I got an email back from whatsapp about the noise occurring when using the app on the 8.1 preview, this is what they told me: Hi,
Thanks for your message. Sorry for the delay! We have received many emails recently, and we do our best to answer them all. Thank you for your patience.
Thank you for your feedback on Windows Phone OS 8.1.
Currently, WhatsApp doesn?t support the developer preview version of Windows Phone. Some features won't work properly.
Our OS 8.1 version is in the works, but we cannot speak for future timelines or features.
If you have any other questions or concerns, please feel free to contact us. We would be happy to help!
