[PATCH] ALSA: hda/realtek: Fix square wave output on ASUS Strix G615LR

[Zhang Heng]

ASUS ROG Strix G16 G615LR (PCI SSID 1043:3f20) outputs a loud
full-scale square wave from internal speakers since the TAS2781
amplifier driver started loading. The quirk was using
ALC287_FIXUP_TXNW2781_I2C which chains to the ThinkPad headset
jack fixup, but this is an ASUS device that should use
ALC287_FIXUP_TXNW2781_I2C_ASUS which chains to ALC294_FIXUP_ASUS_SPK
for proper EAPD and pin configuration.

Baojun, Antheas: several other ASUS Strix Gxx5 entries (0x3ee0, 0x3ef0,
0x3f00, 0x3f10, 0x3f30) are still using ALC287_FIXUP_TXNW2781_I2C (the
non-ASUS variant that chains to the ThinkPad fixup). Could you check
whether they also need to be changed to ALC287_FIXUP_TXNW2781_I2C_ASUS?
Ideally with testing on the affected hardware if possible.

Applied now.  Thanks.

The current quirk is well received for the ally. Perhaps switching to
ASUS would be simpler but I do not think the device is currently
problematic. I will defer to Baojun
