Yes I agree with that. From your earlier message, I couldn't tell if it was clear that the settings were chosen by the distro (several of them), not accidentally selected by end users rebuilding the kernel with custom options. I think we're on the same page now. > We'll try to make the options more self-explanatory, in the mean time, > can you please try and confirm the hypothesis that it's indeed a Kconfig > option issue 1) With SND_SOC_SOF_INTEL_TOPLEVEL=n and SND_SOC_INTEL_SST_TOPLEVEL=y on v5.3.7: The reported errors disappear, and sound works (just like others have said). 2) With SND_SOC_SOF_INTEL_TOPLEVEL=y and SND_SOC_INTEL_SST_TOPLEVEL=n on v5.3.7: The reported errors disappear, but sound does not work. I manually installed the appropriate SOF v1.3 firmware file¹, and it loads: sof-audio-acpi INT3438:00: Firmware info: version 1:1:0-5dd9a sof-audio-acpi INT3438:00: Firmware: ABI 3:7:0 Kernel ABI 3:8:0 sof-audio-acpi INT3438:00: firmware boot complete but ALSA only sees the HDMI interface. This is appearing several times in dmesg: broadwell-audio broadwell-audio: info: override FE DAI link Codec broadwell-audio broadwell-audio: ASoC: CPU DAI snd-soc-dummy-dai not registered 3) With SND_SOC_SOF_INTEL_TOPLEVEL=y and SND_SOC_INTEL_SST_TOPLEVEL=y on the current sound subsystem tree (with the DSP probe module for Intel platforms²): The behavior is no different than what was originally described in this bug. Perhaps (2) is a separate issue (potentially misconfiguration on my part), and/or (3) may not be completed yet, but I hope this is useful. ¹ https://github.com/thesofproject/sof/releases/download/v1.3/sof-bdw-gcc.ri ² https://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound.git/commit/?id=82d9d54a6c0ee8b12211fa4e59fd940a2da4e063 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1846539 Title: [broadwell-rt286, playback] Since Linux 5.2rc2 audio playback no longer works on Dell Venue 11 Pro 7140 To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1846539/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
