Hifiberry

[thorald]

Hello!
Anyone with experience with hifiberry?

Im trying to get a dacplus card working, but cant get it recognized.

I have tried different combinations of suggested configurations that i read on other places, including config settings from the official site, but nothing seems to get it going.

Any ideas?

You need to install these extensions

alsa.tcz
alsa-utils.tcz

There will be other dependancies loaded, but these are the top level.

Then add the following line to /mnt/mmcblk0p1/config.txt

dtoverlay=hifiberry-dacplus

Reboot your system

[thorald]

Thanks for the suggestion, but unfortunately it does not work.

I have both alsa and alsa-utils installed

added dtoverlay=hifiberry-dacplus config.txt
removed dtparam=audio=on, to disable the onboard sound.

Played around with different settings for
dtparam=i2c=on,spi=on,i2s=on

And other settings i cant remember, but nothing I do is working.

I have tried to install the other alsa stuff to but that does nothing either..

What software are you trying to use.

what is the output of

aplay -L

Is there anything in dmesg that shows what the problem might be.

[thorald]

I am trying to use vlc. My compiled version works with the internal, so there is no issue there.

Output of aplay -l is:

Code: [Select]

aplay: device_list:268: no soundcards found...
Dmesg gave some strange results:

What version of piCore are you running?

also, can you add dtparam=audio=on back to your config.txt, so that we can be sure alsa is setup correctly.

[thorald]

I am running picore9.0

ok, dtparam=audio=on

aplay -l

There is a driver missing

Bela,

drivers/regulators/fixed.ko is required for i2s in 4.9.y kernels

[thorald]

Ah that explains a lot.
Thought i was going mad for a second haha.

Ok, can i load the driver myself, or is it better to go with an earlier version of picore?

[thorald]
