hi all - purchased Silverstone FP32 http://www.silverstonetek.com/products/p_c...=fp32&area= provides front panel support for USB and Audio (line out and mic) . unit comes with two connectors for audio, azalia and ac97. motherboard is Abit AN7 with onboard ac97 . stupid me plugs the azalia connector into the motherboard header (both connectors are the same block, 10 pin with one hole covered over so it only plugs in one way) and start the computer. well of course there is no sound as the AN7 does not support HD audio(azalia). i shut down and change to the ac97. start up and still no sound. remove ac97 connector and replace jumpers on header and there is no sound from my back panel. ?@#*. uninstall and reinstall the Nvidia audio drivers still no sound. windows lists nvidia driver as playback device(control panel) player doesn't complain about audio problem and equalizer spectrum shows it is playing but no sound from speakers (and yes they are plugged in with volume up on master, player, and speakers and i tested the speakers on another machine - they work).
the pin out on the azalia and ac97 are very similar so correct me if i am wrong but i don't think i created a short with the azalia connector.

Q. could windows have recognized the HD audio connection and somehow stuck with it?

in bios i only have the option to enable or disable onboard audio so i disabled onboard and tried a sound card. uninstalled nvidia drivers and installed creative drivers and that worked. i have sound through the sound card.

Q. how the hell did i ruin the onboard sound and can it be fixed?

here is the reply from SilverStone, which i must say was very quick:

Hi Caperdog,

there is now way you can damage or cause a conflict by connecting the wrong plug on the Audio port of your motherboard, you may just try to enable the onboard soundcard that way you enable the front audio ports, also if your sound card has the option for front audio you can also connect the front audio port on the sound card

Thank You

Joel

more banter with joel:

hi Joel
thanks for the fast reply
onboard audio was enabled in bios when i first installed FP32. your saying i should try it again,which i will but probably not tonight. (hockey game)
is there a possibility of a short in the FP32 cable that could cause the motherboard grief ? like conflicting signals or voltages ? understand i am not trying to lay blame i just want to fix the problem. i have the product in another computer and it works fine.

thanks
Caperdog

Caperdog,

I don't think there was a short there is no reason for that, what I'm thinking is that whenever you install a pci sound card the motherboard will dectect it and disable the onboard card

Joel

------------------------------------------------

Joel,

the pci sound card was installed as a last resort because onboard sound, when enabled in bios just would not work. onboard sound was disabled in bios before installing the pci sound card. this is pin out on motherboard


pin 4 would be positive voltage(i am assuming this because it is not called ground) deliver to the presence contact on the azalia. which wire would that voltage return on ?


i removed pci sound card to try it again with just the jumpers on the header and enabled in bios (as it was when it worked) and there is still no sound being delivered to speakers. audio controller is listed as working in device manager and no IRQ conflicts. player plays the song and the equalizer spectrum and vu meter shows sound is being generated but it is not making it out to jacks in the back or front panel.

silverstone tech speaks again:

Hi,

so the rear audio ports are working? if yes what software is your motherboard sound card is using? realtek? if yes all you have to do is on realtek setting you need to disable the front auto sensing or auto detection

Joel

--------------------------------------------

hi again

no the rear audio ports are not working . i will look for realtek settings athought i' m not sure where to look, they are not in bios and it was nvidia software that was controling the onboard sound.

i will give this up now as it seems to be a lost cause. it could be that it was coincidence and it was time for the onboard sound to die.

anyhows the pci sound card is working so my daughter is happy and in a year or so i will remove the motherboard to see what is burnt.

if the mods would like to scrub this whole solo exchange its ok with me.

I'm sorry for no responses
Your problem has me stumped. I would have to say it's just coincidence

thanks for input garmanma

the one good thing about all of this is it brought me back to Bleeping Computer, where i answered some questions and hoped that i helped, and even stuck my nose in where it didn't belong. all the while the responses i've read were direct, honest, polite, and knowledgeable. some with a nice side order of humor.

Hats off to you all!
