Sony z1 audio board questions

Hey guys,

My audio disappeared and stopped working. it no longer shows in the device manager. installing the driver does nothing. my audio icon has a red x on it and when i click it it wants to detect problems (it doesn't work). what should i do? how should I diagnose the audio? I feel like this is hardware problem as it just happened out of the blue.

I am running Windows 8 (and have been for a while) using Andrew08's guide located here

I updated the bios
chipset drivers
took it apart and unplugged and replugged the audio board
started in safemode
restored to a system restore point from a month ago.
*CLEAN INSTALL (per andrew 08's guide) still same problem. this is a hadware problem.

none of these worked.

see as I think it is a hardware problem, does anyone know if this audio board has the actual realtek chip and not just the i/o? (so if i swap it out i will have audio again)

update: found this waiting for a reply from MikjoA. or anyone who knows!

Thanks guys!

Update:
see last post: Replacing the ribbon cable model number FPC-197 1-881-486-11 fixed the issue.

MikjoA I tried to message you back but your inbox is full.

 

I just swapped the audio board and it still doesn't work. i kept the new one in just in case. can anyone help with diagnosing what the issue is?

thanks

 

did a clean install after the board swap. still nothing.

 

still stuck, any help would be great! thanks

should i post this in another thread somewhere?

 

if you already swap the board, let try swap the cable if you can.
in addition, do you see audio device in Device Manager?

 

unfortunately, I don't have an extra cable. The audio device does not show under the device manager. however the USB power and the HDD that use the same cable are functioning properly.

 

Usb power and HDD are working properly doesn't mean the cable is fine since data line for each device is separately. It could be data line or power line for audio board on the cable has been broken.

do cables like that just stop working? is there anything I can do to diagnose the problem? should I return the audio board i purchased?

for future reference the VPC-z11 cable for the ODD/HDD and audio+USB mini board is FPC-197 1-881-486-11

thanks

 

I just changed the ribbon cable. audio is working again! thanks a lot for everyones help and suggestions.
