ser 9 max ai 7 H 350 sound problem

glnd

In my new ser 9 max ai 7 H 350 I cannot hear the sound. I see “2 - E2250 (3 - AMD High Definition Audio Device)” and “Speakers (3 - Realtek® Audio)” but can hear none of them. Volume is at max, and there are no warnings in device administrator. I’ve seen the drivers in https://dr.bee-link.cn/?dir=uploads%2FSER%2FDriver%2FSER9-MAX but I cannot install any new version. What’s wrong?

Hello there,

Could you please send us a picture of SN code(two lines) at the bottom of machine ?

You can try to clear CMOS : Please turn off the PC , unplug the power supply and HDMI cable , and press the CMOS pinhole for about 10 seconds.

Ten minutes later, plug the power supply and HDMI cable, turn on the PC again.

Here is the tutorial ：https://mega.nz/file/XypwTISY#DVT0BsjOgiPkZ-drQaj88JH9Z7f7qpKGP2E3nMHW8ms

I’ve sent you a private message

If I clear the CMOS, will TPM be right, the Windows installation will remain intact?
And if the clearing is succesful and I retrieve sound and keys to enter the BIOS (don’t function either! (though keyboard via dongle)), will I have to update the BIOS again?
Thanks

Hello there,

Clearing the CMOS will not cause any problems with the TPM, and the Windows system will still function normally.

If your machine successfully solves the problem by clearing the CMOS, you don’t need to update the BIOS.

Have a nice day~

I have reset the CMOS as indicated in the video, waited 10 minutes, and boot, but neither sound nor keys to enter in uefi at boot function. I don’t know if I have done it correctly, how could I check it? BIOS version should have downgraded?

Hello there,

Could you please tell me if your machine can still access Windows normally at present?

Would you like to try solving the problem by reinstalling the system?

Clearing the CMOS will not result in a downgrade of the BIOS.

Have a nice day~

Yes, I can access Windows normally, in fact I haven’t noticed any change in Windows nor BIOS after the clearing.

Would a reinstall solve the problem? I’d prefer not to do that… Maybe playing with controllers or any other feature could make a change?

Thanks

Hello there,

If you don’t want to try reinstalling the system to solve the problem, please try the following solutions:

Please go to device manager, uninstall the audio driver, then restart the PC.

Have a nice day~

Hi, I uninstalled the two audio devices that device manager sees: “2 - E2250 (3- AMD High Definition Audio Device)” and
“Speakers (3- Realtek® Audio)”, and after reboot they are both reinstalled again, but no sound is produced.
Also, I found now it problematic that, as I cannot also use F7 to enter boot menu in BIOS (or any other BIOS key), I cannot start from a linux USB to test the audio…

Hello there,

We suggest you try let stand the BIOS battery 1 to 2 hours to install back to try again, this is the tutorial: https://mega.nz/file/fz5HHaZQ#8HXWZaZD4SoqnkIuhsBeapSo6Kt4kzXNIyiTS1ORY8w
