Hi guys, I got issue with Dell Inspiron 7570. From the moment laptop displays POST screen speakers starts making crackling noise in periodic intervals (cca every 2 seconds). I tried replacing audio chip and replacing speakers, different BIOS, updated BIOS to newest version, nothing helped. I know these machines had some software issue with speakers crackling, but mine become permanent hardware issue. Audio chip is bit warmer than it should be but nothing special (around 37-38 Celsius). I couldn't find any short out there, audio jack is good, speaker jack is also good, really got no idea what could be causing it.

Any ideas would be very appreciated.

Thanks .)

maybe a problem with the connector?

Connector is OK, think some small capacitor could be shorted or faulty diode but cannot find it anywhere.

you need a tool like ST5S
