Thinking it was something to do with my DVi-HDMI adapter cable I went out and purchased a Display Port-HDMI adapter cable, but it's the exact same thing - no hdmi recognised with newer kernel.
On LMDE, with two kernels installed. If i boot up with the kernel 4.15.0-041500-generic everything is fine - no issues with either the DVI/HDMI or Display Port/HDMI adapter cable being recognised aplay -l **** List of PLAYBACK Hardware Devices **** card 0: Intel [HDA Intel], device 0: 92HD81B1X5 Analog [92HD81B1X5 Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: Intel [HDA Intel], device 3: HDMI 0 [HDMI 0] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: Intel [HDA Intel], device 7: HDMI 1 [HDMI 1] Subdevices: 1/1 Subdevice #0: subdevice #0 On the very same computer, boot up with any newer kernel, for example my second kernel is 5.10.0.0.bpo.4-amd64 the kernel does not pick up the adapter. All i get is: aplay -l **** List of PLAYBACK Hardware Devices **** card 0: Intel [HDA Intel], device 0: 92HD81B1X5 Analog [92HD81B1X5 Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 Absolutely nothing else has changed - only the kernel. If i could build the current kernel but add in the sound module of 4.15.0-041500-generic i would, but there are no instructions on how to do that :-( Or can anyone point me to how it could be done? I don't mind building the kernel from source etc Thanks -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1834771 Title: No HDMI-audio after kernel 4.15.-0.50 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1834771/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
