Hi

I've tried the latest release on the Pi 2 and it doesn't boot.

Which release?
You have to use this image for your RP2.

It works now, and I am very impressed! The sound is just awesome, and the GUI is very usable as well. Why did it not work before? It was a combination of two problems:
  • There are multiple error messages during boot. I have listed them in an earlier post. However, it turns out that these messages do not harm the operation of the Hifiberry Amp+.
  • Both speakers were connected incorrectly. In both cases, one of the cables did not make contact. Because of the above error messages, I never suspected something as trivial to be the problem.

Anyway, it works now:
  • Raspberry Pi 2 Model B (obviously)
  • Hifiberry Amp+
  • Ethernet or WLAN, both work
  • Synology 5 bay NAS, shares via CIFS/SMB

The only thing I did on the command line was to edit /boot/config.txt and enable the hifiberry amp. All other settings (like adding the NAS, or setup of WLAN) have been done through the GUI.

My eventual target device is a Raspberry Pi Model A+, so I am looking forward to the official 0.4 beta release.

Edit: Hardware Volume Control does not work: I always get 100% volume out of the speakers, regardless of the volume setting. Software control works fine.

Thanks for that. I haven't seen this build mentioned anywhere though.

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-08 ... XD_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:
Code: Select all
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: )
Code: Select all
rm /etc/vconsole.conf
rm /etc/systemd/system/multi-user.target.wants/dhcpcd.service
reboot

When extracted I get a 0.fat file and a 1.img. The image doesn't work for me at all and just hangs without any obvious boot activity.

This problem was already discussed on the forum. Your unpacking program works wrongly, i used 7z and had the same problem with 2 files, renaming archive to .iso instead of extracting it worked in my case.

Hi falkin,

thank you for your report.

Static IP How To :mrgreen: :
set using UI - /etc/netctl/eth0 is generated OK.
then go to console and:

Code: Select all
netctl enable eth0
netctl restart eth0


now you have set static IP. This step is also reqired on the official 0.3 image.


This is strange, because it should work out of the box..
I'll check this soon.


Edit:
OK, found the reason causing this problem.
This image uses the latest netctl version (1.10).
As there is no way to check a statically configured IP address for correctness, they are excluded from automatic profile selection by default starting netctl 1.10.


Code: Select all
'ExcludeAuto='::
Whether or not to exclude this profile from automatic profile
selection. Defaults to `++no++' for wireless and DHCP enabled
connections and to `++yes++' otherwise.


The problem can be solved by adding ExcludeAuto=no to your profile.
Code: Select all
Description='eth0 connection'
Interface=eth0
ForceConnect=yes
SkipNoCarrier=yes
Connection=ethernet
AutoWired=yes
ExcludeAuto=no
IP=static
Address=('192.168.0.185/24')
Gateway='192.168.0.1'
DNS=('192.168.0.1')

Thanks for the help. Now got it running and glad I did. So much better than the alternatives.

Hi Frank

OK, found the reason causing this problem.
This image uses the latest netctl version (1.10).

OK. There is not problem for me, but can be difficult for some users.
As I have seen there is a lot of users, who aer not very familiar with Linux.
I think there is required to do it correctly from UI.
Unfortunately I am not enough familiar with UI code to do it.

BTW
Do you have any idea what to check about KingRex ?
It's strange.
On Rasp B+ or my laptop (Kubuntu) there is not such effect.
Have anybody seen similar problem with any other DAC ?
(too fast voice, sounds like analog disc plays too fast)

I have fixed this already in the code (image update comes soon).

No, sorry.
