I can emerge the newest alsa-driver package (1.0.9b), but when I upgrade alsa-lib to 1.0.9, three things happen. First, my 32 bit sound applications, like mplayer32, don't work with alsa anymore. Second, the center channel on all 5.1 sound goes out. Third, the a/v synchonization on mplayer gets hosed using alsa (oss emulation still ok.) ====================================================================== ---------------------------------------------------------------------- robert - 08-18-05 21:12 ---------------------------------------------------------------------- Those mplayer options do nothing to fix the problem. The bug is in NFORCE.conf. Somebody decided to break it for alsa-lib 1.0.9 for unknown reasons. Narrowing the problem down to this file took several hours. At least one other person (bug # 1206) has the same problem. I've also found the bug on an AthlonXP nforce2 board. My conclusion: It's likely that nobody with an nforce motherboard has functioning surround sound in Linux right now. How did this happen? Was there no TESTING before these changes were made? End users (who have no clue how to debug this kind of stuff) will never be able to straighten this out. ---------------------------------------------------------------------- rlrevell - 08-18-05 21:31 ---------------------------------------------------------------------- So are you volunteering to buy me an Nforce2 motherboard? Otherwise, please fuck off.
