It appears that this card has additional output channels (for [4,5,6,7].1 sound) on microphone and/or line-in connector[s] with autodetect. So, as far as I understand, what happens is this: 0. Line-out is disabled by default (windoze driver enables it at init). 1. FreeBSD driver loads, attaches&inits the card, doesn't enable line-out. 2. You insert the headphones/speakers/etc connector into mic (or already have it inserted). The card's chipset detects that, so it tells the mux to direct output signal (shifted 20 ms in time?) to mic connector. > --Mat Timestamp: 0x424062B0 [SorAlx] http://cydem.org.ua/
