The HP Victus 15-fa2xxx (subsystem ID 103c:8dcd) uses two TAS2781
amplifiers connected via I2C bus at addresses 0x36 and 0x37.
Without this quirk, the amplifiers remain uninitialized causing
mono audio output with no bass.
Tested on HP Victus 15-fa2xxx (HP-VictusbyHPGamingLaptop15_fa2xxx--8DCD)
with kernel 6.19.0-9-generic on Ubuntu 26.04.

stable kernel tree. Please read:
