But with these drivers I can't use 'stereo mix', and windows will try to update them to Realtek again when I search for updates. The only thing that seems to fix the problem is uninstalling Realtek drivers and then installing Windows High Definition Audio drivers.

Looked into the BIOS for anything related to speakers or audio but couldn't find anything, didn't touch anything.

Looked into windows energy management settings to see if speakers were going into power saving or anything similar, but there's nothing like that there.

Tried uninstalling Realtek drivers and downloading them from HP site, official recommended drivers for my laptop, no help.

Tried uninstalling Realtek drivers and downloading them from Realtek site, those still make the problem happen.

Cleaned the drive and reinstalled Windows 10 from scratch, let it update and install drivers by itself, I didn't install anything myself.

Checked and reinitialized Windows Audio and Realtek Audio Service under Services, no help.

Checked every possibility under Windows audio device settings (changed bitrate, enabled/disabled exclusive mode, enabled/disabled spatial sound, etc) (option to disable hardware acceleration doesn't show in this computer), nothing helps.

Checking every possibilty under 'HP Omen audio control' (enabled/disabled enhancements, enabled/ disabled multistreaming, enabled/disabled mic noise cancel, etc), nothing helps.

Contacted HP Support Chat: HP Tech updated my BIOS and reinstalled my drivers but it didn't fix the problem.

This doesn't seems to happen 100% of the times, but like 80% to say the least. This is very annoying because I have to constantly rewind every new video I watch, and I work with music and my notation software will do the same thing, no sound for the first second or two after the computer has been silent for half a minute. This happens either with the computer plugged to power supply or with battery mode. Then it will happen again, when I want to play something, it will start to play muted for the first second or two, then continue normally. Then the sound is fine, until there's no sound for about 30 seconds. Whenever I want to play something with sound, no matter if it's a YouTube video on Chrome, Edge or a desktop app, about the first two seconds of sound will be silent, thus missed, so I have to rewind or replay whatever I was playing to hear it again. This laptop is new, installed a few days ago with W10 Home 64.
