Status for sound on Dell Chromebook 3120. On Ubuntu 22.04.2 (kernel 5.15.0-69-generic):
1. alsa-ucm-conf now seems to include the required UCM2 files. Hurrah! 2. you also need the firmware-sof-signed package, which you have to enable the "restricted" apt repository to get. Some people enable "restricted" already, when they install Ubuntu. 3. after a few minutes continuous playback the sound breaks (continuous beep). This is fixed by adding the module/boot option snd_sof.sof_debug=1, as described here: https://github.com/thesofproject/sof/issues/5437 Secondly, this system is affected by the same "after setting snd_intel_dspcfg.dsp_driver=2 the Sound is Pitched down and too slow". NOTICE: Upstream has suggested that future kernels will effectively default to "snd_intel_dspcfg.dsp_driver=2" on this hardware. I.e. the default would change from SOF to SST. If you have this "pitched down" problem, my only solution is to change back using the boot/module option "snd_intel_dspcfg.dsp_driver=3" ** Bug watch added: github.com/thesofproject/sof/issues #5437 https://github.com/thesofproject/sof/issues/5437 ** Bug watch added: github.com/thesofproject/sof/issues #3868 https://github.com/thesofproject/sof/issues/3868 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to the bug report. https://bugs.launchpad.net/bugs/1871306 Title: [SRU] No sound from internal card chtmax98090 (missing UCM2 files in alsa-ucm-conf) To manage notifications about this bug go to: https://bugs.launchpad.net/oem-priority/+bug/1871306/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
