Hi there,

Take a look to the first post Yu`ll see there my BIOS version, this issue affects to every Linux version, headphone output sound is too low and it happened since Beelink updated the BIOS to the last one.

    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!

          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.

                          Please also check if your BIOS is v29 the latest.

                              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.

                                        Can you send the latest BIOS version and manual to update it?

                                          Dear Beelink Support Team,

                                          I would like to sincerely thank you for your prompt resolution of the audio issue I encountered with the SER8. The latest BIOS update has successfully addressed the problem, and my audio is now fully functional on Linux.

                                          I truly appreciate the support and effort your team has put into resolving this matter. It’s clear that your dedication to ensuring compatibility and improving the user experience has made a significant impact.

                                          Thank you again for your timely assistance and for fixing the issue that was preventing the BIOS from properly enabling audio on Linux.

                                          Best regards
