I've got a huge problem regarding my hdmi audio in my intel dq87pg board. The setup is the following:
HTPC -> Displayport to HDMI Adapter -> Onkyo AV Receiver -> TV
OS is Windows 8.1, Graphic drivers etc. are the latest.
if the TV and the AV Receiver is on when I start the HTPC, everything works fine. But if it is switched off while booting, the computer does not find any hdmi audio device when the receiver is turned on later. The same happens when av receiver is on during boot and the sound works and I restart the AV reveiver or replug the cable in between.
I've tried nearly everything, different drivers, reinstall windows etc, but nothing helps. Does anyone have a solution?
I'll second this problem.
I use my PC as a HTPC which goes to sleep every night, but when it wakes up there is no audio. I noticed that the audio also disappears if the HDMI cable is unplugged then replugged.
When audio goes hardware devices shows a yellow exclamation mark by the audio driver.
Any ideas appreciated.
In this particular case, what happens when the AV receiver is not being used, so there is just a direct connection between the motherboard and the TV?
Keep in mind that with direct connection I also mean that no adapter or converter is being used, so the cable has the same type in both ends.
I have just tested this with a fresh install of Windows* 8.1 using 3316 drivers and an Intel(R) Desktop Board DZ87KLT-75K with Intel® HD Graphics 4600 and a ViewSonic Display the HDMI and tested switch sources, coming from sleep, turning the monitor on and off, and tried unplugging and plugging back the display and the audio keeps working normally.
Those having issues when using the TV directly connected, are you seeing any conflicts on Device Manager? Is this an upgrade or a fresh operating system install?
i'm sorry but I cannot connect my Samsung tv directly as the dq87pg board has no HDMI output. But the Displayport -> HDMI should be a level shifter only, the rest of the HDMI signal is provided by the board directly, so for the driver it should be the same as for a native and direct HDMI connection. However when the error occurs I see the error for the Audio Device in the device Manager. I have the windows event protocol for this device attached. But as a matter of fact, this event log does not add an error if the device is not working correctly. The errors happened after I tried to remove and ad the device again with the hope to repair it in such a way.
The error occured instantly in a fresh Windows 8.1 install without any windows Updates, just the current Intel drivers. The current windows updates don't change anything also :-/ Intel Display Driver Version is 3316, but the HD Audio driver seems to come from Microsoft.
Please try the driver posted here:
X32: Download Center
X64: Download Center
For this driver install follow the instructions on the following article to load the driver manually:
the likely reason you can't replicate it is because you are using a monitor. We are all using a tv, and most likely one that has HDMI-CEC. some sort of signal is being passed from the tv to the pc that is resulting in the intel audio being disabled. I am on a fresh install of Windows 8.1 (64). This wasn't an issue with my old htpc that had video and audio running properly over HDMI via the Radeon HD 4330.
Those drivers didn´t do the job.
I tried to use the hdmi for picture and pc soundcard for sound, via 3.5 jack to TV, but it won´t let me do that, the picture is fine but no sound.
Now I will buy an dvi-d to hdmi adapter to get the sound from the soundcard, not using TV sound. If that don´t work, I will wait for the win 7 intel driver.
