Hi everyone,
I’m looking for help regarding an audio issue on my Positivo Vision C14 laptop (Intel Alder Lake-N N100 processor). The system detects the sound card, but there is no audio output from the internal speakers or the 3.5mm jack (Dummy Output or total silence).
Technical Specs:
-
Codec: Everest ES8336 (ESSX8336)
-
Driver: Sound Open Firmware (SOF) -
snd_soc_sof_8336 -
OS: Zorin OS 18 (based on Ubuntu 24.04 LTS)
-
Kernel: (Type
uname -rin your terminal and paste the result here, e.g., 6.8.0-40-generic)
What I’ve tried so far:
-
Resetting ALSA and AlsaMixer (
alsactl init). -
Installing SOF firmware and topology files (
.tplgand.rifiles) from various community repositories. -
Testing several quirks in
/etc/modprobe.d/alsa-base.conf(0x01, 0x02, 0x04, 0x41, 0x45). -
Manually unmuting all channels in
alsamixer(DAC, Headphone Mixer, Speaker, etc.).
aplay -l correctly lists the device as sof-essx8336, and the UI shows the volume bar moving, but no physical sound is produced. It seems to be a pin-mapping issue specific to this new Positivo model.
Has anyone managed to get the ES8336 working on this specific hardware or found the correct “quirk” code for the Alder Lake-N platform?
Any help would be greatly appreciated!
