I noticed that this issue is only happening in 8.11.x, I downgraded to 8.10 and the sound works like a charm
wget https://download.nomachine.com/download/8.10/Linux/nomachine_8.10.1_1_amd64.deb
sudo apt install ./nomachine_8.10.1_1_amd64.deb -y
in both cases the config server is the same.
AudioInterface pipewire
Also I noticed that NoMachine 8.10 is creating 3 NoMachine soundcards but 8.11 only create 2 interfaces, this is superweird but the issue is only happening in 8.10
