Correction/update: I discovered that my 5.1 front L/R speakers had been connected to the gray jack, but according to the motherboard manual gray is side speaker out for 7.1/8-channel. For 5.1 the front L/R speakers must be connected to the green/lime jack.
After moving front L/R to green, ALSA jack detection reports: Line Out Front Jack: on Line Out Surround Jack: on Line Out CLFE Jack: on Line Out Side Jack: off Direct ALSA surround51 playback now produces sound from all speakers in the correct order. The original PipeWire/WirePlumber issue may still need retesting separately with the corrected cabling. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2150545 Title: Possibly snd_hda_intel / Realtek ALC1150 jack detection issue: analog jacks report unavailable although ALSA surround51 playback works To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2150545/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
