NAD C338 / nadtcp doesn't work

Configuration
1

Hi,

I have a NAD C338. I have various ways of controlling this device, but my biggest gripe about the device is that it won’t let me switch directly to an input in any way. I’m not sure if Home Assistant does this, but it seems worth the try.

I’ve activated my NAD by adding this in my configuration.

media_player:
  - platform: nadtcp
  host: 192.168.2.7

This causes the NAD amplifier to show up in my HA. Nothing works. The IP is confirmed to be good via my NAD app.

The docs are unclear about C338 support. Is this the issue maybe?

Thanks for thinking along in advance.

update: Here’s the logs
