Internal audio is weak and of very poor quality (crackling sound)

sdavoult · 2024-02-13 10:17:55

The sound from the internal speakers of my HP Dragonfly G4 PC is of poor quality (crackling) and very weak. It works perfectly under Windows, but impossible to get the sound to work properly under any GNU/Linux distribution.
I've been trying lots of things for several months (ACPI tuning, BIOS Update, Windows drivers recovery for use under Linux, Linux update > 6.7....) without success.
I feel like I've been poking around all over the Internet, but still no amplified sound.
Do you have any ideas?
Thank you very much!

I am sorry that no one has offered any answers for you. I am considering this model for dual booting Arch and Windows 11. Do you have the same problem with headphones?

It seems to be an issue with CS35L41.
Other models can be fixed with a kernel patch like this one: https://github.com/parmjotsinghrobot/hp … xx-snd-fix
I have tried modifying that patch to include a reference to our laptop, adding line:

+	SND_PCI_QUIRK(0x103c, 0x8b63, "HP Elite Dragonfly 13.5 inch G4", ALC287_FIXUP_CS35L41_I2C_2),

but it did not help at least for kernel 6.8. I have not tried 6.9 but it does not work out of the box either.

The machine code is correct and comes from

cat /sys/class/sound/hwC0D0/subsystem_id
0x103c8b63

Not sure what is wrong.

I'm just getting a Dragonfly G4 last week and trying to figure out the solution. It seems at least with 6.10 the sound/pci/hda/patch_realtek.c has been updated for this device:

	SND_PCI_QUIRK(0x103c, 0x8b63, "HP Elite Dragonfly 13.5 inch G4", ALC245_FIXUP_CS35L41_SPI_4_HP_GPIO_LED),

I believe at this point everything including ALC245 and CS35L41 are correctly "driven" by corresponding drivers, but in lack of calibration & configuration specific to this model at this moment. As stated in this message:

The CS35L41 HDA driver requires various system defined properties to configure the driver for an individual system. For some laptops, these properties are missing in the BIOS.

Since the CS35L41 is driven but not calibrated, from my experience a very rudimentary workaround is that, as long as it's operated at <40% volume, everything works correctly as long as there's nothing too loud and triggers

cs35l41-hda spi1-CSC3551:00-cs35l41-hda.1: Amp short error

I'm looking into whether a patch adding an entry to sound/pci/hda/cs35l41_hda_property.c would permanently fix the issue.

Update #1

Upon some digging, the driver loads the default gain=17 for all 4 speakers. The following symlinks will mitigate the issue and raise the 40% bar to approx. 80% but still easily triggering the error at 100%.

sudo ln -svf /usr/lib/firmware/cirrus/cs35l41/bincfgs/cs35l41-dsp1-14_5dB.bincfg.zst /usr/lib/firmware/cirrus/cs35l41-dsp1-spk-prot-103c8b63-{r0,r1,l0,l1}.bincfg.zst

Therefore, I created myself a cs35l41-dsp1-0dB.bincfg which tune down the gain from 17 to 0 which provides totally acceptable max volume and not triggering the error. However the value still seems to be adjusted in some conditions and still causes the error when actual output is loud enough.

Internal audio is weak and of very poor quality (crackling sound)
