809b now outputs audio in LCPM format instead of AC3

809B seems to output video which is set to profile H.264/ac3 with audio LCPM format and video only hence no audio. Reloading 808a works correctly and outputs audio as AC3. 809 seemed to break AC3 link when using My h264/ac3 profile or is not reading profile file properly. 808a work normally. 809b seems to have broken this profile use.

My test results are different, but equally puzzling. 809b.
1. Passing AC3 (Automatic) works.
2. Recoding AC3 (to different bitrate) results in no audio track.
3. Transcoding AAC to AC3 results in no audio track.
4. Transcoding AC3 to AAC works.
AC3 encoder seems asleep.

Have repeated Musicvid's test and concur with his findings. definitely something wrong with AC3 in 809b which was not there in 808a. Output always results in Audio of LCPM with video only which has no audion channel. 808a works correctly.

When the default Output profile is set toMP4 H264 video with AC3 audio then even QSF results in a video file with no audio track and sometimes H264 video with LCPM audio track with a setting of video only, hence no audio track.only. Unfortunately, some of my players require AC3 to work properly. Many older players do not support AAC.

We broke the AC3 encoder in 809b. 810 will be posted by tomorrow with the fix.
