I've been having some annoying problems with my Realtek ALC850 (AC'97) on-board sound (I have a A8V Deluxe mobo (amd 64)), and I finally narrowed it down to the jack sensing technology (I think). Basically, this board tries to figure out how many speakers you have connected to the board, and decides which channels to send to each jack. Problem is, mine seems to be doing a lousy job at it: I get a monoaural signal to my speakers, loosing the right channel; if I connect my headphones to the same jack, I get stereo. I have a 2.1 set (Bose Companion 3), which only uses one jack (line out or spkrs). I get the same effect with my old 2.1 Yamaha speakers (bought a new set because I thought they had died ...sigh...). Speakers have been checked on a different machine, and work. My question is: Anyone with this hardware managed to make it work? How did you do it? What kernel version did you use? What module options? What do you have connected to it? I'm using SuSE 9.2 stock (up to date with the patches), 64 bit. I'd appreciate some help! TIA
