For Mac users I'd recommend using XLD:
http://tmkk.pv.land.to/xld/index_e.html

I like XLD better than EAC as it handles metadata better in general, and if you have non-ascii/unicode metadata XLD does a better job with it than dBpoweramp, but it doesn't support automatically creating folder.jpg which is something you really want your ripper to do (for MPoD and other mpd clients). XLD is also not terribly intuitive to use, but it's ok once you figure it out.

Overall I'd still give the nod to dBpoweramp unless you're either trying to save money or insistent on sticking with open source software.

Hello Idolse and thanks very much.
Music on my external hard drive using ntfs is up and working so can confirm the settings you sent work ready for the next version .

I made a WiFi connection using a fixed IP at mpd to Gnome running on a second laptop, the connection times out intermittently, however it auto reconnects, and cannot damp my current enthusiasm, best look at my network later.

The sound quality (the number 1 priority) on initial listening is better than my previous supposedly bit perfect windows player, unless my judgment is colored by the success of getting it going ? I need plenty more listening time.

Very Happy - Thanks again for your great project and assistance.

Great! Glad to hear it's working for you - keep me posted on your sound quality impressions once you've got some more listening time in.

By Gnome I assume you mean GMPC, a bit odd that it's disconnecting - I'm actually going to include GMPC in the next release, and it's been running fine. That said in my case it's on the same machine, so it's possible that there is some network issue on your side as you suspect.

PostPosted: Thu 07 Jun 2012, 23:40    Post subject: sound muted after first install  

I just installed on an Alix for the first time. I know system works as I have been using VoyageMPD. Uses Alix/WDlivebook/WaveIO USB.

Install of MPDPUP was perfect.

the sample sound during install was good. Found the NAS, and updated the DB.

GMPC client connects/sees db and plays WAV files. No problem.

But no sound. I know alsa comes up muted on most systems. This is what it feels like. How do I unmute? Alsamixer not found.

All suggestions welcome. I did change decoder { plugin "sndfile" enabled "no" in mpd.conf as I believe this is required for WaveIO.

thanks all,
Walter

Strange, especially since Pet-240/Drew had no issues with the WaveIO.

Disabling sndfile is only required of older MPD releases - this was due to a bug that was resolved last august/september.

The waveIO showed up as a sound device when the setup wizard ran, correct? When the wizard asked you to play a test file did it make any noise?

It's also strange that you're saying alsamixer wasn't found - it's most definitely installed as I use it relatively frequently. Can you post exactly what the error message is when you type the command? It shouldn't be coming up muted - I have noticed with some sound devices it won't always reboot at 100% volume when the hardware volume control is enabled, but in general it makes noise.

Edit: I see you say the sample sound was good - that would indicate the WaveIO was working during the initial boot, almost wondering if it had some issue on the reboot.

edit2: Which volume control option did you select with the setup wizard? Disabling the volume would be a way to bypass alsamixer altogether.

Things to help me debug would be to paste the output of:
alsamixer
aplay -l
ps -e
ls /mnt/music

Thanks.

Just been having an argument with MPod, I found that the iOmega drive Im using on my "network", its standalone.... needs to have booted before the Alix gets started, in a normal situation this would not be an issue as the NAS or whatever would be on all the time.
Still sorting the coverart thing with MPod, in regards to the webserver you build into this, how do I get Mpod to see the local folder for coverart? Do I need to turn on the webserver through Putty? What would its address be?
I have bodgied up an indicator cable for the wave, I get indication of 44.1 output and a streaming output, now to bodgy a spdif cable......

Can you advise re the webserver please Idolse?

Thanks,

Drew.

I'm guessing you figured I didnt make music either...

However, I am assuming that Yamaha called their SPDIF inputs coaxial and put them under the Toslink ports........

So if you dont find something it may not be mpdpup, though Im curious why alsamixer isn't found, I did select bit perfect, no volume control in the wizard....

Thanks Idolse!

That error isn't that you don't have alsamixer, it's just returning 'can't open mixer', which means it's not finding a top level/default mixer. That error I've actually seen before - my Audiophilleo does the exact same thing, but all the other sound cards I've tested with have been fine, the Wave is the first that's done the same thing as Audiophilleo.

Type the following to get to your mixer:
Code:
alsamixer -c 1


Then use the up arrow to bring the volume to 100%, and escape to exit.

If you disabled the volume in the initial setup wizard I believe this shouldn't matter, but if you did enable the volume I think it makes a difference, I don't quite remember all the variations I played with before. (edit - I see you set it to be disabled, so really not sure exactly what's going on - hopefully getting into the mixer as described above will resolve it)

Note if you did select the hardware volume control odds are that it's broken - that was the case with the Audiophilleo - I'll be reworking how the hardware volume is configured by the wizards. Basically you need the following lines in mpd.conf to get the mpd volume control working correctly (in the alsa sound device config section at the bottom):
Code:
        mixer_device        "hw:1"
        mixer_type        "hardware"


Regarding folder.jpg, go into MPoD's settings, click 'MPD Server', then drill down into the server configuration you made. Scroll to the bottom, and where it says 'local cover art' add this url
Code:
http://<your Alix IP address>/
You could also give tunes.local instead of the IP a shot if that worked for you before.

In the box below that use the cover art filename convention you're using inside each album folder, e.g. folder.jpg.

After looking at my MPoD config it looks like I was also having problems with it discovering tunes.local, I have it configured to use the IP. On my iPad with MPaD it has no problems discovering tunes.local automatically, so I think something might be broken in MPoD, need to ping the developer on that.

One other thing to debug for me - do this before you mess with alsamixer if you can, I want to see how it was set up by default.

Type this at the CLI and paste the output:
Code:
amixer -c 1


I suspect that it may be booting up muted, though that means I need to figure out why the sound test was working. Anyway the theory is from this Arch wiki article:
https://wiki.archlinux.org/index.php/Alsa

If my theory is right I'll use the setup scripts to have amixer unmute the card.

PostPosted: Fri 08 Jun 2012, 21:11    Post subject: Mute on Alix -SOLVED!
Subject description: Thanks
 

Turns out is was the alsamixer mute. I had the same on VoyageMPD, but here could not launch alsamixer. Your command "amixer -c 1" showed the gui. While volume was at max, each channel is muted. To unmute, you have to go to each channel and toggle mute with the 'M' key. Voila! Sound. First impression is sound is very good. It is different from VoyageMPD on same hdw. Not a lot, but slight different presentation. Both are great. At first impression, I think mpdpup might be a little more laid back and flowing. Will do some critical listening to really get to know it, and then pop the VoyageMPD CF back in and see if there really is a difference or just my imagination. mpdpup is an absolute winner in ease of use. I suspect it will have the edge on SQ due to its smaller footprint.

Thanks for the help and for the wonderful mpdpup!!

Here is the output requested from Alix for completeness. I have to go back thru it and make sure I get everything back to original config to really hear it.

Subject description: Tuning for SQ on Alix
 

OK, this is great and all is working perfectly.

PET-240,
Once you get mpdpup making beautiful sound, may I tempt you with some SQ tweaks. I don't pretend to suggest this is perfect, its a work in progress.
My WaveIO has a very good power supply which already gives it a pretty good sound stage. mpdpup as configured by default makes great sound on the WaveIO/Alix combo. In my room its 10 feet behind the speakers and very nice. It is very analogous to CICS/CPLAY on an optimized WinXP.

To my ear on my system (YMMV) there are a couple of things that open up the sound and produce an expansive 3D stage.
buffer_before_play "100%"
opens up the sound

The following explodes the sound stage. Brings it out in front of the speakers and makes it wider than the speakers. Still stays deep, but very 3D. Some may like it more or less. Seems like there is some room to experiment here.

audio_output {
type "alsa"
name "WaveIO"
period_time "21333"
fragment_size "4096"
device "hw:1,0"
buffer_time "250000"
mixer_type "none"
mixer_device "disabled"
auto_resample "no"
auto_format "no"
}

Enjoy, and lets compare notes. Enjoy the WaveIO. Awesome with mpdpup! Cool

Excellent, very happy to hear we've gotten to the bottom of this. Appreciate the comparison to Voyage, I think the two of you are the first to try it out on the Alix 2D - my embedded system testing was on another board.

I still have a lot to learn about ALSA though - of all the cards people have tried with mpdPup the Wave is the first one that exhibited this behavior. I've personally used lots of different USB DACs/Converters for testing and never run into this. So does something in the hardware actually tell ALSA how to configure the driver?

The fact that amixer -c 1 launched the GUI means I still have a problem to solve in terms of the setup scripts as well - ideally I need a way to unmute from a BASH script without popping up a GUI.

Also keep me posted as to whether the unmute survives reboots.

Drew, I saw your question about the volume control on MPoD on their blog comments - this is indeed because you disabled the mixer - if you want the volume control enabled then you can replace the mixer_device "disabled" line from wlowes config with the two lines I mentioned a few posts back. 100% volume should be bit perfect (though the WaveIO guys would need to confirm), below 100% behavior won't be bit perfect, but quality is dependent on how the WaveIO guys present their capabilities to ALSA, so you would need to check with them - some of the Converters/DACs do have very high quality dithered volume controls.

@wlowes, PET-240, I think I've got an idea on how to unmute all the channels in future releases - If either of you would be willing to help beta test the next release let me know. I'm pretty confident what I want to do will work in general, but not sure if it will persist across reboots.
