I just got a replacement ECS mother board . The first had bad video . The new one is a ECS A55F2-M4 . Its been running for about a day and I noticed---no audio ! I just want onboard audio. I dont see anything wrong with drivers , says "device working properly" in the audio section . I tried d/l the driver right from ECS and installed that. I also checked the cable and speakers . No audio . Any ideas ?? another bad , new board ??
