Corrupted embedded audio in the input – checksum errors
Audio sampling rate mismatch
The channel is configured for Dolby Passthrough, and the data present in
the selected Group/Channel is not Dolby AC-3
If Dolby Passthrough is configured, one additional indicator is shown:
•
Encoder 1/2 Passthrough: This indicator contains the status of the Dolby AC-3
Passthrough function. It may contain the following values:
o
Dolby AC-3, xxx kb/s: this means that the data in the selected group/pair has
been correctly identified as Dolby AC-3; its bit rate is reported here.
o
Unknown Format: this means that data is present in the selected group/pair, but
it is not Dolby AC-3.
o
Not Present: this means that there is no data in the selected group/pair.
If Secondary Audio is Enabled, then the status of both audio channels will show in the
Encoder 1 Status tab. The actual indicators displayed will depend on the individual settings of
each audio channel. The picture below shows an example where both audio channels are
embedded Dolby AC-3 Passthrough.
