This is a problem that has come up recently. No changes done in audacity but there was a Windows update in the last week.
The exported process from Audacity (Tried MP3 & Wav) is error free and the same as I have used for a long time.
The exported file is perfectly audible using microphones. But file is very distorted and almost inaudible over device speakers.
This problem is NOT only in my laptop. I have transferred the exported file to my friends laptop (Via email) and also to my Mobile device (via WhatsApp). The same issue persists on all devices for both Wav & Mp3 files - Inaudible on speakers & perfect on Headphones.
I have already reinstalled LAME. Uninstalled Audicity & reinstalled (2 versions) - Problem persists!
