From: Jabong Koo <[email protected]> The internal speakers on the LG Gram 17ZD90R-EX79K remain silent, while headphone output works normally. The machine uses a Realtek ALC298 codec with PCI subsystem ID 1854:048b. Existing LG Gram subsystem IDs 1854:0488, 1854:0489 and 1854:048a use ALC298_FIXUP_SAMSUNG_AMP_V2_4_AMPS, but 1854:048b is missing from the quirk table. Add the matching quirk for subsystem ID 1854:048b. Tested successfully on Ubuntu HWE kernels 6.17.0-41-generic and 7.0.0-28-generic.
