I was playing far cry 4 the cpu temp was above 75 °c
Then the game was freezing so i had to cut the power off by disconnecting the power cable
The problem started when i turned the system on again . There was no sound at all not even at the welcome massage
So i tried changing the sound output and changing hdmi cable , change into av cables , i evan changed the tv but i had no luck
Hope someone can help.....
Note: i have ps3 slim 320 gb
A 4.84.1 rebug rex cfw
 
The PlayStation3 doesn't have a separated Audio DAC, is all carried through the Panasonic MN86471A HDMI Encoder for Digital Sound Signals, and the Sony CXM4027R AV Encoder for the Analog Signals.

Usually the Panasonic MN86471A is the suspect as, on models above CECHG, Sony switched the IC Encoder from Silicon Image/SCEI 0735 to the Panasonic MN86471A, which is the same IC Encoder used on the PlayStation4, and these are prone to go bad, but it seems they represent a higher failure on the PlayStation4, so if its partially working, you can get a picture but no sound decoding will come though.

But before, i would point the fingers to the IC Chip, as you mentioned that the MultiAV also doesn't show any sound, i would reinstall the firmware, or maybe before the reinstall, you could try Restoring The Database, perhaps there was a corruption on the Firmware level, and its nothing troublesome.

Thanks for your reply but i already tried rebuilding the database but it stayed the same so i thought the hdd may have bad sectors so i formated it and then reinstalled the rebug 4.84.1 rex yet the broblem remains
I think its time for me to leave it to an expert in the matter they will know what to do

If an "expert" is really an "expert", he will point out just one thing, the IC Encoder Chip.

By the way, did you tried fiddeling with the Sound Settings on the XMB?

Is there any audio circuit in PS3? Could there be any bad capacitors/resistors?

The Audio Circuit is the IC Chips themselfs, they have some tiny capacitors and resistors in them, ill take a picture of a COK-002 i have for spares as a reference.

Hi.

I got similar issues when both of audio from HDMI and analog port on my PS3 slim went fully busted. Then, i bought PlayStation Gold Wireless Headset to overcome this issues, however this headset is likely harder to find the new stock ones.

The other alternative way is to install HEN/CFW firmware with bluetooth audio output fully enabled which allows to listen audio from the console. However, this mod uses old firmware so may not tested on current 4.91 firmware version.
