Infinix INBOOK Y1 PLUS speakers not working - ES8326 chip on Ice Lake

[Tuwel006]

Hi,

I have an Infinix INBOOK Y1 PLUS laptop and the internal speakers
do not work on Linux. Bluetooth and HDMI audio work fine, but the
built-in speakers are completely silent.

System details:

• Laptop: Infinix INBOOK Y1 PLUS
• Board: EM_IC325_200B_V1.0
• BIOS: ICL_IC325_LPDDR4X_200B_IN_V2.0.6
• CPU: Intel Core i3-1005G1 (Ice Lake)
• OS: Ubuntu 24.04.4 LTS
• Kernel: 6.17.0-14-generic
• Audio chip: ES8326 (ESSX8326) on Intel SOF Ice Lake-LP

The audio card is detected correctly and aplay -l shows it:

card 0: sofessx8336 [sof-essx8336], device 0: ES8336 (*) []

Audio signal is also reaching the hardware - I can see volume
spikes in the sound settings UI when playing audio, but nothing
comes out of the speakers.

From dmesg:

es8326 i2c-ESSX8326:00: assuming static mclk
sof-essx8336 sof-essx8336: quirk mask 0x0
sof-essx8336 sof-essx8336: quirk SSP0
Topology file: intel/sof-tplg/sof-icl-es8336-ssp0.tplg

GPIO info shows the speaker amp pin:

line 130: "speakers-enable" output active-low [used]

So GPIO 130 is detected and claimed by the driver, but it seems
like the DAPM path never actually triggers it to enable the
speaker amplifier.

The UCM profile from alsa-ucm-conf also fails to initialize:

unable to execute cset 'name='DAC Mono Mix Switch' off'
error: failed to initialize new use case: HiFi

I think the UCM profile is written for ES8336 but this laptop has
ES8326 which has different mixer control names.

I tried quirk values 0x00, 0x10 and 0x18 but none of them made
the speakers work. The ACPI path for the device is
_SB_.PCI0.I2C2.ESSX and the PCI ID is 8086:34c8.

I also saw a similar report for the Infinix INBOOK X2 here:
#3873

Could you please add a DMI entry for this laptop model with the
correct GPIO configuration for the ES8326 chip? I am happy to
test patches or provide any additional information that would help.

Thanks
