I just recently switched from a Samsung Galaxy Note 4 to a Samsung Galaxy Note 7, and like others here have expressed, I, too, am now having problems using headphones, the microphone and speakers with the Smule Sing app with my Note 7.
When I join an OC (open call), invitation, or try to start my own OC, the music tempo is slowed to a crawl and the audio is completely garbled and distorted.
However, if I listen to a previously recorded track or to someone's OC that I want to join the music and vocals sound perfect.
AND....... if I do try to record an OC (with all the garble and distortion) and then listen to the saved recording ..... The instrumentals now sound perfect (as they should have originally), but now my voice sounds like I sucked helium out of a balloon, and the tempo of my voice has increased!
On the first day I received my Note 7, Smule Sing was working perfectly (08/19 - 08/23)...but, once the newest update was automatically installed on 08/23 to version 3.9.3 all the problems began.
I have done the following to try and resolve the issue:
1. I have already checked to make sure microphone permissions are granted in settings, and still no change....
2. I tried I uninstalling and reinstalling the app.
3. I have tried installing older Smule Sing versions.
4. I have tried different headphones.
5. I have tried singing without headphones.
6. I have contacted Smule Sing support and submitted an example of a song I recorded for them to review.... I am awaiting their response and any resolution suggestions!
Thanks everyone! Hopefully we will all have a resolution soon and get back to singing
