[broadwell-rt286, playback] Since Linux 5.2rc2 audio playback no longer works on Dell Venue 11 Pro 7140

[RussianNeuroMancer]

[Impact]
With the current default kernel config, the SND_SOC_SOF_BROADWELL_SUPPORT
is set to Y, then it will make the legacy intel soc driver fail, and
moreover the current sof driver can't support broadwell well, as a
result, many broadwell computers with I2S codec can't support sound anymore.

[Fix]
Intel submitted a patch, it will make those two kconfig options exclusive,
and the legacy soc's option has higher priority, if both of them are
enabled, sof's option will be disabled.

[Test Case]
Build the kernel and check the debian/build/$buidling_dir/.config, the
SND_SOC_SOF_BROADWELL_SUPPORT is disabled.

[Regression Risk]
Low, so far, the sof driver can't support broadwell machine well, so
there is no machine use this driver yet.

Hello!

I noticed that since Linux 5.2rc2 audio playback no longer works on Dell Venue 11 Pro 7140 (Intel Core M-5Y71; rt286). Turns out that happened because SND_SOC_SOF_BROADWELL_SUPPORT was enabled in kernel binary builds since 5.2rc2: https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.2-rc2/

To verify this assumption I tested two builds of Linux 5.3.1.
1. Build with enabled SND_SOC_SOF_BROADWELL_SUPPORT from https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.3.1/

Audio playback doesn't work, dmesg:

Since kernel 5.2 there is no sound on my Broadwell-based laptop with bdw-rt5677 driver. The laptop is a Chromebook Pixel 2015 (Samus) converted to Linux with UEFI firmware by MrChromebox. There was no problem with this component with 4.19.*, 5.0.* and 5.1.* kernels up until 5.1.16.

I can confirm that this is an issue with Linux 5.2 and the bdw-rt5677 hardware. Downgrading to Linux 4.19.59 fixes the issue. This issue was not present in Linux 5.0 or 5.1. The hardware is a 2015 Chromebook Pixel (Samus).

Looking at Dmitry Savostyanov logs, we have very similar output. Our only difference is that I have not edited /etc/modprobe.d/modprob.conf to blacklist modules via udev. I will post additional information.

It's likely that you enabled both drivers for Broadwell, which is an invalid configuration. Just deselect SOF_BROADWELL with make menuconfig and retry.

[david.ward (david.ward-linux-kernel-bugs)]

Pierre,

1) This is occurring with the stock Linux kernel that ships with mainline Linux distributions (Fedora, Ubuntu, Arch Linux). It's affecting end users who just want sound to work out-of-the-box, like it did before SOF was introduced.

2) If selecting both kernel configuration options would produce an invalid build, that is a bug in the Kconfig files, which should be adjusted to enforce these dependencies.

Thanks!

The notion of stock kernel is misleading, it all depends on what options
are selected.

Indeed the distros don't seem to have a proper communication channel
with driver developers to make sure the options make sense. We just had
a case with Ubuntu where HDaudio support was removed due to the
selection of an option explicitly marked as 'use at your own risk'

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

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,

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.

[pierre-louis.bossart (pierre-louis.bossart-linux-kernel-bugs)]

Can you try to cherry-pick what's on

https://github.com/thesofproject/linux/pull/1382

that should prevent SOF from being selected if you've already selected
the legacy drivers.

[david.ward (david.ward-linux-kernel-bugs)]

With those commits cherry-picked on top of the current sound subsystem tree (aside from 65263bf16116 and 3f89e62cf14c, which both revert changes that are not in that tree), it works. The option for SOF support on Broadwell gets deselected automatically during the build, because the legacy driver is selected.

It's not easy to have multiple drivers for the same hardware. This bug is just an example what we are trying to resolve in distros. We need to compile _ALL_ drivers and let users to choose the right one. The best practise is to select the correct driver at run-time with the possibility that the user might force another one.

What we need to add the support the Chromebook Pixel 2015 to the universal distribution in this example. The SND_SOC_SOF_INTEL_TOPLEVEL=n is not a solution (DMIC for HDA DSP). Another option is SND_SOC_SOF_BROADWELL_SUPPORT=n . Ideally, we should have both SOF / SST drivers in the kernel and let users to select the right one (if the automatic selection does not work). If you confirm, that we can use the newer SOF driver for this hardware with the correct firmware files, it's also ok for us.

The code in commit f35bf70f61d389754fafd7fce75efbb3bd2eea87 (comment #11) assumes that SOF _or_ SST driver is built exclusively.

[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-eoan' to 'verification-done-eoan'. If the problem still exists, change the tag 'verification-needed-eoan' to 'verification-failed-eoan'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

[David Ward (dpward)]

There are two upstream commits that make the SOF and SST drivers mutually exclusive on a specific platform.

The one for Broadwell is now merged into the Ubuntu kernel:
https://git.launchpad.net/~ubuntu-kernel/ubuntu/+source/linux/+git/eoan/commit/?id=d46917958a6366f3c63501e9962b60dd7d33a3bd

But the matching one for Baytrail is missing. It should be merged as well:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit?id=df7257e544faf838c3e7ad6b4e89ffe59e87f5e1

Please file a different bug. The runtime conflict between SOF and SST drivers has been worked around for now, by making the Kconfig options mutually exclusive. This is still resolved even on Linux 5.5.1 (I'm testing on Arch Linux as well).

The issue you are seeing may be related to ALSA userspace or to PulseAudio instead of the kernel; both have been undergoing changes including the conversion to UCM2 profiles, which has unintentionally broken sound in some cases [1]. Please check journalctl for more output.
