No Sound on Phone Calls after using Bluetooth

[Rirruto]

I've just encountered a strange and frustrating issue that began a couple of days ago on 7/12. I have a Galaxy S4 running 4.4.2 and a 2010 Nissan Altima. I've had my car for 4 years and have never had this issue with any of my phones until this past Saturday so I am convinced it is my phone that is the issue. The Bluetooth pairing will connect without issues (indicator on both phone and car screen indicates so) and I am able to make/receive a call with sound successfully for one time. If I a make or receive a second call, there will be no sound both on my end or the caller on the other end. I know the call connects since the call timer starts on both my phone and the car screen as well as on the caller's phone (tested out with my wife's phone while in the car). I will not even hear a ring tone, the call will just connect without sound. Even if I disconnect the Bluetooth connection, there will not be any sound coming from my handset and the caller on the other end cannot hear me when trying to perform a call. The issue can be temporarily fixed with a phone restart. After making one successful call after a phone restart, the no sound issue will return. I'm not sure what to do at this point. I've re-done the phone pairing with my phone and car but the issue resurfaces. I see somebody posted a very similar issue on a different website on the same exact day I started getting the issue (Can only hear phone calls on Bluetooth) so I am wondering if we got some sort of app update that has started to interfere with Bluetooth connections. Any advice would be appreciated. Thanks.

Same issue here with S4 and Plantronics earbuds (my phone and wife's). Not found a resolution... you?

RESOLVED: Your comment in another section tipped me off. I, too, enabled "Ok, Google" from any screen. Disabled it and the problem is no more. Glad you got yours going as well!
