Using ICH5/AD1985 (Intel P865PERL motherboard). Anomolies found: double-rate slot (DRSLOT) is set to 7,8 instead of the default 10,11 (register 0x20=0400 instead of 0). After setting 0x20 to 0, the rear channel jack starts working. RL/RR and Center/LFE are still swapped. I would assume the swappage was hardware, but the Center and LFE volume controls affect the speakers on the Center/LFE jack which would indicate the driver is incorrectly routing the signals. ====================================================================== ---------------------------------------------------------------------- tiwai - 10-25-05 17:56 ---------------------------------------------------------------------- Setting DR slot to 7/8 is intentional, as found in ac97_codec.c. The question is whether this still has influence even DRA bit is off on extended status regsiter. Could you check whether reg 0x2a bit 1 (0x0002) is off during playback of 48khz (or less) samples?
