Export cuts first few seconds of recording

Hi.

Audacity 2.2.1 on Windows 10 - Lenovo X1 Carbon 4th gen, Jabra UC Voice 550 MS

I record voice messages for our phone system. The Audacity project sounds fine, but if I export to MP3 (LAME) og WAV the first second or so is just silence. For example - the closed message starts: “We are now closed, Please go to our website…” and so forth, but the exported files sound “osed. Please…”.

I downloaded the software to my old iMac where the message exported complete and sounds fine. Problem is that I don’t feel like lugging it to work for this …

Any ideas?

Kind regards
Kjetil Thorstensen
