DAC+ / Raspbian / 3.18.3+

Hi Oliver,

the modules have changed again in 3.18.x. However that's not the problem here. Do I understand you correctly: with a fresh Raspbian it is working, but not after upgrading the kernel?

Can you please post the output of "lsmod". Most likely a module is not loaded because it is blacklisted.

Best regards
Daniel

Hi

Just to say I'm getting the same problem. I downloaded a fresh copy of raspbian, enabled wifi and then followed the instructions.

lsmod

modules look good so far. You're also using 3.18?
Please post the output of "dmesg".

Thanks so much for all your help so far. I don't know if this is completely correct but I was looking around the raspberry pi site and found this discussion

http://www.raspberrypi.org/forums/viewtopic.php?f=29&t=93015

If I follow the instructions i.e add a line to /boot/config.txt like this

tail /boot/config.txt
# no display
#config_hdmi_boost=4

# uncomment for composite PAL
#sdtv_mode=2

#uncomment to overclock the arm. 700 MHz is the default.
#arm_freq=800

device_tree_overlay=overlays/hifiberry-dacplus-overlay.dtb

then the green LED on the card comes on and aplay -l reports the correct card.

I'm assuming the new firmware has been recently released with the device tree in it? I haven't removed anything yet from /etc/modules and blacklist but I guess I could?

Thanks for your help
San

Hi,

it looks like the kernel team has decided to use this new code right now. Adding this device_tree_overlay seems to be the solution now. In the future we will provide an update script for our DAC+/Digi+ to allow automatic configuration.
However this will only with with DAC+/Digi+, not with the older DAC/Digi. I'm not sure if this really simplifies configuration for the users, but let's see.

Best regards
Daniel

Just for completeness - I commented out the lines in /etc/modules, rebooted and the card still worked.

Thanks again for your prompt assistance

Dear San,

we have tested this and it seems to work. Thank you for the link. The updated configuration guide is now online:

FYI the RPI Kernel team also published this http://www.raspberrypi.org/forums/viewtopic.php?uid=121689&f=29&t=97314 late this afternoon. It mentions another syntax. I had to get to use this to get LIRC to work.

Hi Daniel,

maybe you should add the alsa config in the new guide as it is still needed if you play direct via alsa.

And I observed that the new firmware is a bit different.
I was at 3.12 and configured pulseaudio so i can have two sound sources at the same time, this was working fine.
When two Songs where playing the CPU Load was at about 70%

Then i did rpi-update (to , reboot and:
First the sound is not as "loud" as before
And second the CPU Load while playing two songs decreased to 52-61%

The thing with the CPU is no Problem, but what is the reason why it is not as loud as before?

Best regards
Oliver

HiFiBerry team January 22, 2015 10:46

Pulseaudio is very special on the Raspberry Pi ;-) It seems to behave different on almost every Linux kernel version. I have really no idea, why the volume changed now. Are you sure, the mixer setting hasn't changed?

Best regards
Daniel

Oliver Winkler January 22, 2015 11:08

When you tell me which config files you want to see i can post them,
but i tried it two times, old kernel loud, new kernel silent

And yeah, pulseaudio makes me mad, at the moment im stuck at "[pulseaudio] module-udev-detect.c: Found 0 cards."...

But i tried it to with direct alsa, there is the same decrease of loudness. So it should be no problem of pulseaudio

Whats the output of "amixer"?

Oliver Winkler January 22, 2015 14:22

I could imagine that this 80% are the problem,

and another question:
Is it possible to use the DAC+ with two audio sources without pulseaudio?
Like the onboard Soundcard (Two times 'mplayer test.mp3')
Because with pulseaudio 5.0 I have about 50-70% CPU Load when playing two songs
And when doing this with alsa and the onboard soundchip 6% CPU Load

Yes, I guess, you should increase the volume there:
amixer sset PCM 95%

It is not possible to mix 2 streams with the HiFiBerry cards. The driver does not support this. The developer of the Raspberry Pi I2S sound system is not actively working on this at the moment, therefore I would not expect this to change soon.

Why do you need to have different applications using the sound card? Often there are solutions for a specific use case that work with a single application. Tell us more about your use case.

The Software which plays songs is written by us, and we use libvlc
When a Song ends it fades out, and before it is gone completely the next song fades in,
so that it is never silent.
And for that we have for a few seconds two "players" at the same time.

Best regards
Oliver

HiFiBerry team January 23, 2015 09:19

Another option for cross-fading is using mpd. I guess, I have a rough idea about your use case, we have other business customers doing similar things. There are complete solutions out there that might also fit your requirements. We would like to see, how we can help you here.

Oliver Winkler January 23, 2015 10:36

Hi Daniel,

i will take a look at mdp,
but next week im not in the office, so it might need some time ;)

To the concept:
RaspPi with AMP/DAC, micSD with all the music stored locally, fixed playlists, but it has to be possible to have two audio streams at the same time, e.g. for the fade out/fade in, announcements

At the moment is the only solution without a too high CPU load is to use the onboard soundchip, audio out through hdmi, and then extract the audio from hdmi

Best regards
Oliver

I have install newest version of Raspbian, run rpi-update etc. and do exactly as written in HiFiBerry instruction for 3.18.x And it seems to work (I do have sound via RCA plugs), but I have different informations than written in examples.

Hello,
I just ried to make all these things from above, but my new DAC+ is still not working.

With dtoverlay=hifiberry-dac it does not work, there is no signal output and i was expecting a LED on the DAC+ to light.

but it is visible with aplay -l

Karte 0: sndrpihifiberry [snd_rpi_hifiberry_dac], GerÃ¤t 0: HifiBerry DAC HiFi pcm5102a-hifi-0 []

Sub-GerÃ¤te: 1/1
` Sub-GerÃ¤t #0: subdevice #0

but amixer has still a problem: Unable to find simple control ...

with device_tree_overlay=overlays/hifiberry-dacplus-overlay.dtb there is no card detected.
root@hifi:~# aplay -l
aplay: device_list:252: keine Soundkarten gefunden ... (no soundcard found, michael)

It is definite a DAC+ working on a Pi Mod. B+, but it is only recognized as a simple DAC model without plus.
using 3.18.7+ with performed rpiupdate. Now i do not know if there might be a hw problem ...

kind regards
michael
