I have a HP m8000n computer. I have a non-OEM video card that has been installed for over 2 years and had no issues during that time.
A couple of weeks ago, after a reboot, I get the error message about "no audio device installed". Tried rebooting, going thru all the recommended actions to correct the issue from checking the BIOS, uninstalling and reinstalled both video and audio drivers, and nothing worked.
After I couldn't take gaming anymore with no sound, I brought my old computer out of storage and set it up to play, and transfered the video card to the old computer....blah blah blah......I set up the new computer a few weeks later for my wife to surf the web, and upon rebooting, the sound has returned....
I transfer the video card back to the new computer, then in the middle of gaming, the sound went out and the computer started to lock up. After reboot get the no audio device error again. After 3 more reboots I finally get the sound back. No issues for a week, then sound goes out again.....(this frustration was repeated over the next couple weeks). I got tired of it, and removed the video card, and the sound came back. Believing the video card was the issue, I reinstalled a different and older non-OEM video card, and had no issues....for a week. Sound issue came up again.
When the sound goes out now, I can reboot a few times and the sound will come back sometimes, but if I simply just remove the non-OEM video card and either use the onboard card or install a different non-OEM card, the sound comes back for a while, but the same issue keeps coming back.
I have tried:
1. uninstalled the non-OEM video cards numerious times, rebooted with the onboard, then reinstalled the non-OEM cards.
2. Uninstalled and reinstalled audio drivers numerous times.
3. Updated audio drivers numerous times.
4. Reinstalled original drivers for both audio and video.
5. All three Video cards were NOT overclocked, but seemed to run a little warmer than before.
6. I have gone thru many of the other threads and tried some of the suggested remedies, but none of them have permently fixed the issue.
Any insight would be greatly apreciated.

I'm wondering if you could have a software conflict with the games you are playing or some other app that is causing the Windows Audio Service to crash. You may want to google your game titles and see if there are any known issues.
Have you tried updating your sound card driver using the original manufacturer's driver? Your PC has Realtek ALC888. Go to http://www.realtek.com/downloads/ and select "High Definition Audio Codecs".
Also, here are few HP support documents that may help:
