Realtek HD Audio Sound Keeps Breaking

I'm having an incredibly frustrating issue with my sound where it randomly, for no reason that I can find,- stops working completely. I've reinstalled my audio drivers, ensured they're up to date, I've run chkdsk's and done just about everything short of a reinstall, but no dice.

When the audio breaks, spam-disabling and re-enabling the speaker in Playback devices will occasionally solve it for a few more minutes before it eventually breaks completely again, forcing me to reboot. This happens every once every 20-40 minutes, with no pattern or any trigger that I've been able to find.

The bars in the volume mixer are still moving as if sound is playing, the in-built Windows 10 audio troubleshooter can't find any problems, and my music player keeps playing music etc. as usual. The only indicator that the sound has stopped working (beyond the obvious lack of sound) is that youtube videos get choppy and start stuttering.

Here is what my Device Manager shows in sound and audio; [URL] .... Note that disabling/enabling High Definition Audio and Realtek Audio in various combinations does nothing to fix the issue.

Here's my dxdiag log [URL] .... I'm using Windows 10, and my motherboard is an Acer FMP55
