Are you SURE there is a carriage return at the very end of that last line?

100% sure!

More good news. I tried this line in my fstab file and it works:

//192.168.0.50/Media/Music /mnt/tunes cifs defaults 0 0

Thanks Tom!

I can now see my music under /mnt/tunes on the Alix.

So now I just edit mpd.conf and I'm done?

I'm confused. Did you do this and have success from a mount command on the command line or did you put it in fstab? If the latter the only way to get it to work is boot it or mount -a which reads the fstab file.

I add the line to the fstab file and save it. I go to Putty and issue the command "mount -a", I enter the password, and it works. Then I issue the command "remountro" and exit Putty. Then I reboot the Alix and it hangs.

I then have to use Ubuntu on my main PC to edit fstab by removing the line I added. Then the Alix boots and I can see it again.

I'm guessing it's hanging waiting for a password. You might research the mount command on how to pass the user/password to it, try it on command line first to see if it gets past the prompt.

That makes sense because I need to enter a password when using the mount -a command. I know what I'm going to try in the morning.

Ok, more baby steps...

I seem to have everything working. The Alix can now be rebooted and it sees my Windows share under /mnt/tunes.

So I edited my mpd.conf file to this:

music_directory "/mnt/tunes"
playlist_directory "/mnt/tunes/mpd/playlists"
db_file "/mnt/tunes/mpd/tag_cache"
log_file "/mnt/tunes/mpd/mpd.log"
pid_file "/mnt/tunes/mpd/pid"
state_file "/mnt/tunes/mpd/state"
user "mpduser"
bind_to_address "any"

When I try to connect to MPD using GMPC, I get "error code 13:problems connecting to "192.168.0.100" on port 6600"

Everything seems correct, so I don't understand what's wrong. Hopefully this is the last piece of the puzzle!

Terry,
I never edited any of the state/log/db/pid lines, FYI. And what does your audio section look like? Is your DAC defined in mpd.config (i.e hw 0,0, etc). What does "aplay -l" give you in putty (should show your audio devices)?

Should I have my DAC connected to the Alix for this?

Check the line with "bind_to_address". There may be one commented out - # starts the line if it is a comment

Should be this:

bind_to_address "any"

TJHUB · « **Reply #690 on:** 15 Jul 2011, 02:15 pm »

Here is what my audio section looks like:

audio_output {
   type      "alsa"
   name      "My ALSA Device"
   device      "hw:0,0"   # optional
   format      "44100:16:2"   # optional
   mixer_device   "default"   # optional
   mixer_control   "PCM"      # optional
   mixer_index   "0"      # optional

The command aplay -l give this:

"aplay: device_list:235: no soundcards found..."

Tom:

I read that the "bind_to_address" should be set to "any", is that not correct?

TomS · « **Reply #691 on:** 15 Jul 2011, 02:20 pm »

Yes, my bad. I corrected my post. I'm not at home today so don't have access to my setup.

You would need a usb device hooked up for aplay to see.

Is it possible that when I added the user "mpduser" to my Alix, I don't have the permissions right or something?

Is Alix on 192.168.0.100 or 50?

The Alix is: 192.168.0.100 My Windows server is: 192.168.0.50

Ok, 1 step closer.

I edited my mpd.conf file to have "root" as the user and it worked. So I must not have the right permissions on "mpduser". How do I fix that?

So GMPC is working, sort of. I won't get into some problem I see yet, but I have a track ready to go, and when I click play, I get this message briefly on GMPC: "MPD reported the following error: "problems opening audio device"

I do not know if my USB DAC is compatible or not. I found 1 post where a guy was using my DAC (Music Hall 25.2) with a Vortex Box.

TJHUB · « **Reply #695 on:** 15 Jul 2011, 02:45 pm »

Sorry guys, I forgot to plug the USB cable into the Alix. I have now so that should help, no?

So now I'm the newest Alix user!

Thank you guys so much for all of the help. In the end, this was so easy it makes me sad that it took days to do something I could now do in 5 minutes!

So my only remaining problem is the "mpduser" on the Alix must not have the right permissions. I don't understand this stuff at all, so what do I do to fix that?

As root, you need to add mpduser to the audio group: adduser mpduser audio

Thanks Jim. It feels great that I got through this and it works!

I added mpduser to the audio group and that part worked, but GMPC still doesn't work unless I use "root".

From which machine are your trying to launch GMPC?
