dig further, but since there is an easy solution (upgrade mpd to latest source), you should be able to fix yourself quickly.

Good Luck.

i have this working, i believe it was due to permissions and possibly pulseaudio.  i'm still having an odd problem with the on board hda intel audio device...  sometimes when i reboot there is an error loading the driver, other times there isn't.  doesn't make a lot of sense...

I will have a look.  The most likely cause is XMRadio online web changed something again that requires a small change to the script.

I'll let you know when I have a chance to diagnose.
