HiFiBerry team You need to configure the drivers first. The easiest way is using the HiFiBerry Installer:
http://support.hifiberry.com/hc/en-us/articles/205389831-HiFiBerry-installer
If you want to configure it by yourself, you will find the documentation here:

pi-user Hi Daniel,
which distribution is in HiFiBerry Installer included? I have the RASPBIAN JESSIE LITE because it is very fast and small.
I have another question. Can I use the GPIO pins that sticking out from the Amp+ for other purposes?
Thank you very much. :)
-
HiFiBerry team Raspbian Lite is not included, only the full version.
For the GPIOs check out this documentation:

What should I do now to integrate my Amp+ right?
Thank you for your help. :)

pi-user If I type dmesg then I get the following:

HiFiBerry team The Amp+ is configured correctly. You see that it is listed as sound card:

pi-user Hi Daniel,
thank you, but what is this:
[ 4.542984] snd-hifiberry-amp sound: ASoC: CPU DAI (null) not registered
[ 4.543027] snd-hifiberry-amp sound: snd_soc_register_card() failed: -517

[ 4.554703] snd-hifiberry-amp sound: snd_soc_register_card() failed: -517Should I ignore it?
Thanks.
-
HiFiBerry team Yes, you can ignore this. These are temporary errors as there are dependencies that are loaded later.
Best regards
Daniel -
pi-user Super, Thank you. :)

SkylerAlbran Can you please share me the details of the setup you are using including the Raspberry Pi and the Amplifier?
Can you please share all of your hardware details and their specifications?
I am looking for a Raspberry Pi based amplification?

HiFiBerry team Hi Skyler,
you will find the details on the HiFiBerry Amp+ on the product page:

HiFiBerry team Hi,
aplay is not a good tool for tests. Check out our article on test sounds:

Best regards
Daniel -
pi-user Thank you.
I'll test ist soon.
Can I ignore the error messages from mplayer?

HiFiBerry team Looks like a process is already running that uses the sound card:
"open '/dev/snd/pcmC0D0p' failed (-16): Device or resource busy"
You need to stop other applications that use the sound card.

pi-user I installed sox.
play -n synth sine 1000
play FAIL formats: can't open output file `default': snd_pcm_hw_params error: Invalid argument
What's wrong here?
Thank you.
-
pi-user play -n synth sine 1000 --> works if I activate the entry in file /boot/config.txt
# Enable audio (loads snd_bcm2835)
dtparam=audio=onWhat is this entry (dtparam=audio=on)?
I have this taken out because I thought that this entry for the onboard sound card is and I do not need this, because I use my own soundcard (Amp+). If this entry for the onboard sound card? Should I comment out this or should I just leave it like that?
-
HiFiBerry team The dtparam=audio=on is for the onboard sound. You should disable this.
You still get the error message because there is still a process using it. What distribution are you using? The easiest way to setup te system is our HiFiBerry installer:

Daniel -
pi-user I have the RASPBIAN JESSIE LITE because it is very fast and small. I need no xServer.
-
HiFiBerry team Most likely you have a process running that blocks the sound card. Also check /etc/asound.conf. It could also a permission problem. As we don't use Raspbian lite, it is hard to say what might be the issue here. You might need some low level permission debugging with strace.
Best regards
Daniel -
pi-user Can I remove the xServer (X-11) environment from raspbian, if I use HiFiBerry installer?
-
pi-user When do you want to install the RASPBIAN JESSIE LITE in HiFiBerry installer?
Many people will be happy about it. :)
-
HiFiBerry team We don't plan to support this as there are not many people using this. You can remove any package you like from the full Raspbian installation. But it is not even needed to remove it. Raspbian by default doesn't start the graphical environment but boots to command line.
Best regards
Daniel -
pi-user My project works with HiFiBerry installer. :)
How and where can I upload a picture of a project to your Homepage?
-
HiFiBerry team Hi,
just post the project including pictures under http://support.hifiberry.com/hc/en-us/community/topics/200398351-Your-HiFiBerry-installationFrom time to time we will publish projects we like under customer projects.
Best regards
