OK, that's good to know. > control.43 { > comment.access 'read write' > comment.type BOOLEAN > comment.count 1 > iface MIXER > name 'Spread Front to Surround and Center/LFE' > value true > } So, you're playing two-channel samples and get no output from surround and CLFE? Or, does it happen if you play a real 5.1 channel file? (for example, try speaker-test -c6) Also, it'd be helpful if you compare /proc/asound/card0/codec97#0/ac97#0-0+regs file before and after the patch. This reveals which register bits differ actually. thanks, Takashi - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
