The internal speaker will be disabled if multi-streaming audio is enabled.

Refer to alc262 specification

Two stereo DACs support 16/20/24-bit PCM format for stereo audio playback
on the rear panel, plus 2 channels of independent stereo sound output
(multiple streaming) through the Front-Out-Left and Front-Out-Right
channels

Supports MONO line output with independent volume control

> - pulse audio, detects the internal speaker as master, so if if use the
volume control in gnome 3, line-out gets muted, and the internal speaker is
used

the auto parser of hda codec does not differentitate those internal chassis
mono speaker of the desktop (cfg->mono_out_pin) from those speaker of
laptop (cfg->speaker_outs)

this also cause some lenovo workstation with ad1988 codec fail as the
driver try to assign the fifth dac to the mono speaker instead of the
headphone.

a possible way is use node 0x02 for line out and mono speaker , node 0x03
for the headphone.

front playback volume use node 0x0c 's amp-out
headphone playback volume use node 0x0d 's amp-out
mono speaker volume use node 0x0e 's amp-out

the mono speaker playback switch cannot be the slave of virtual master.

the mono speaker should be muted when either line out or headphone is
plugged.
