Public bug reported:
Speaker audio output does not work on a Dell XPS 13 DX13260 (Intel Core 5 320,
Wildcat Lake), while microphone input works correctly.
Hardware:
- Model: Dell XPS 13 DX13260, product SKU 0E53
- BIOS: 01.00.01 (05/19/2026)
- Codec: Cirrus Logic cs42l43 over SoundWire
(sdw:0:2:01fa:4243:01, devid 0x042a43, rev 0xa1, otp 0x03)
- Kernel: 7.0.0-1008-oem (also reproduced on 7.0.0-27-generic)
Symptom:
Attempting to play audio through the speaker device produces no sound.
dmesg shows the machine driver falling back to a default SoundWire
configuration because no dedicated driver entry exists for this
hardware ID:
sof-audio-pci-intel-ptl 0000:00:1f.3: No SoundWire machine driver
found for the ACPI-reported configuration:
link 2 mfg_id 0x01fa part_id 0x4243 version 0x3
sof-audio-pci-intel-ptl 0000:00:1f.3: Use SoundWire default machine
driver with function topologies
This appears to cause the cs42l43 PLL to be configured with an invalid
0Hz input clock, which then hits a shift-out-of-bounds fault:
UBSAN: shift-out-of-bounds in .../sound/soc/codecs/cs42l43.c:1511:7
cs42l43_enable_pll.cold+0x17/0x4d [snd_soc_cs42l43]
cs42l43_pll_ev+0x151/0x190 [snd_soc_cs42l43]
cs42l43-codec cs42l43-codec: No suitable PLL config: 0xffffffea, 0Hz
sof_sdw sof_sdw: ASoC: PRE_PMU: cs42l43 PLL event failed: -22
cs42l43-codec cs42l43-codec: Error spkr_clock_stop IRQ
cs42l43-codec cs42l43-codec: Error spkl_clock_stop IRQ
sof_sdw sof_sdw: ASoC: POST_PMU: cs42l43 AMP1 event failed: -110
sof_sdw sof_sdw: ASoC: POST_PMU: cs42l43 AMP2 event failed: -110
Microphone input via the same codec works correctly, indicating the
codec and firmware load fine — this looks like a missing machine-driver
quirk / SoundWire clock configuration for this specific Dell SSID
(0e53), rather than a general codec or firmware fault.
Steps to reproduce:
1. Fresh install of Ubuntu on Dell XPS 13 DX13260
2. Attempt to play any audio through built-in speakers
3. No sound is produced; dmesg shows the trace above
Expected result: Speaker audio works.
Actual result: Silent playback, PLL configuration crash in dmesg.
Already tried:
- Updating from generic 7.0.0-27 to linux-oem-7.0.0-1008 — same crash,
same file/line, no change.
- linux-firmware is up to date.
