Description Konrad 2007-05-28 21:10:03 UTC

For a few months I was unable to use my laptop with external headphones.

Today I tried ALSA under Knoppix, and saw interesting switch in alsamixer
named front duplication or something, which made my headphones output sound.

Then I downloaded ALC655 spec and found, that by default surround out is
enabled in bit 0 of 0x6a reg, so the signal only does to front speakers,
and headphones apparently aren't front speakers. :) In the sheet it's called:
S-OUT is duplicated output of LINE-OUT.

How-To-Repeat: Install FreeBSD on Amilo Pro V2055, start xmms and connect headphones, or
start mplayer in full screen (after patching the OpenChrome driver like I
did), and connect your laptop to a sound system, and try to hear something. :)

Please post the output of pciconf -lv | grep pcm . While this seems
to solve your specific model problem, it could introduce a regression
for other people with different type of hardwares but simmilar codec.


Thanks.

    and confusing for us idiot ***** users :P ........

Well, I think there should be no regressions, unless somebody is using 4-channel sound, because we only enable additional output of channels 1 and 2, disabling channels 3 and 4.
