Hi! I got a HP dc7800 and my updated Fedora 8/ALSA 1.0.15 installation found all hardware and sound is playing. But if I connect my headphones to the rear plug there is nearly no bass. Even trying to use equalizers within programs doesn't help much. I tried to connect the headphone to the front outlet and there I get a reasonable signal. Now this PC has a builtin Speaker (which i disabled in the BIOS) and my guess was that there is a high pass filter and the speaker shares the same output as the rear jack. Does the AD1884 has a switchable high pass filter? Is there any chance to support that within ALSA to turn it off?
