Yesterday, as I was watching a Youtube video, my laptop restarted randomly, displaying the error "APC_INDEX_MISMATCH". After it restarted, the sound on my laptop stopped working (both the headphone jack and the laptop's speakers), and I can't seem to figure out why. When I play music or a video, the computer shows that sound is playing through the speaker levels, but nothing comes out. I've run the Windows troubleshooter on both the speakers and the headphones, updated the driver software for my headphones, and disabled and enabled both the speakers and the headphones, but nothing seems to work.
I have a Lenovo Thinkpad 11e (around a month old) with Windows 10 on it.
Anybody have any suggestions? I can't seem to find anyone who's had the same error as me.
