Rasberry pi 3 con hifiberry amp2 el sonido se entrecorta

Hi @JordiEst,
Can you clarify whether the device is connected to a WiFi network or not and whether WiFi credentials were provided during its provisioning?
If the method suggested in our previous response didn’t work for you or if you still prefer to try disabling the WiFi, let me point you and cite parts for this other forum thread:

balenaOS uses NetworkManager to manage the connection. The documentation explains in detail on how you could manage the connections. If the documentation is not helpful or lacking, your feedback is appreciated.

As detailed in the doc, once you ssh into host OS, you could edit NetworkManager’s configuration to change the connection to be ethernet only (or in other ways). To edit the file:
vi /etc/NetworkManager/system-connections/resin-wifi-01

Before you turn off the wifi connection, make sure you have other ways of accessing the device via a direct physical connection or another networking setup in place (like ethernet conection). Else, you will lose remote access to the device.

Then also use NetworkManager’s nmcli to disable the wifi if you don’t want to persist the configuration:
nmcli radio wifi off

Kind regards,
Thodoris
