Hi
My config:
- Rasp Pi 2 B with 2 A power supply (Raspberry)
- iFi nano HD USB DAC 32bit/384 kHz
or
KingRex UD384/32bit
both are battery powered
- Pioneer A-777 or A-5 Amp
- Infinity Kappa 8.2i
Volume control disabled
static IP
source: local sd card
Rasp Pi B+ is a little to slow for high quality audio.
On 192 k/24 bit or faster you can hear some digital noise and crackles like old analog disk.
On Rasp 2 B there is not such problem.
I tried some 24/383 .dff and something like this:
http://www.lindberg.no/hires/test/2L-087_stereo-DXD_06.flac - 24/352 DXD - over 10 Mbps
quality is perfect. (ifi has native DXD and DSD)
load is up to 20% on the one core.
KingRex problem:
With Rasp Pi B+ works OK, except craclkes
With Rasp 2 B any .vw, flac, DXD or 24 bit .wav sounds like analog longplay 33 rpm played on 45 rpm,
but some .wav 16 bit/ 44 kHz sounds OK.
When ifi and KingRex are active, KingRex plays with breaks (because voice speed on it is double)
ifi plays OK.
Static IP How To :mrgreen: :
set using UI - /etc/netctl/eth0 is generated OK.
then go to console and:
netctl enable eth0
netctl restart eth0
now you have set static IP. This step is also reqired on the official 0.3 image.
on Rasp Pi 2 B now you have two addresses:
- one static
- one reached by DHCP
so you have to do the following:
(first step you can skip, but is recomended if you don't use de keyboard :mrgreen: )
rm /etc/vconsole.conf
rm /etc/systemd/system/multi-user.target.wants/dhcpcd.service
reboot
