So I got my RPi 3B! Amazon same day $71 total for everything.  :thumb:

I downloaded Moode Audio zip file. Extracted the image file. Format overwrite the SD Card, then wrote the image to microSD using USBIT
http://www.alexpage.de/usb-image-tool/

I tried to use Rufus imager like Deepak recommended, but it couldn't see the SD card in device field.

After writing the image I glanced at the SD drive with windows explorer before ejecting the SD card, files were there.

Inserted SD into Pi, connect USB to Pi, power on DAC in USB mode, connect ethernet cable, link lights active. Power on Pi, browse  http://moode but I get nothing.

Check DHCP server for moode client, it is there. Try to nav to moode by IP address, no response. Not even with explicit port :80 suffix.

Not sure what to do now. How do I try again? Is it safe to just unplug the PS from the Pi without software shutdown command? Can't remember if I read that pulling the plug can damage it.

Moode setup instructions:
http://moodeaudio.org/docs/readme.txt
Pretty simple... hard to mess it up, unless you're me  :lol:
Thanks!

I was able to putty in and shutdown. I reinstalled the SD and unplugged the USB. Restarted and it worked. Plugged in USB and refreshed browser, all OK.

Thanks Deepak!  :)

Got it dialed in nicely. Resampling to 352k at 32 bits gives a nice sound. Now just listening and enjoying.

Good news, Rich.

You can see that 16/48 flac Czech station on the radio list - it's # 12 on my list so it should be close on your fresh install.

How are you getting your files to Moode? USB attached to Pi?  Over network?

And now that you've done Moode, you can load up Picoreplayer in a few minutes and try that too for kicks. Deeep set of filtering options.

It seems like you can now run LMS and Picoreplayer on the same Pi. Cool.

Gettin cheaper and better all the time.

Performance unimaginable for the price just couple of years months ago.

Tons of great radio stations, including Czech Classical flac. I've not listened to it yet.

Is it possible to add my own internet radio stations to the list?

My wife and daughter want it to play Spotify real bad. Is that possible? I guess I'd look for linux spotify app (my first instinct suggests it doesn't exist.)

As for filtering, etc. I've set Moode to "resample" from 44.1/16 to 352.8/32bit via "SoX: very high quality." That made a really nice improvement in tone and refinement compared to original redbook flac. More info:
https://sourceforge.net/p/soxr/code/ci/master/tree/README

Then I picked an output filter on my DAC that got rid of the hyper spacious hyper detail and made it like normal music listening without the mental fireworks that audiophiles love about the Vega DAC. The DAC is so revealing, it can be a bit rough on remastered CD recordings of 60s jazz, etc. I used Trane My Fav Things to pick which filter since the soprano is sensitive to those tone changes. That's all I've done so far, but after those two changes, I thought of you and said to myself, "all done at least until I hear from Mike... "

Moode has an optional Advanced Kernel that you can install which is somehow better than the standard core, but only runs on Pi2 or 3. So I turned that on also, but did so before I started listening, so I don't know if SQ changes. They say it does.

OK so when you run a squeezebox clone like PiCore, then you are also running the LMS on the Pi also. I was thinking you were still running server on separate box like the old days. Does LMS and PiCoreplayer install together as a package, or separate installs? I'll have to read about that. I think I still have an ooooold slimserver running on my NAS  :shock:

I am playing music now from flacs on my NAS via wired ethernet. I have WAVs on the nas too, and Moode can navigate the wav folders but no music files appear in the folders. So it seems to need a metafile header of some type to be able to display it. No problem, I've been meaning to rerip those to flac for a decade.

The Moode player was a bit flaky when I first started using it. I was worried that it was buggy and annoying. Pause button wouldn't work, inverting the song timer would restart the song, Clear and play would not clear, on and on. But that was because of all the config setting changes I was making without reboot. After a reboot it was bug free and rock solid all night. Boots in a few seconds.
I'll check out PiCoreplayer
Thanks

My wife and daughter cook together while listening to music, and their music is all on Spotify, so they wanted to play Spotify on the stereo.

Easy, just turn on airplay in Moode Audio configuration, set the airplay name and voila. Now they can play and control Spotify from their own (apple) phones. Even volume level can be controlled by airplay if you turn that feature on.

Is there an app to do "airplay" from Android?

Also, Spotify Connect will be integrated into next release of Moode.

Hey Rich,

Several Airplay Apps for Android listed here...

Would Twonky Beam work for you?

Thanks for the list Dave. I'll check it out.
Twonky link says "not available in your country yet," It's not in Google Play. No biggie, my Sonos works fine for streaming.

Airfoil will send from my laptop browser to RPi, but there's no Android version for sending, only for receiving.

I guess linux needs a way to run browser apps on RPi and send the audio out through the audio player, like WDM. Does that mke sense?

Moode didn't work out so well for me. Airplay worked once, then broke. Then I tried playing music from flash drive, it saw the tracks but couldn't play them. The interface was OK, I'll might it again sometime.

A friend suggested I try Volumio, it's supposed to be very easy. So I'm trying that out today. Moode didn't sound fantastic until I activated its 'SoX resampling' feature. I hope Volumio has as good sound quality or a similar interpolating resampling feature. If not I'll have to try to debug Moode to make airplay work so my girls can stream to it.

I learned how to use the windows command line program DISKPART to remove Moode's linux partition from my SD card. The SD only showed 60MB total capacity when I tried to format it for Volumio. Apparently this is normal behavior for Windows trying to format removable linux drives.
