Hi All,
Basically I installed Mac OS X 10.11.2, followed the guide in this forum (Dell Latitude / Inspiron El Capitan Clover Guide), everything works great at first, but after sometime - I don't know what exactly happened - right now my speaker do NOT have voice any more - but my headset is working fine - I mean I only can get voice from headset..
hope somebody can help here.
Thanks,
Jacob
