Same here on Powermac MDD 2003 1,25 GHz and MDD 867MHz DP. I also recognized that sound came at the same time from both ports, front speaker and line out. I booted back to Leopard, took out the cable for line out and maxed the volume for the front speaker. after reboot to mos i think the sound was half of original mac sound in volume. before i could hear only whispering sound with max volume in mos2.6. perhaps it was just a feeling. ill make some more tests tomorrow. my sound at mac mini works fine. no problems at all!
