BLSTR DAC with LineageOS

Argon ONE V3 RPi 5
1

Hello.
I am working on setting up my rPi5 with Argon One V3 case with the BLSTR DAC attachement on LineageageOS 20 (Android 13). I cannot seem to get the DAC to work. I cannot install the Argon One curl package since Android doesn’t have a terminal shell, therefore, I am trying to get it to work by modifying the config.txt file. I have uncommented dtoverlay=hifiberry-dacplus and tried dtoverlay=hifiberry-dacplus. It hasn’t fixed these issues.

Referring to this: https://www.hifiberry.com/docs/software/configuring-linux-3-18-x/
you can attempt to disable the PWM audio with that change:

dtoverlay=vc4-kms-v3d,noaudio

and additional move these 2 dtoverlay lines to the very beginning of the config.txt file.

dtoverlay=
dtoverlay=hifiberry-dacplus,slave

← This is the replacement in newer kernels for force_eeprom_read=0

Please check also the content of the referenced config_user.txt file !

Maybe this is not the answer you want to hear/read. In the past there have been some users on this forum with BLSTR DAC where the device was defective. To rule out if it is a hardware problem, please use a better supported operating system like PiOS first.

If you are referring to the argon module, on mine there are two lines for dtoverlay. The first is =hifiberry-dac and the second is =hifiberry-dacplus, slave (in the config.txt file). Try that?

Also, using PiOS, I had to do a right click on the speaker icon and select the correct output to make it all work…
