The Pin Complex 0x17 (bass/woofer speakers) is incorrectly reported as
unconnected in the BIOS (pin default 0x411111f0 = N/A). This causes the
kernel to configure speaker_outs=0, meaning only the tweeters (pin 0x14)
are used. The result is very low, tinny audio with no bass.

The existing quirk ALC287_FIXUP_YOGA9_14IAP7_BASS_SPK_PIN (already present
in patch_realtek.c for SSID 0x17aa3801) fixes the issue completely.
