My Asus Essentio 1330-05 desktop PC, bought locally in desperation two years ago because I didn’t have a working computer with which to order parts, has been a disappointment. Cheap DVD drive and power supply (both had to be replaced), no case fan (I added one), poor air flow, and a graphics card fan that frequently clogged with cat hair and overheated. I finally bit the bullet and bought a new case, a Corsair Vengeance C70, which is well-ventilated, currently runs three case fans, and is a pleasure to use. I moved the MB, CPU, GPU, PSU, HD, and the DVD drive.
Everything works fine, just as it did in the old case ... except that I can’t get the sound to work.
I’m running Win7 64-bit.
* The Device Manager shows two ATI devices and one VIA device as working properly.
* The “manage audio devices option,” on a different part of the Windoze control panel, shows SPDIF interfaces TXD and TXI as ready. Speakers are shown as connected to the VIA device. ATI DP and HDMI are shown as NOT PLUGGED IN. Speakers are selected as the default device.
* VIA HD audio deck control panel shows the speakers as the default device and the sound turned all the way up.
I checked the connection from the speakers to the motherboard; that's solid, just the way it was in the old case.
I cannot figure out how the sound was wired in the old, original case because NONE of the connectors in the old case are labeled. None of them look like standard connectors.
The new case came with a blue connector labeled HD audio, which I plugged onto the only pins on the MB that match the configuration, which are labeled AAFP. I believe that this controls the audio jack on the front of the computer. I would test it if I had headphones, which I don’t.
There are three pins on the MB labeled SPDIF OUT, with nothing connected. There are also four pins, a few inches to the left, labeled speaker (on the system panel connector). Perhaps I need to connect the SPDIF OUT to speaker? But that would seem odd, as the system panel connector controls the front panel on the computer, not necessarily the audio connection on the back of the computer.
I finally extracted the motherboard manual from Asus. The motherboard is the M4A78LT-M. But the manual is no help.
Do I need to connect anything to SPDIF OUT? If so, what and how? Or is it just a question of reconfiguring something in my system? I wouldn’t think that anything would need to be changed, as it all worked before the transplant.
Any help gratefully appreciated.
