What service to use for NUC speaker

[cicinovec]

Hello,

Recently I have migrated from Raspberry PI to NUC with HA OS. When I start the NUC, the internal speaker welcomes me with Hello, how can I help you This leads me to conclusion, that HA already use this speaker.
And now the question is, how can I use it for notify or TTS service? Anyone an idea?
I see the soundcard in HW info

Unless you instructed HA to do so, it very likely comes form somewhere else.

Is there a way to find out where it comes from?
