airdroid plays music automatically after web connection on Android 6.0

I updated my phone to Android 6.0 recently. When I open airdroid and use web browser to connect to my phone via my local wifi, airdroid starts to play music automatically and it doesn't stop even I exit it, until I use app management to force close it. I have tried to clear software data to reset it to default, but it does not work. Does anyone else meet this problem?

ok, I found the result. When I tried to connect to airdroid, there was a ring tone which was the same as notices, but after I updated the OS, there might be some data error during the update , and this ring tone became a long music in airdroid ,(but it was ok on other notices). airdroid would play it completely and i couldn't stop it until it finished playing. I went to the system settings to reconfig my ring tone of notices, kept the settings as it was, just clicked ok again. It's fine now.
