Will it run out-of-the-box on a RPI B+?

Pi MusicBox
1

I am considering getting a brand new RPI B+ with the HifiBerry add-on board.
Will Pi Musicbox run without any re-configurations on a RPI B+ with the HifiBerry add-on?
Or should I better get an older RPI B ?

Thanks for any suggestions!

MusicBox 0.5.1 RC1 almost ran out of the box on my Pi model B+ with the Wifiberry DAC+.

The only thing I had to do after putting the image on my SDcard was updating the firmware to support the new Hifiberry using rpi-update (which had to be installed as well).

MusicBox 0.5.1 RC1 ran out of the box on my PI B+ with a HifiBerry. I didn’t do any updates.

However I do have some issues with RC1 (I don’t think hardware related). See my other posts.

Well I got a RPI B+ together with a hifiBerry DAC+. Unfortunately I’ve had no luck in getting it to work yet. When I set the output to analog Musicbox plays fine.
When I set the output to i2s there is no sound at all.

I tried the test tone image from higiBerry (http://www.hifiberry.com/guides/sd-card-images/) and the test tone plays fine.

Any suggestions where to look, what logfiles to check?

Are you setting output = i2s or output = hifiberry_dacplus ? You must set it to output = hifiberry_dacplus as per the comments in settings.ini. If you are setting it correctly then please try the very latest version (http://www.woutervanwijk.nl/pimusicbox/musicbox0.5.1rc2.zip) and provide the output of

  • lsmod
  • cat /sys/class/sound/card*/device/modalias
  • aplay -l
  • cat /etc/asound.conf
  • cat /etc/modules
  • cat /etc/modprobe.d/blacklist.conf

Thanks Nick. I was running MusicBox 0.5. Didn’t have the hifiberry_dacplus setting in settings.ini.
I will try with 0.5.1rc2.

Okay, I am now running Musicbox 0.5.1rc2 and have set output to hifiberry_dacplus.
I do have sound now! But when playing from Spotify the sound is very very stuttering.

Here are my settings as you asked:

Edit: I managed to fix the sound. In Settings.ini I set the output to:

output = alsasink buffer-time=300000 latency-time=20000

Spotify is now playing fine!

I did not release that version yet :slight_smile: Wanted to make sure if everything worked well, but it’s out now… lol

Hehe sorry!
