If someone confirms that this is the correct place for a bug report, I will delete it... Hello, I am running Ubuntu on an HP Elite x2 G8 Tablet (Intel Tiger Lake platform). The audio system uses a Realtek ALC3292 codec combined with two discrete NXP TFA9894 amplifiers for the internal speakers. Currently, the internal speakers are not working correctly (routing issue/wrong fixup applied): 1 - When testing the LEFT channel, sound comes out of BOTH internal speakers simultaneously. 2 - When testing the RIGHT channel, there is absolute silence from the internal speakers. 3 - Audio via the headphone jack (wired) and Bluetooth works perfectly in full stereo. It seems the driver applies a generic ALC285 fixup (SSID 103c:0000) and fails to properly initialize or route the right-channel NXP TFA9894 amplifier via ACPI/I2C. I have attached all the necessary debug logs, including alsa-info, codec dump, dmesg, and nhlt.bin. I can disable Secure Boot and test experimental kernels or SOF topologies.I'm ready to provide any logs, command outputs, or anything else needed to fix the sound on this device! Because the sound was simply amazing under Windows 11! And I really miss it.Could you please help with a proper kernel quirk/fixup for this specific hardware configuration? Thank you!
