DVD drive is detected with kernel 5.5.5 DVD drive is NOT detected with kernel 5.6 rc1 and 5.6 rc2 Drive is SATA Also tried Bluray drive - same result Tried this with the same hardware with different kernels on Mint 19. Additionally tried this with another different computer running Fedora 31 - same result with kernel 5.6 rc1 and 5.6 rc2 Something has definitely changed within the kernel which is no longer detecting optical drives. I'm aware the floppy is being retired but it's a little too soon for optical media - I still have a lot of older backups on DVD. Could you please restore the optical drive detection.
Still problematic with 5.6 rc3 Manjaro users are also reporting this: https://forum.manjaro.org/t/optical-drives-not-recognized-in-kernels-5-6rc2/126067 The system is able to see the drives: $ inxi -d Optical-1: /dev/sr0 vendor: HL-DT-ST model: BD-RE BH16NS40 dev-links: N/A Features: speed: 48 multisession: yes audio: yes dvd: yes rw: cd-r,cd-rw,dvd-r,dvd-ram Optical-2: /dev/sr1 vendor: TSSTcorp model: CDDVDW SH-S223C dev-links: N/A Features: speed: 52 multisession: yes audio: yes dvd: yes Reverting to kernel 5.5.5 fixes this.
On kernel 5.6rc3 I was able to play a DVD in VLC after opening the disc in MakeMKV. It is still not showing in the device notifier in Plasma, nor does K3b detect a disc in inserted. Here are my drives: Optical-1: /dev/sr0 vendor: PIONEER model: BD-RW BDR-209D dev-links: cdrom Features: speed: 125 multisession: yes audio: yes dvd: yes rw: cd-r,cd-rw,dvd-r Optical-2: /dev/sr1 vendor: ASUS model: DRW-24F1ST c dev-links: N/A Features: speed: 94 multisession: yes audio: yes dvd: yes rw: cd-r,cd-rw,dvd-r,dvd-ram
I can confirm that kernel 5.6 rc4 has resolved drive detection - I will try out a few disks to verify this is fully functional.
Kernel 5.6rc4 has resolved the issues I had with my optical drives as well. I have tried both video and audio discs.
Kernel 6.12.10: the BD-RE device isn't detected nor is a media present in it also detected. The device opens and closes but it doesn't spin the media when inserted and therefore it's not reading it. When an empty media is inserted, programs like k3b return "no media detected". The BluRay device is HL-DT-ST BD-RE LG BH16NS55. Note: I can't try kernel 6.13 (Arch Linux) because with all kernels of version 6.13 and above (the current kernel for Arch is 6.13.4) my hardware (Intel i7-12700F CPU + RTX 3060 GPU) are running way hotter than they should be when idling. Like 13-20 degrees hotter.
Since I can't edit my previous comment, I'll add a new one: I figured it out what the problem is - somewhere between kernels 6.1 and 6.12 (both rolling and LTS) something has been removed from them that helps the BluRay device recognize the "Linux only" filesystem on the bluray disc. I have burned a few TV shows with this filesystem ("Linux only", which is available in k3b) with the same device and these are the discs that the optical device now doesn't recognize and behaves as if there's no disc in it. All older TV shows which were burned with filesystem "Windows/Linux" (9660) are being recognized and read just fine.
