I’m having a problem with AC3 as well, not rapid clicking, just no sound at all.
I thought it might be my receiver, which is fairly old (Yamaha DSP-A1), but playing from a standalone DVD player with AC3 (Dolby Digital) via optical is good.
My equipment is connected as follows for audio:
WD Live Hub > Optical > Yamaha DSP-A1 (no AC3)
Zenith DVB-318 > Optical > Yamaha DSP-A1 (AC3 good)
XBox 360 > Optical > Yamaha DSP-A1 (
All video is via discrete inputs from component to TV.
Initially, I was having a problem with mkv’s on the Hub, internal and external drive, where anything with AC3 at 640K would have pops, but that’s probably because of my receiver which may only support 448K AC3. After this recent firmware update, NO Dolby Digital is playing.
I have tried taking previously working mkv’s and converting the 640K AC3 to 448K AC3 and remuxing…no sound. Even ones that had 448K AC3 to start with are not playing with sound. Video is fine. DTS is fine. AAC is fine.
