    Hi

    Hi. My SONY laptop model VGN-FW48E. Running on Win Vista s.p 2.
    Since last 2 days Audio stopped working completely.

    It shows the sound icon on start menu bar. But enables only HDMI audio.

    Speaker audio or Mic not working. Also i dont see any those devices on playback device tab.

    I downloaded and installed software driver for audio few times already.
    I updated BIOS as well.

    I tired one whole day doing these things and went to bed. Next day morning i saw Sound is working again. I thought everything is fine. But When i restart the Vaio, sound lost again.


    Finally I restored C drive using Vaio Recovery tool. Installed BIOS and Sound Driver from sony website.
    Still I managed to enable only HDMI audio. Im so so fed up with trying so many times.
    I can confirm nothing wrong with Sound card. This must be software/Driver or OS issue as i can see. But i dont know how to fix.

    Please tell me how can i get my audio back.


    Thank you in advance.

    Rayan

    First thought, hardware fault.

    With that said, what is the audio chipset status in Device Manager?

    Under Sound, Video & Game Controllers, i can see only High Definition Audio Device.

    Before this happed i noticed Realtek Audio Device was also there.
    I downloded and install driver from sony website. But still it enables only HDMI audio. Not speaker audio.
    After hibernating from Night to morning, it worked once in the morning/. But again sound stoped working
    giving "Sound Applet is not Responding."

    According to the specs, it uses Intel HD audio: https://www.sony-europe.com/support/en/product/VGN-FW48E_H/specifications

    So I don't know that you should be seeing "Realtek" listed in the audio section.

    Randomly working and not working is typically a sign of a hardware fault. Sometimes you power up or reboot and the hardware functions properly, is recognized, and works. Others times it doesn't work at all.

    I assume you are referring to the laptop speakers. If so, have you tested the headphone output?

    Yes Im referring to internal laptop speakers. I already tried with headphone output. But result is same. Audio started working in the morning when i turn on the Laptop. This happened 2-3 mornings. But after few mints volume control friezed and go the error "Windows shell common dll not responding/stopped working". So when i restart the laptop, it starts without audio. So i guess sound card is working fine. Based on above situation do you think this can be hardware failure.

    "sound applet" or "windows shell" could indicate a Windows fault. I don't know of a fix.

    You could try using a Restore Point to a time before the trouble began.

    Aside from that, my first thought would be a fresh install of the OS. Before that step, you could try manually reinstalling SP2, and then ensuring all of the drivers are up to date.
