I have a Lenovo laptop with W8 not 8.1. I am not getting any sound and can't seem to find fixes for W8.
The speakers were working fine until my daughter used my computer a few days ago.
Have you tried a simple reboot?
Is the Volume perhaps muted?
If you have checked those items then a system restore might help you.
Here is a link that might be useful: System restore guide win 8
Thanks. I tried the first two but didn't think of a system restore. Will try that.
