Headphones from J1 and Multichannel output - no signal from J1

Hi!

Taken from kX support:

"On most 10kX boards, the "front" channel analog output is generated by the AC97 codec whereas the rear channel is done by an I2S codec. For this reason (I2S output is generally superior to AC97 output), kX Audio Driver swaps the 'Front' and 'Rear' connections by default. Note that in the case of Audigy and Audigy2 boards, an I2S codec is used for front output, and the AC97 codec is used for recording from onboard analog connectors only. However, it is still recommended to swap the Front and Rear connections because the output signals from the AC97 codec (even muted) are still connected to the 'Front' output of the card (and this impacts sound quality).

The best way to understand all of this, and to take advantage of it, is to not see the 10k1 and 10k2-based cards as audio cards with front and rear outputs and all, but simply as a 4 stereo channel output chips (which they actually are). Nobody tells you that you MUST use the "green" connector for your front speakers; you can just as well use it for your headphone output, and use the "black" (rear) connector as the feed to an audio system (in a club, use the green connector for headphone, black for the house audio feed, and start DJ-ing with 2 separate audio channels). Why use the black for the house audio system? Simple - the black (rear) channel uses the I2S codec, and thus produces better sound... and the audience deserves the best :-)."

On Audigy 2 (SB0244) w/ original drivers, headphones connection from J1 disappears when speakers are set for multichannel output 4/4.1.

Where are these signals coming from into J1 headphone R/L out pins (from ch 3/4 on I2S ??) ?
