Hi, I write from Italy, so excuse me for my bad english.
I bought a Z87X-D3H on October 2013. For the first month everything worked normally, but now i have this problem:
From the speakers I can't hear anything !! I tried with other speakers but nothing changed. If I turn up the volume to max and play an mp3 I can hear a very very low sound only from one speaker !!
All drivers are installed !! I tried a format and a clean install of Windows 7 x64 with reinstall all drivers but nothing changed !!
If I plug an HDMI cable to motherboard and select the tv over hdmi as "default output" for audio, I can hear sound normally from tv's speakers !!
I tried a BIOS update from F5 to F7 but nothing.
I tried also to umount and then remount the mainboard from the case but nothing.
So, only the audio over 3,5mm jack have the problem !!!
What can be ?
