Hi, recently I received a HP Pavilion DV6 laptop. Installed openSUSE Tumbleweed 20240801 on the machine. I can play an audio CD with VLC. If machine is suspended and then unsuspended, then attempt to play the audio cd again with VLC, audio playback FAILS and produces error messages, > "VLC is unable to open the MRL 'cdda:///dev/sr0'". Check the log for details. vlc-log dvdread error: Could not open /dev/cdrom dvdread error: DVDRead cannot open source: /dev/cdrom dvdhav error: Can'tstat /dev/sr0 dvdhav error: vm: failed to open/read the DVD repeats..................................... - Before suspending > inxi -Dd Drives: Local Storage: total: 111.79 GiB used: 18.23 GiB (16.3%) ID-1: /dev/sda vendor: Crucial model: CT120M500SSD1 size: 111.79 GiB Optical-1: /dev/sr0 vendor: hp model: DVDRAM GT80N dev-links: cdrom Features: speed: 24 multisession: yes audio: yes dvd: yes rw: cd-r,cd-rw,dvd-r,dvd-ram :~> lsscsi -v [0:0:0:0] disk ATA Crucial_CT120M50 MU05 /dev/sda dir: /sys/bus/scsi/devices/0:0:0:0 [/sys/devices/pci0000:00/0000:00:11.0/ata1/host0/target0:0:0/0:0:0:0] [1:0:0:0] cd/dvd hp DVDRAM GT80N R102 /dev/sr0 dir: /sys/bus/scsi/devices/1:0:0:0 [/sys/devices/pci0000:00/0000:00:11.0/ata2/host1/target1:0:0/1:0:0:0] list_ndevices: scandir: /sys/class/nvme/: No such file or directory NVMe module may not be loaded - After suspending > inxi -Dd Drives: Local Storage: total: 111.79 GiB used: 18.25 GiB (16.3%) ID-1: /dev/sda vendor: Crucial model: CT120M500SSD1 size: 111.79 GiB Message: No optical or floppy data found. :~> lsscsi -v [0:0:0:0] disk ATA Crucial_CT120M50 MU05 /dev/sda dir: /sys/bus/scsi/devices/0:0:0:0 [/sys/devices/pci0000:00/0000:00:11.0/ata1/host0/target0:0:0/0:0:0:0] list_ndevices: scandir: /sys/class/nvme/: No such file or directory NVMe module may not be loaded - dmesg output after suspending: :~> sudo dmesg | tail -30 [ 231.853253] [ T2862] [drm] ib test on ring 7 succeeded [ 233.259080] [ T2810] OOM killer enabled.
