I've just built a new PC:
- Intel Core i3 2100 CPU
- 4GB 1333MHz DDR3 memory
- Intel H67 Chipset motherboard
- Using the onboard graphics
- Using the onboard sound - Realtek* ALC662 audio codec
When playing audio only it appears to be OK, but when playing videos and games the sound will repeatedly cut out for approximately a second 2 or 3 times and then start again. When it does cut out we get a notification that the speakers have been unplugged (although clearly they haven't).
One piece of information we found indicates that it's related to CPU usage and this does seem to be the case. It would also explain why it's more of a problem when video is involved as the CPU is doing everything.
We've checked that we've got the latest drivers installed and if anything the problem seems to be getting worse.
Is the only solution going to be getting a dedicated graphics card?
This question doesn't answer the problem.
