No sound from Sony VAIO VPCSE1CGX laptop
Hello, I recently purchased a used Sony VAIO VPCSE1CGX laptop to replace my old one, which the motherboard recently fried in due to an unfortunate run in with a water bottle. However, this used one I purchased was physically in better shape than mine, and so I just transferred my hard drive, backed up my data, and did a clean install using the Sony recovery software off a USB flash drive, completely erasing all data on the current drive and restoring it. When I restored, I noticed the sound did not function thru internal speakers, the headphone jack, nor did it function even when using an HDMI cable to a known good TV and using a known good cable. I then attempted to reinstall a clean blank copy of Win 7 without the recovery stuff, just in case the model was slightly different on this one. However, even after painstakingly updating everything, no such luck. The audio drivers appear to update successfully and there are no hardware issues reported. When I do sound tests, the windows Mixer shows level being sent to the audio channels but nothing is heard. i physically took the computer apart to look for loose or missing cables and ribbons, but everything is there and seated well. I'm stumped. Usually if there is some sort of sound card physical issues on the built in board, I thought the HDMI would at least work. Am I wrong here? Thanks!

Check really if the sound has been muted, I have had such issues once before I realized it. Otherwise the sound module is dead. Workaround a USB Sound card https://www.amazon.com/s/ref=nb_sb_noss_2?url=search-alias%3Daps&field-keywords=USB+sound+card
left Click on speaker icon then Mixer ( bottom right side of system tray ) and make sure all levels are High.
and also right click on speaker icon and select playback devices, make sure speakers are selected as output and as default.

Try to switch HDMI Audio Output as default audio in Control panel -> Audio. Right click and then "Set as default".

Dr. Klahn, this was my suspicion as well. I will have to double check the actual chips on the small daughter board on this computer, maybe I will get lucky and only have to replace the smaller board. But, in the meantime a USB soundcard might be the route to go.
otherwise -it may have been bad from the start
you can test this by running from a live cd - like knoppix, or installing ubuntu on the drive for testing
