I just purchased the Samsung BD-C5500 and the first thing I did when I got it was watch my collection of mp4 files. They played all back perfectly, video and sound both flawless. The firmware version that came with this Blu-ray player was 1001.0
Then I updated the firmware to the new 1010.4 version, and now after this update, none of the mp4 files play back any sound. The video plays back, but there is no sound. I get a "Not Supported Audio Codec"
message every time I play the mp4 files. These are the same mp4 files that played back perfectly with sound before the firmware update. These mp4 files contain audio using the AAC codec.
I searched and have read about this issue on number different forums involving the C5500 Blu-ray player and the C6500 model as well. It looks like many owners are having this problem with no audio with mp4 files after the firmware update.
This problem seems to affect mp4 files that contain AAC 6 channels, as well as mp4 files with AAC 2 channels. At first I thought the problem was only with the 6 channel AAC, but after further testing, it does affect both.
I called Samsung support about this problem, and the rep who answered claimed that this was the first time he had ever heard about it. After reading the forums to see that this "no audio" problem was reported more than a month ago and by a number of people, I find this astounding.
If you're affected by this, please call Samsung support to elevate the importance of this issue. Their support number is 1-800-726-7864 (1-800-SAMSUNG).
Apparently, a number of firmware updates have been released for this Bluray player since the problem was reported, and none of them have fixed the broken AAC audio problem. If more of us call, maybe this will get their attention to finally fix this problem that their update caused in the first place.
