Wiim amp hdmi issues with Sony xf9005

[Tris]

Good evening,

I tried setting up the Wiim amp with my Sony xf9005 tv via HDMI today.

The amp turns on and off via HDMI.
Sound works with TV.
Randomly I get no sound with apps such as netflix or disney unless I turn off external speaker and on tv speakers then turn external back on and the sound comes from the amp.
The minute I come out of the app into another the problem reappears.
Turn off tv, back on, the problem reappears.

Using the supplied hdmi cable.

My much older Samsung TV has no issues at all, all apps, fire stick etc work fine, so im guessing it's a Sony tv hdmi issue...

Any help would be much appreciated.

Thanks - Tris

Others might have hands-on experience with Sony TVs, I can only mention general recommendations.

Apparently, the XF9005 is a smart TV, so first make sure that its firmware and all apps are up to date. HDMI CEC (aka Bravia Sync) is obviously enabled. Make sure that eARC (however this might be called in Sony speak) is not enabled, since the WiiM devices do support ARC only (but not eARC).
