HiFi Berry DAC2 HD Support + Moode 8

[dmueller]

Hi All,

Attempting to understand either an issue or what I'm doing wrong.  

RPI 4 2gb
HiFi Berry DAC2 HD
Moode 8.0

Not able to get the DAC2 HD to function w/o error.  I have applied the DT overly as suggested.  Open to suggestions please.

Receiving this error:

Failed to open "ALSA Default" (alsa); Failed to open ALSA device "_audioout": No such file or directory

In Audio Config try reseting Named I2S device to None then reboot then set to your actual I2S device then reboot again.

I2S device changes always require a reboot because they use Linux kernel drivers which don't support hot plugging like USB audio devices.

Hi Tim --- Thank you for the quick response.  I set everything to "none". Rebooted (twice because why not).  Set the DT Overlay to the DACPLUSHD, rebooted.  Getting the same error.

Let me know how I can help trouble shoot or if I'm still doing something incorrectly.

Thank you btw!

There seems to be a fix in the kernel 5.15.25

Looks like I'm waiting for a moode update to use this board. (:

We will try to get an update out this weekend that includes a kernel bump and bug fixes.
