I am at the end of my wits......
My daughter's DEL Inspiron 1110 notebook has stopped making sounds - through the internal speakers or through an HDMI output. This applies to all applications, including windows sounds. Its running 64 bit Windows 7.
Here is what I have tried to fix the problem
1. There is a speaker icon at the bottom right hand side of the screen, with an x over it. Hover over and see the message "no audio device is installed"...... I Right click and run the" troubleshoot sound problems" -> message - Hardware changes might not have been detected.
2. There is no "sound" line in the device manager screen.
Ran the "scan for hardware" changes.
3. Went to the DELL website and downloaded the audio drivers. It unzips files into a directory . Installshield wizard completes and I restart the computer.
(Realtek ALC272-GR audio card
Realtek High definition Audio Driver 22.214.171.12494)
4. Back to device manager
- Repeated #2
- Tried to load audio device drivers through "find legacy hardware" in device manager. (does not find an .inf file in the directories created by #3.
5. Ensured that the windows audio services were "automatic" and "started". Restarted them.
Symptoms have not changed from above - speaker icon with an x, no soud section in device manager, and most importantly, no sound.
6. Well - SYSTEM RESTORE. The system restore points are all after the date the sound stopped working.
7. My last recourse was to reinstall the OS. Several years ago (when my notebook was on warantee, DELL had to replace my hard drive.I suspect that the replacement drive does not have the correct restore partition, although the partition seems to have 85Meg of data. I tried the F8 (not CTL F11 on this model) and tried the factory restore. I get an "invalid parameter" message. Looking at bulletin boards, the general consensus is that the restore partition is not valid.
Can't even buy a restore disk, as there is no DVD drive on this machine.
Can anybody think of something that I have not tried? or do I tell her that audio is not going to happen any more :(
Thank you for the information / advice.
I installed Belarc and ran the analyzer. VERY interesting information.
There were no multimedia entries on the notebook. I ran it on another computer for comparison and found two high definition audio entries.
Does Belarc actually look at the hardware? or is it formatting the registry? If its looking at the hardware, then does this mean that the sound hardware is no longer working? If so, my only alternative would be a USB sound solution.
(The control panel / device manager does not allow the audio driver deletion, as it does not see a driver.)
