Problem configuring AMP+

Hi,
I'm trying to make the Amp+ working but I am getting an

root@MusicBox:~# aplay -l
aplay: device_list:252: no soundcards found...

Error after following the tutorial on the site, maybe someone can help me understanding what I am doing wrong?
I installed pi-musicbox starting from the disk image that they distribute on their site, the server is up, I can connect to the Raspberry and, before trying to configure Amp+, I was also able to play music.

Just to give you an overview of the system:

root@MusicBox:~# uname -r
3.18.3+

I followed the 3.13+ tutorial.

root@MusicBox:~# rpi-update
*** Raspberry Pi firmware updater by Hexxeh, enhanced by AndrewS and Dom
*** Performing self-update
% Total % Received % Xferd Average Speed Time Time Time Current
Dload Upload Total Spent Left Speed

*** Relaunching after update
*** Raspberry Pi firmware updater by Hexxeh, enhanced by AndrewS and Dom

Here is my blacklist file

root@MusicBox:~# cat /etc/modprobe.d/raspi-blacklist.conf
# blacklist spi and i2c by default (many users don't need them)

# blacklist spi-bcm2708
# blacklist i2c-bcm2708

And here is the /etc/modules file

root@MusicBox:~# cat /etc/modules
# /etc/modules: kernel modules to load at boot time.
#
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.
# Parameters can be specified after the module name.

# snd_bcm2835
snd_soc_bcm2708_i2s
bcm2708_dmaengine

ipv6
bcm2708_wdog

# 8188eu
# 8192cu

# HiFiBerry Amp+
# snd_soc_bcm2708
# bcm2708_dmaengine
snd_soc_hifiberry_amp

The snd_soc_bcm2708_i2s and bcm2708_dmaengine where already present when I first edited it, replacing snd_soc_bcm2708_i2s with snd_soc_bcm2708 returns an error on boot, so I just added the last line.

Also, /etc/asound.conf was already present, it looks like it is re-created every time I reboot

root@MusicBox:~# cat /etc/asound.conf
pcm.!default {
type hw
card
}
ctl.!default {
type hw
card
}

It is slightly different from the one in the tutorial, but anytime I edit it, it goes back to this content.

And this is the result

root@MusicBox:~# aplay -l
aplay: device_list:252: no soundcards found...

I suppose that there is something that I need to change in the config since I am not using a plain Raspbian installation, but unfortunately I don't know so much about Linux, and following step-by-step a tutorial is the best that I can do.
Maybe someone has some idea on how to make it work?

Also, here is the boot log, that shown that alsa cannot be started.

Hi Simone,

the problem with PiMusicBox is that it always overwrites /etc/modules and /etc/aplay.conf on reboot. I'm not sure if the new release has been tested with the Amp. I've sent a patch to the developers some weeks ago, but I'm not sure if this has been integrated now. Are there any comments from the developers about this?

Best regards
Daniel

Hi,
I found this article on MusicBox GIT, I post it here 'cause maybe it can be helpful to someone other.
Didn't try it yet, I'm going to do it now, I'll post the results.
Thank you Daniel for your reply!

Forgot the link: enabling the HifiBerry AMP on PiMusicbox #171

Anyway, no luck even with a new installation.
I read in your "supported distribution" page that it will be supported "soon". Does this depend on you or on MusicBox team? Do you have any estimates about the release date?

Thanks,
Simone

Hi,

in general it needs the correct driver and PiMusicBox must configure the system correctly. It seems that the 3.18 kernel has a problem with the Amp, we have to look into this. However, for everything in PiMusicBox, the developer of PiMusicBox is responsible. We can help, but we can't change things in PiMusicBox.

Best regards
Daniel

Hi,
I have the same Problem.
Musicbox seems not to Change the /etc/modules file, but the /etc/asound.conf file.
There is a hint in the GIT Musicbox #171 post at the end, applying this results in a correct /etc/asound.conf after rebooting.
But this also doesn't Change the Situation, aplay -l Shows no soundcards found.

There seems to be really a Problem with the kernel and the AMP+.

Best regards
Edwin

Yeah,
I also noticed that. I tried to edit their script and succeeded, but even with the /etc/asound.conf file configured correctly it still doesn't work.
I tried both with 3.12 kernel and with 3.18 by upgrading it with rpi-update but really can't make it work.
I opened a topic on their forum, hope to receive some help from there.
Ciao,
Simone

The "no card found" problem seems to be an issue of the 3.18 kernel. We will look into this.

Ok, the problem has been identified. As a fast fix, download the device-tree-file here: https://www.hifiberry.com/files/hifiberry-amp-overlay.dtb and copy it to /boot/overlays

Then configure the device tree overlay as:
device_tree_overlay=overlays/hifiberry-amp-overlay.dtb

I've updated the guide here:
https://www.hifiberry.com/guides/configuring-linux-3-18-x/

We will create a patch and send it to the kernel developers and hope it will be included in the official Raspberry Pi kernel soon.

Best regards
Daniel

Hi,

I have just run update, upgrade and rpi-update on my amp+ setup and am now getting the "no soundcards found" problem. Prior to this my amp+ was working great - why do I have to meddle?

Anyway, I have just applied the changes for the fast fix in Daniel's post above but it has not worked. aplay -l still reports no soundcards found.

Some quick searches turned up this page https://github.com/raspberrypi/documentation/blob/master/configuration/device-tree.md

It suggests that the changes to config.txt are more extensive - to quote...

The main impact of using Device Tree is to change from everything on, relying on module blacklisting to manage contention, to everything off unless requested by the DTB. In order to continue to use external interfaces and the peripherals that attach to them, you will need to add some new settings to your config.txt :

# Uncomment some or all of these to enable the optional hardware interfaces
#device_tree_param=i2c1=on
#device_tree_param=i2s=on
#device_tree_param=spi=on

# Uncomment one of these lines to enable an audio interface
#device_tree_overlay=hifiberry-dac
#device_tree_overlay=hifiberry-dacplus
#device_tree_overlay=hifiberry-digi
#device_tree_overlay=iqaudio-dac
#device_tree_overlay=iqaudio-dacplus

# Uncomment this to enable the lirc-rpi module
#device_tree_overlay=lirc-rpi

# Uncomment this to override the defaults for the lirc-rpi module
#device_tree_param=gpio_out_pin=16
#device_tree_param=gpio_in_pin=17
#device_tree_param=gpio_in_pull=down

Are there more changes needed to config.txt than mentioned in Daniels' fast fix post?

The line

device_tree_overlay=overlays/hifiberry-amp-overlay.dtb

should be enough, that's what I tested here.

Check the file name and make sure it is correct and located in /boot/overlays

BTW: The missing file will be integrated in the next Raspberry Pi kernel, the pull request will be merged soon:

Hi Daniel,

I checked and double-checked everything with no change. I still get "no soundcards found".

I have a spare unused sd card here so I have put a fresh install of Wheezy 2014-12-24 on it and configured it from scratch.

After sudo apt-get update - sudo apt-upgrade - sudo rpi-update, I followed the new software configuration step by step. After the last re-boot I log-in and type aplay -l and I get "aplay: device_list:252: no soundcards found...".

Something is wrong somewhere but I can't see where.

I hope you can help
Thanks

On a new Raspbian installation you still have to remove the drivers from the blacklist.

Please post the output of
ls -l /boot/overlays
cat /boot/config.txt

Thanks to everyone for your help!
I'll try the new solution this evening...
I only have 1 question, just to be sure:

when you say "remove the drivers from the blacklist" this means that I have to comment out that lines, right? Like

# blacklist i2c-bcm2708
# blacklist snd-soc-pcm512x
# blacklist snd-soc-wm8804

This should be enough, am I correct?

Yes, this should be enough.

I have successfully got around the problem by changing the line in /boot/config.txt to "device_tree=" which disables the new device tree features and goes back to the older methods of configuration.

Hi David,

you might need a newline character at the end of the device_tree_overlay line.

Ok, this is very strange. While the setup works on Raspbian, it doesn't on PiMusicBox - even with the same configuration. We have to look into this later. I'm not sure what could be the issue here.

You can use the workaround from David and add the line

device_tree=

in /boot/config.txt and configure the driver in /etc/modules:
```
bcm2708_dmaengine
snd_soc_tas5713
snd_soc_hifiberry_amp
```
This seems to work.

Best regards
Daniel

Yeah!
I can see the card now!

Thank you everyone for your support!

If I use this workaround my raspi don't start again after reboot...

Are you using PiMusicBox with kernel 3.18.3? In this case, I have no idea why your setup isn't booting, as it seem to work here and for other users.

No I'm using Raspbian Wheezy (Image 2014_12_24). I update the kernel how describe in the how-to. After the update the hifiberry-amp-overlay.dtb is already on Raspberry.

I'll try the musicbox today...

Hi Robert,

Raspbian seems to behave a bit different. The overlay file is now included, but driver loading seems still be buggy. On Raspbian, use the device tree overlay file, but additionally configure the module in /etc/modules.

Best regards

Is there a difference between the tree overlay file which I coudl download on your site and the file which is update by raspbian?
I did blacklisted the lines in raspi-blacklist.conf, edit the boot.txt and configured the modules.

Will try again later with musicplayer and raspbian... really strange.

This worked for me after trying other ways for hours!

I did the same but if use device_tree= the Pi doesn't boot. If I use device_tree_overlay= it doesn't work (aplay: device_list:252: no soundcards found…). I suppose my amp is broken, that's why the raspi can't start when he is loading the right drivers.

Hi Robert,

no, this is not a signal that the Amp is broken. The driven even load if you don't add the Amp to your Raspberry Pi. The whole device-tree-overlay is very new (a few days) and it seems that there are still a lot of things that can go wrong. We haven't figured out yet why some distributions behave different from others even with the same kernel.

What is your distribution, what kernel version are you using. How dows you blacklist look like, what is the content of /etc/modules?

Best regards
Daniel
