Bug 2531233

1. Please describe the problem:

Audio is completely unavailable on Fedora 44 Atomic (Sericea) on a Dell XPS 14 DA14260 after upgrading the kernel.

Hardware:

Intel Core Ultra Processors (Series 3) HD Audio
PCI ID: 8086:e428
Dell subsystem: 1028:0db9

Kernel driver in use:

sof-audio-pci-intel-ptl

With kernel 7.1.12-200.fc44.x86_64, ALSA registers the sof-soundwire card normally and exposes Jack Out, Speaker, and HDMI playback devices.

With kernel 7.2.4-200.fc44.x86_64:

cat /proc/asound/cards

returns:

--- no soundcards ---

and:

aplay -l

returns:

aplay: device_list:279: no soundcards found...

The most significant difference in the kernel logs is the probing of the four Cirrus Logic CS35L57 SoundWire amplifiers.

On the working 7.1.12 kernel, all four devices initialize successfully and report:

Cirrus Logic CS35L57 Rev B2 OTP1 fw:4.2.1 (patched=0)

The kernel then continues loading the SoundWire topology, applies amplifier calibration, and registers the sof-soundwire sound card.

On the broken 7.2.4 kernel, all four CS35L57 amplifier instances fail during probe with messages such as:

error -EBUSY: Failed to get spk-id-gpios
probe with driver cs35l56 failed with error -16

The kernel also reports:

No SoundWire machine driver found for the ACPI-reported configuration:
link 0 mfg_id 0x01fa part_id 0x4245 version 0x3
link 2 mfg_id 0x01fa part_id 0x3557 version 0x3
link 3 mfg_id 0x01fa part_id 0x3557 version 0x3

followed by:

Use SoundWire default machine driver with function topologies

However, the working 7.1.12 kernel also reports this SoundWire machine-driver fallback and successfully initializes the audio hardware, so this warning by itself does not appear to be the regression.

The apparent regression is that the CS35L57 amplifiers successfully probe on 7.1.12 but fail with "Failed to get spk-id-gpios" / error -16 on newer kernels, after which no ALSA sound card is registered.

2. What is the Version-Release number of the kernel:

Currently broken:

7.2.4-200.fc44.x86_64

Also confirmed broken previously:

7.1.13-200.fc44.x86_64

Last known working:

7.1.12-200.fc44.x86_64

3. Did it work previously in Fedora?:

Yes.

Audio works normally on:

7.1.12-200.fc44.x86_64

The issue first appeared for me after upgrading to:

7.1.13-200.fc44.x86_64

I no longer have the 7.1.13 deployment available for logs because I updated to 7.2.4 before realizing the regression would persist.

The issue remains present on 7.2.4-200.fc44.x86_64.

Booting the preserved 7.1.12 deployment still restores audio immediately with no other configuration changes.

4. Can you reproduce this issue? If so, please provide the steps to reproduce
   the issue below:

Yes, consistently.

1. Boot Fedora 44 with kernel 7.2.4-200.fc44.x86_64.
2. Run:

cat /proc/asound/cards

Result:

--- no soundcards ---

3. Run:

aplay -l

Result:

aplay: device_list:279: no soundcards found...

4. Reboot into the preserved 7.1.12-200.fc44.x86_64 deployment.

Audio works normally again, and sof-soundwire is registered without making any other configuration changes.

5. Does this problem occur with the latest Rawhide kernel?

Not tested. This is an rpm-ostree based Fedora Atomic system, and I did not rebase or otherwise convert the system to Rawhide for this test.

6. Are you running any modules that not shipped with directly Fedora's kernel?:

No third-party kernel modules are being used for the audio hardware.

The audio device is using Fedora's:

sof-audio-pci-intel-ptl

with kernel modules including:

snd_sof_pci_intel_ptl
snd_hda_intel

7. Please attach the kernel logs.

Attached


Reproducible: Always
