Audio Import error

Since updating to 5.1, audio does not import correctly. Shows as 'Unspecified error during import of AudioClipAssets/_Audio/Groan.aiff.
Tried different formats such as .wav etc. Same issue. Anyone had the same problem?

Got the same problem. Seems a lot of people are having the same issue with 5.1. Is there any other fix than downgrading?

Thanks for the reply. So its a unity issue. They need to solve this, I will post a bug report.
