There is no dv5 model as 92HD81 use

speaker-test -c4 -D hw:0,0 -t wav

92HD81 only support up to four channels

4 Channels (2 stereo DACs and 2 stereo ADCs) with 24-bit resolution
•Supports full-duplex stereo audio and simultaneous VoIP •Provides a mono


The two internal speaker nodes have the same sequence number zero in the
pin ficup

Trying remove PCI quirk and use auto to find out node 0x0f is the internal
