TTS issue within DLGaS (French LP)

[CarolineRey]

Can't hear TTS within the DLG in demo client (TTSaaS only tab works fine). French language.
Project: 14901 (TTS modality is on in my project)

I do see the following error:

Any idea?

Thanks.

To verify...

• What experience simulation is selected?
• Did you provide the appropriate channel name that has the nlg message segments?

Hi Nirvana,

Simulate Experience: IVR: Voice & DTMF Input with Voice Output.

As regards channel names, I tried Default, Digital VA or IVR/Voice VA (channels that I have defined in my project and have TTS modality on). Can't hear any voice.
