Windows 7: conextant internal laptop soundcard problem

conextant internal laptop soundcard problem

The problem occured last week while playing some moonbase alpha, my speakers basically cut out while playing however windows believes it is still outputting sound to them, if i plug a jack into either of the speaker or microphone jacks and remove it the problem is instantly fixed and sound continues as normal for up to around 10 minutes when it happens again.
I can fix it again for 10 minutes by switching from the playback tab to the recording tab in the sound properties menu, i have tried reinstalling drivers that came with my laptop and drivers from other sources, i have tried drivers that are older than mine, i have also tried using the default driver windows 7 assigns it "intel HD audio"
the device is shown as conexant smartaudio HD
I have tried my volumes, my balance and i have played about a little with the sound properties and with the smartaudio application.
I have also tried restoring to an earlier point before the problem happened and before i even installed moonbase, windows troubleshooter reports no problems.
Specs and dxdiag are below,
Many thanks,
Ben.

None of that diagnosiic data is needed. Just fill in the information for the "My System Specs".

First suggestion, go to the Device Manager and uninstall the sound device there and then restart the PC and when Windows starts it will detect and reinstall the sound. If there is a corruption between Windows and the sound card this will fix it.

In the Device Manager, RIGHT click on the entry for the Sound Device, then LEFT click "Uninstall" DO NOT check the box to uninstall the drivers. Then restart the PC.

Are you using Conexant drivers from the PC/Motherboard vendor? if not that is the next suggestion. Non-vendor drivers either do not work or do not work correctly in many cases. I know you have said you tried other drivers, but if they were not the Pegatron provided drivers that can be an issue.

There could also be other problems such as a hardware problem or a Windows OS problem (if its a Windows problem it will take a complete reinstall).

I was dreading a reinstall, i am using the drivers provided with the laptop, i did try some from other sources but ultimately i always reinstall the vendor supplied drivers after a negative outcome.

A reinstall is the last resort, if nothing else works. I don't like to do it either and only do reinstalls (I do part-time PC repair) at clients when absolutely needed.

There could be some program that is loaded at startup that is causing the problem. Look at what is loaded at startup and what is in the "notification area" (Used to be called the sys tray) in the lower right of the task bar.

This is one of those things that can be difficult to find, assuming its not a hardware problem.

Hey there, I just wanted to say that I seem to be having the same problem. I've taken to watching films on my laptop with my finger hovering over the mouse button in order to mute and unmute the sound as quickly as possible This is just an impression I have, but it seems that the amount of time between when I restore the sound and when it cuts out again decreases in proportion to both increasing volume and increasing amount of time that audio has been playing.

Like bv2490, I have reinstalled the driver and restored to before a time when the problem occurred. Any further suggestions, aside from a reinstall?
