Today I tried to turning on Startup Sound in BIOS and got a somewhat terrifying experience.
Well, saving settings end exiting I heard an impressive "Intel" sound. However, in Windows I realized that all sound devices are gone. Here is the screenshot from DevMan.
There is only "High definition Audio Convertor" with an exclamation sign in System devices.
Several reboots did not help.
However, shutting down and powering on I got another piece of fun:
I asked Windows to restart, went to BIOS and turned the evil sound OFF.
And things got back to normal: I booted swiftly and sound devices returned:
Thank you for joining this Intel Community.
In order to gather more information about this issue, I will attempt to replicated it. My recommendation is that you can follow these steps:
1. Run the Intel® Processor Diagnostic Tool and attach the report.
2. Load default settings in BIOS.
3. To check the Event Log, please follow this path: BIOS > Advanced > (Lower Right Section)
Hello Wanner G,
1. Intel® Processor Diagnostic Tool - attached.
2. I always load default settings after BIOS update and then (after successful reboot) change just some of them (like Power LED color). Anyway, after turning OFF the Startup Sound in BIOS, things got back to normal. I'll just avoid this option in the future.
3. Thanks for the info regarding Event Log.
What BIOS revision are you using? I tried this on BIOS 0042 and did not see any issues in Windows. I am using Windows 10 RS3 (16299). If you are using RS4 (17134) that may be why you are seeing this. Have you updated to the latest drivers?
Are you using the front or back audio port?
The Thermal Trip error may be a false positive. I would be very surprised if one of these Atom based systems ever overheated. They have such low power uses.
You can see the Event Log in the BIOS on the MAIN tab next to the clock.
I have BIOS 0042, OS build 17134.191., Realtek Audio 184.108.40.20643, Intel UHD Graphic (includes HDMI Audio) 220.127.116.1194.
When Startup Sound in BIOS was enabled there were NO sound devices in Windows AT ALL. Therefore there was no sound on the front, on the back and on the HDMI.
I'm pretty sure that the Thermal Trip error was false positive. I ran across another thread . It took Intel half a year to fix it.
Thanks for the Event Log hint. It does show the Thermal Trip error.
If I understand you right you also tried to turn on the Startup Sound in BIOS, and it played, and you did not have any negative effects like Thermal Trip error or loss of sound devices in Windows. Correct? Then it it implies that it is only my system, which suffers from enabling Startup Sound in BIOS. It's not big deal by itself, but it may indicate that there are some nasty problems in BIOS.
Strange I didn't see the same thing you did after enabling the Startup Sound. Other than getting the startup sound playing twice with the 2nd sound garbled. Only other thing to try is different memory. I am using (1) Adata 4GB 2400MHz DDR4 SoDIMM in my NUC. Make sure you are not overclocking memory.
Thanks for your reply. I have 2x4GB Crucial CT4G4SFS824A SODIMMs which seem to be Intel Validated. And I have not experiences any inabilities while in Windows. Most of my glitches were in BIOS or closely related to BIOS. I suspect, my BIOS somehow got corrupted and BIOS updates (through F7) or even recoveries (through Power button and F4) can not fix that. Needless to say, I always reset BIOS defaults (F9) after every update.
By the way, can you see POST Function Hotkeys on the NUC splash screen (e.g., "Display F2 to Enter Setup")? Initially I had them, but very soon they were gone. Then after some BIOS update they appeared again, but shortly after that disappeared.
You are right, it's SSD. It is an interesting point. As I recall, there is an option in the BIOS to delay the boot process. Maybe enabling this option could eliminate some strange effects.
By the way, what do you mean by the "yellow bang"?
