RE: Raspberry Pi 3 as USB audio streamer - some audiophile settings to try...

Posted by soundchekk on January 9, 2017 at 06:12:21:
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.
