It may do for him but it might not for you. There is NO universally good setting! Changing control 63 from Mic2 to Right PGA is just reducing the gain a little, which for some people prevents clipping round the mono mixer when control 12 is set too high. The better answer is to set control 12 correctly in the first place. _______________________________________________ Openmoko community mailing list [email protected] http://lists.openmoko.org/mailman/listinfo/community
