RPI4 & HiFiBerry Amp2 or DAC2 HD Not Working

[nerd]

@Rochambeaux

this is obviously a Volumio issue

@Rochambeaux

I did an extensive search of the previous topics. Did not see anything in the past 2 years that was relevant.

I can not agree to these statements I’m afraid. Let’s facts speak for themselves:

1. HifiBerry’s dtoverlays are not following kernel’s 6.1 release cycle.
2. Volumio devs issued test release 3.728 regressing kernel; addressing issue you have reported with other HifiBerry DACs already. Said regression is included in all updates after Volumio OS 3.703 release.
3. There are various threads showing the problem and discussing work around in details:

Audio playback is slow with hifiberry dac on Pi5

You may try fresh install, then OTA update, make sure you have sound output, then install peppyscreensaver. Or You can try older volumio image ( eg. 3.661 )

Volumio 3.703 + Pi 4 + HiFiBerry DAC2 HD

Not good news, but thanks for reporting it

Pi4 and HiFiBerry DAC2 Pro

You’re just too good to me. That works. I hadn’t realised the setting had changed to Mixer Type = none so changing that to software worked. Thanks again

As a summary, for all HifiBerry DACs:

Update your Volumio OS to release newer than 3.703 (with kernel 6.1.69); test version at the time of writing this reply.
Add to the /boot/userconfig.txt:

dtparam=i2c_arm_baudrate=1000000

Perhaps I will write a post in the help section later on.

Kind Regards,
