Hi,


I recently completed my first HTPC build and everything seems to be working great except I don't have sound.


These are the components used:


Mobo: ASRock A780GXH/128M AM2+/AM2 AMD 780G HDMI ATX AMD Motherboard

CPU: AMD Athlon 64 X2 5000 Brisbane 2.6GHz Socket AM2 65W Dual-Core Processor

RAM: G.SKILL 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit

PSU: OCZ ModXStream Pro OCZ700MXSP 700W ATX12V V2.2 / EPS12V SLI Certified CrossFire Ready 80 PLUS

HDD's: 2x Western Digital Caviar Green WD20EADS 2TB SATA 3.0Gb/s

4x Western Digital Caviar Green WD10EADS 1TB SATA 3.0Gb/s

Monitor: Sharp Aquos 40" LCD HDTV Model #LC40E77U

OS: Windows 7 64bit

DVD: Pioneer 20X DVD±R DVD Burner Black IDE Model DVR-116DBK

Audio: I'm using or hope to use the onboard audio.


I've connected the HTPC to the TV using a HDMI/HDMI cable. I get a great picture but no sound. I made sure I installed the Audio drivers for Windows 7 64bit which I downloaded directly from ASRock's site. Reading through the manual for the TV I found these instructions:


Connecting a PC:

When connecting to a PC with an HDMI terminal (INPUT 5, 6, 7 or 8) {It then shows a picture of an HDMI/HDMI cable connecting between the PC and the TV. I'm connected to INPUT 6, I have an Upconvert DVD player currently in INPUT 5 though if I get the sound working it'll be removed}

Then it says:

When connecting a PC to the INPUT 6, set "PC Audio Select" to "Input 6 (HDMI)". (See page 25.)


I go to Page 25 and this is what it says:

PC Audio Select

Determines whether the AUDIO terminal is used for INPUT 4 (PC-IN) or INPUT 6 (HDMI).

Input 4 (PC): Select this item when the audio signal is input via the INPUT 4 (PC-IN) terminal using an analog RGB cable.

Input 6 (HDMI): Select this item when the audio signal is input via the INPUT 6 (HDMI) terminal using an HDMIDVI conversion cable.

Note:

When "PC Audio Select" is set to "Input 6 (HDMI)", sound will not be produced if you use only an HDMI-certified cable to connect HDMI-compatible equipment. To produce sound, you should make an analog audio connection.

If you want to connect HDMI-compatible equipment using only an HDMI-certified cable, set "PC Audio Select" to "Input 4 (PC)".


So if I'm reading this right does that mean if I'm going to use INPUT 6 I need to switch to a HDMI-DVI cable? Or does it sound like I could save myself a bunch of trouble and switch to INPUT 5, since I'm planning to get rid of the DVD Player anyway once I get the sound working?


I'm currently at work, plus as of this morning I had no power thanks to a downed power line so I can't just test the INPUT 5 theory. Any suggestions would be greatly appreciated.


Thanks,


Beth

Make sure you look under playback devices (right click the speaker icon in the taskbar) and verify the HDMI audio device is set as default.
