i own an HP Z400 Workstation, and audio is not working as expected.

The Problem:

• if i mute the internal speaker, the sound for line out is also muted

http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?objectID=c0171...

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.

• to hear something on line-out i use alsamixer, and control the volume

of the "speaker" output to 0

• but even if i set the output of speaker to 0, i can hear the music very

very silent..

• and last .. the control of "line" does nothing, mute/volume does not

affect the output

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.

Here some hardware info, if you need more, please tell me.
