"Slowed down" recordings with Alesis io2

I’m using Lenovo V50 Win10 8Gb RAM With an Alesis io2
I select it in the Windows control panel;
Audacity (2.4.1) recognises it
I start recording (mostly voice)
When I play, the voice is slowed down, I presume due to sample rate

Someone can help me?

Thank you in advance

For future recordings, try changing the default sample-rate from 44100Hz to 48000Hz …
