Hi there, Is there any SER8 bios update to solve the headphone output issue with Linux? HDMI output , bluetooth speakers working good but when using headphone output no sound at all with Linux. Windows 11 works ok.

Hello, Please send a complete screenshot of your current BIOS version page. Here is a link on how to check the BIOS version： https://url.bee-link.cn/EqEu After you provide the current BIOS version, we can determine which one your BIOS is suitable for? Best regards! Wendy Customer Support

Hi Wendy, Here I attach a BIOS screenshot as you mentioned. Thank you for your interest. Farewell.

SER8 8745HS Linux headphone output issue

It works well for me with Ubuntu. I used 20.04 and now I have 24.10. at least front output but the sound level is very low, need to set max volume for reasonable sound

Even putting it to max volume is too low despite you put an EQ or maximizer plugin.
it’s obviously that doesn’t work properly.
Some people reported having that issue since they update their BIOS to the same one that I have in my SER8 8745HS.

Hello,

Your BIOS version is already the latest, so you don’t need to update the BIOS version again.
Which version of linux are you using?

Have a nice day!

Hi there
Does it happen if in windows ?

Hi,
Windows 11 works fine.
Is just Linux, making a search on the internet, here I attach a thread exposing the same. Someone of your crew said that there will be a BIOS update soon, it was on January 6.

Hello there,

Your bios version is already up to date, and there is currently no updated version.
May I ask have you tried other versions of Linux?

Best regards!

If it works in windows, pretty sure it is not a bios problem but a linux driver problem… try a recent distro like Linux MX AHS, once installed update kernel to latest using their MXPI tool and update all packages, just to check.

Also disable Fast Boot in BIOS

I’m having the same problem on windows. I’ll check the Fast Boot option in the BIOS.

Hi there .
Please try some solutions here :
1.CLR CMOS
First, please unplug the power supply and HDMI cable.
Secondly, Please hit the “CLR CMOS” button/hole for about 10 seconds.
For some models the CMOS hole could be in the Audio port .
Please wait until 10 minutes later (THIS IS VERY IMPORTANT),
Then plug the power supply and HDMI cable back in, turn on the PC again,
once turn on the PC, you will need more than one minute to wait for the PC to enter the system.
See if it works. Please try few more times.
