E1705 with no sound even though everything looks good Windows 7
I recently installed windows 7 on my E1705. This was an upgrade from Windows Media Center. In both systems, I had no sound from this laptop.
I ran system diagnostics (F5) and the system sound tested ok in stereo.....(sound was strong and clear).....but failed in Mono.
I have the latest drivers installed and from all indications, everything should work.....no mute.....no x in device manager....speaker showing in taskbar....speakers picked as default...volume on..... but no sound. I am at a loss.....please help.
Thanks

It appears that the hardware has developed a problem. Have you tried listening through headphones or external speakers?

Good morning,
Yes. Plugged in headphones....no sound.....nor through the internal speakers. Although the speakers worked fine in the F5 diagnostic test in stereo mode. Failed in the mono mode......since everything we do is stereo......and the sound card works in this mode......???????

Sorry for the slow reply. I believe that you have a hardware problem and that you cannot fix this with a software solution. The only other thing that I can think for you to try is to use the basic Windows audio driver. Uninstall the Sigmatel driver in the device Manager and choose the option to remove it (or go to Start>Control Panel>Uninstall a program). When you reboot Windows 7 will install the generic driver. If the audio still doesn't work then you probably need to go to a hardware option.
(Or if you currently do not have the Sigmatel driver installed, then do so. Use the Vista version and install in 7 by using Vista compatibility mode.)

Thank you for you suggestions. I have tried both the window 7 driver and the Sigmatel drivers. (Sigmatel was Vista)
No difference. I do believe I have a hardware problem as well. I also think this motherboard has other problems and I am about to condemn it.
