Takashi,
Do you know anything about NIDs 0x25 and 0x26 on the ALC883 chip? 0x25 is an Audio Output and 0x26 is an Audio Mixer. They appear completely separate from the 0x0c-0x0f mixers, but when I map one of my pins to use the 0x26 mixer, I hear audio over the jack whenever I play to the standard 'Green' 0x0c mixer. The 0x26 mixer seems unused in the current driver, so I'm not sure if there is something special about it. I'm basically trying to use it as a 5th output.
Also, when I play audio, the 0x0c mixer has a nice full sound (the "expected" sound). The 0x0d & 0x0e mixers have much less bass and sound like someone turned up the treble. The 0x0f and 0x26 mixers have an even more "tinny" sound. I've verified that all the mixers/pins are configured the same exact way and all have full volume (0x1f). Do you know of any reason why the audio output over the pins would differ? I'm not sure what I could be missing here to get them to all sound the same.
I appreciate any info you could provide. Thanks, -Andrew
This is my 0x26 / 0x25 config, mapped to pin 0x1a which I've reconfigured as an output jack:
