[PATCH] ALSA: hda/realtek: Add HDA_CODEC_QUIRK for Samsung 750XBE/730XBE

From: Zhang Heng

Date: Mon Jul 20 2026 - 09:18:04 EST


Add a codec SSID quirk for Samsung ELECTRONICS 750XBE/730XBE using
HDA_CODEC_QUIRK() instead of SND_PCI_QUIRK(), because the alsa-info
report from this device does not expose a PCI subsystem ID, only the
HDA codec subsystem ID (0x144d:0xc824) is available.

This applies ALC298_FIXUP_SAMSUNG_HEADPHONE_VERY_QUIET to fix sound
being very low and distorted on the headphone jack of this system.
