Hi,

When I use the latest release of MoOde (6.71.), this release does not work with the Merus driver. Only after
sudo apt update
sudo apt full-upgrade

It work, but still with error. THis is worring me and why is the update needed.
See:

Olaf

Hi Olaf,

We have checked our driver and it is working fine in the last kernel update with Raspberry pi OS (currently 5.4.72). At some point when the kernel was update from 4.19 to 5.4 there was a bug that was already corrected. So I assume that is the problem.

Regarding the error: "snd-rpi-simple soc:sound: ASoC: failed to init link MerusAmp: -517" if you look at the bottom of the dmesg output if they driver was correctly probed you will see: "snd-rpi-simple soc:sound: ma120x0p-amp <-> 20203000.i2s mapping ok".

The reason you see a failed to init message is because it takes a few milli seconds for the i2c on board to start up, so it tries to probe the sound card driver until the i2c bus of the merus amp is available. But this is not an issue.

@moodeaudio we have seen that the merus-amp is working fine also with kernel 5.4.51 in Raspberry pi OS. I assume the solution will be anyway a kernel update.

Best regards,
Ariel
