Volume control not working on HIFIBERRY DAC2 PRO

[lomdar67]

Probably not a issue just me being stupid:

NO VOLUME * Please check your volume setting on your device and use your device to increase the volume. If setup/dac is recognized it you will see volume changes also updating in the HifiBerry Audio Controls.

If I understand it correctly volume control with e.g. the iOS or Android Tidal app should be working, right?

I have a HIFIBERRY DAC2 PRO with a Raspberry 3B+ running HifiBerryOS (latest version). I've installed the latest version of the docker image (yesterday). So far Tidal Connect is working very well, but I can't control volume. Is there anything I can try or do?

Best regards,
Michael

Same configuration. Same problem

Sad to see the volume control is still not working on the HIFIBERRY DAC2 PRO. yes, volume control should be working via the mobile IOS/Android device.

Can you please help me debug this issue as i dont own a HIFIBERRY DAC2 PRO

1. Please pull/download the latest version
2. Install using the installation script. During installation it will ask for a playback device (typically your DAC is the first choice '0')
3. Open the speaker-controller application using the script: ./show-speaker-controller
4. Try and play a song from Tidal using your mobile device
5. In the UI terminal check if the speaker_controller app does anything for you e.g. 'P' for play/pause -/+ for Volume controls
6. If the above works: try with your mobile IOS/Android device to change the volume
7. IMPORTANT: Exit the Application using tmux key-combination: ctrl+b, d (detach)

Repeat steps 2-7 with a different audio device (maybe audio mixer or sysdefault works, i am curious to know).

Hope this helps you both.

Thanks,
Tony

Sure, Tony. And let me say I am a pig in the mud with the work you have done as is it now.... Thank you very much.
The UI shows complete control. Says the artist, the state... everything. If I touch the volume control, the bars with ### become narrower or wider, so the commands are catched by the speaker controller app... The only issue is that those controls have no effect

Hello Tony,

I did pull the latest Git updates around 19:00 CET.

These are the devices that show up:

0=snd_rpi_hifiberry_dacplus: HiFiBerry DAC+ Pro HiFi pcm512x-hifi-0 (hw:0,0)
1=sysdefault
2=default
3=dmix

I did a install with all 4 devices.

For device 0:

P,L,K do work
When I press + or - I see, that the volume in the Tidal iPhone app and speaker_controller changes, but the volume I hear doesn't change at all.

For device 1:
same as device 0

For device 2:
same as device 0

When I select device 3 I see Tidal Connect in the app and I can connect, but I can't play anything.

Hope that helps.

Best reagards,
Michael

It seems that speaker_application works as expected (and controls are captured correctly), but the commands are now trickled down to the DAC volume / DAC device for some odd reason. I will need to research the drivers on this device, but will be tricky as i have no way of testing the HIFIBERRY DAC2 PRO.

Question.
What is your dtoverlay for your DAC in /boot/config.txt ?

this is mine (and hifiberry-dac is the one to use even that i have a DAC+DSP)

dtoverlay=vc4-fkms-v3d,audio=off
dtoverlay=hifiberry-dac

Would you be able to change the dtoverlay and try if those settings work?

[jrotaetxe]

Will check with yours...
mmmm. Config txt is R/O. Have to extract the memory card to edit from outside. Will try tomorrow

This is strange. I didn't have a overlay for the DAC:

# Please note that this is only a sample, we recommend you to change it
to fit # your needs.
# You should override this file using a post-build script.
# See http://buildroot.org/manual.html#rootfs-custom
# and http://elinux.org/RPiconfig for a description of config.txt syntax

# We always use the same names, the real used variant is selected by
# BR2_PACKAGE_RPI_FIRMWARE_{DEFAULT,X,CD} choice

# Enable I2C and SPI
dtparam=i2c=on
dtparam=spi=on
dtoverlay=i2c-gpio,i2c_gpio_sda=0,i2c_gpio_scl=1
dtoverlay=vc4-fkms-v3d,audio=off

I added you overlay and did a reboot

dtoverlay=hifiberry-dac

But after the reboot the line was changed to

dtoverlay=hifiberry-blocked

[lomdar67]

Will check with yours... mmmm. Config txt is R/O. Have to extract the memory card to edit from outside. Will try tomorrow

Just remount the partition as read/write:

mount -o remount,rw /dev/mmcblk0p1 /boot

[TonyTromp]

I use mount -o remount,rw /boot which works similarly as described above.

Also i find a setting that could be related to our issue, as i read about HIFIBERRY DAC2 having a Hardware Volume option.

Can you execute the following command:

/opt/hifiberry/bin/alsa-mode

This returns SOFTVOL for me and i am curious if its different on your device.

[TonyTromp]

btw very strange that you dont have a overlay for your DAC at all (and the soundcard works)?
For me the settings were added automatically (since latest release) and now works out of the box.
In previous versions i needed to set it manually to dac+dsp overlay else it would play any audio.

Did you have a look at: https://www.hifiberry.com/docs/software/configuring-linux-3-18-x/ ?

My guess is you need the same dtoverlay as jrotaetxe :

dtoverlay=hifiberry-dacplus

After that and a reboot i am curious about the

/opt/hifiberry/bin/alsa-mode

output.

Also i found the following binairy. which doesnt do anything on my DAC, but maybe does something on yours.

/opt/hifiberry/bin/fix-dacadcpro-mixer

This is my output for the amixer command. Please let me know if you have differences

amixer

Simple mixer control 'DSPVolume',0

From documentation:
https://www.hifiberry.com/docs/data-sheets/datasheet-dac-adc/

"Hardware volume control for DAC. You can control the output volume using “alsamixer” or any application that supports ALSA mixer controls." - I am not sure if this explicitt means that volume can ONLY be set through alsamixer.

Some of me search lead to this thread on Volumio: https://community.volumio.org/t/solved-rasp-b-hifiberry-dac-nohardware-volume-control/2467/3 and indeed suggests the volume control is done in hw. Not sure how i can make the tidal_application to use the right control.

So my guess is that we need a working dtoverlay and then set

select-playback-device

to use dmixer (digital mixer)

[lomdar67]

I use mount -o remount,rw /boot which works similarly as described above.

It also returns SOFTVOL:

# /opt/hifiberry/bin/alsa-mode
SOFTVOL
#

[lomdar67]

/opt/hifiberry/bin/fix-dacadcpro-mixer

Yes, the DAC was working without the overlay. It is a fresh HiFiBerry OS install with the latest version.

I added dtoverlay=hifiberry-dacplus and this gets not changed after reboot.

alsa-mode is still SOFTVOL after reboot, no output from fix-dacadcpro-mixer and here is amixer:

# /opt/hifiberry/bin/alsa-mode
SOFTVOL
