Hi aderkachoff,
Welcome to Sony Community!
We're sorry to hear that. by the way the PCG-61315L is the chassis number of the computer. Is the model name VPCEA4AFX (i found this to your other post)? When was the last time that the audio works? Was there any change on the device prior to the issue?
Hereis the link for your troubleshooting guides.
I hope this helps.
Regards,
Jen
