Subject: Installed Debian 13.4.0 KDE Plasma on Edxis Chromebook LI9 but no audio
Good day from Singapore, I had bought refurbished/second hand/used Edxis Chromebook model LI9 with Intel Celeron N3450 processor, 4 GB RAM, 32 GB eMMC, Windows 11 Pro and Microsoft Office Professional Plus 2013 for SGD$85 at Siglap MRT station exit 2 TEL line on 24 Mar 2026 Tuesday at about 7.15 pm in the evening. The Edxis Chromebook has MrChromebox-2512.2 01/25/2026 UEFI firmware, which allows users to install operating systems other than ChromeOS, like Linux and Windows. At the top of the BIOS screen, it says "CTL Chromebook NL7/NL7T (Blacktip)". Initially I had wanted to reinstall Windows 11 Pro at 10.39 PM, but Windows 11 Pro installer says: "This PC doesn't currently meet Windows 11 system requirements Here's why: The PC must support TPM 2.0." I had no clue how the seller managed to install Windows 11 Pro on this Edxis Chromebook originally. I had wanted to reinstall Windows 11 Pro but couldn't proceed. I guess there is probably a workaround but I was lazy to find out how. At 11.28 PM on 24 Mar 2026 Tuesday, I had started installing Debian 13.4.0 KDE Plasma on Edxis Chromebook. By 12.31 AM on 25 Mar 2026 Wednesday, I had finished installing Debian 13.4.0 KDE Plasma on Edxis Chromebook. It took me about 1 hour to install Debian 13.4.0 KDE Plasma. The reason why I buy this Edxis Chromebook is because the laptop battery could last more than 15 hours of usage without looking for an electrical power outlet to charge the laptop battery. Very very good laptop for travelling around the world. After installing Debian 13.4.0 KDE Plasma, I still have 18 GB of available disk space on the 32 GB eMMC. The / mount point has a total capacity of 27 GB and 6.9 GB was used by the Debian installation. The reason why I chose Debian is because ChatGPT says Debian is the most stable Linux distro in the world (but don't have bleeding edge Linux kernel like rolling distros). The reason why I chose KDE Plasma is because this desktop environment resembles Windows 10/11 most closely other than Cinnamon. I had also installed Google Chrome and VLC media player. LibreOffice was installed by default. But now I have no audio. Task bar says "No output or input devices found". During Debian installation, under Detect network hardware stage, it says: "Some of your hardware needs non-free firmware files to operate. The firmware can be loaded from removable media, such as a USB stick or floppy. The missing firmware files are: intel/avs/hda-8086280a-tplg.bin If you have such media available now, insert it, and continue. Load missing firmware from removable media?" I chose "No" during Debian installation. Now I have no audio on my Edxis Chromebook LI9 with Debian 13.4.0 KDE Plasma. Where can I find non-free firmware file intel/avs/hda-8086280a-tplg.bin?? Please advise. I also want to watch YouTube videos on my Edxis Chromebook with Debian 13.4.0 KDE Plasma. Thank you very much.
