Here you go folks. Raspberry Pi 3 works great. Plus some configuration clock tweaks to try :-). |

Hi. Welcome to the PI club. Most recent PcP is 3.10! Not 3.02. Numerous audio related patches went into the optional audio kernel of 3.10. Most recent Moode also comes with that specific audio kernel (and also squeezelite beside MPD) Running a 44.1 flac at 2%CPU load doesn't reflect the most efficient setup. I have it down to 0.4-0.7% Another hint: Try a buffer setting of e.g. -b 20000:600000 That'll give you a 600MB playback buffer. There'll be no network streaming during playback. And PcP also offers to turn off HDMI. Do that. It'll save you even more power. Enjoy. ----------------------------------------------------------------- blog latest >> The Audio Streaming Series - tuning kit pCP |

Why? I still don't use USB DACs anymore. Most of the tweaks apply to both approaches though. ----------------------------------------------------------------- blog latest >> The Audio Streaming Series - tuning kit pCP |

It's available in the admin or beta mode under tweaks if I recall it correctly. I don't use PCP anymore. I can't be of much help here. There's also another way of accomplishing hdmi = off afaik. Add to /boot/config.txt "hdmi_blanking=2" Good luck. ----------------------------------------------------------------- blog latest >> The Audio Streaming Series - tuning kit pCP |

His DAC filters most of the stuff above the audio band. His ADC filters most of the stuff above the audio band. His conclusion only means, that no matter what source he's using his DAC/ADC combo measures the same way (on his questionable tools) in the audio band. This has nothing to do with the noise originated from different sources. Nor it can lead to any conclusions related to the source. His measurement methods are pretty much ridiculous. And he keeps spreading his crap (doing it for years). As a starter - I recommend to read this: http://nwavguy.blogspot.de/2011/02/rightmark-audio-analyzer-rmaa.html Enjoy. ----------------------------------------------------------------- blog latest >> The Audio Streaming Series - tuning kit pCP |

Look. Since years Archimago tries to explain "Computer Audio" with his way of measurements. He is pretty immune against any feedback/criticism. And he seriously believes that he can prove everything, where professionals with measurement equipment worth ten thousands of $ fail. His measurements are OK for basic checkups. And that's about it. ----------------------------------------------------------------- blog latest >> The Audio Streaming Series - tuning kit pCP |
