Hello everyone, Recently, the sound of my Toshiba Laptop (Running win 7 x64 Ultimate, model a205-s7468) went off all of a sudden. I've tried My computers > Propertes> Device managers > Sounds, video games controller to check if there is any problem with the drivers or update. But no "?" or "!" showed on Realtek High Definition Audio (nor any devices, everything seems to be up-to-date). I've tried many things but still, nothing worked out for me. Additionally, I ran a troubleshooting audio test but everything said no "no issue present". So I wonder what could be the problem? Could it be an internal damage to my sound card or any audio-related hardware? Any helps/suggestions will be appreciated.
