Audio overdrive after update to 15.2

After updating to PP 15.2 on Win10 the sound of 4-channel audio in a MXF-Container (AVC-I, 4:2:2, 10 bit, Varicam) is totally overdriven in every clip. All clips worked fine before the update.

 

The audio is a PCM, 1150kb/s, 48kHz, 28 bit. Other audio-clips (in mono and stereo) work fine. The audios in other video editors work also fine. The waveforms of the clips are very high. Some clips look and sound good in the first seconds and then they seem to crush.

 

There is a BM DeckLink Studio 4K installed. Drivers are updated. Changing in Premiere BEARBEITEN - VOREINSTELLUNGEN - AUDIOGERÄTE - AUSGANGSZUORDNUNG - AUSGABE ZUORDNEN FÜR from "Blackmagic Playback" to "Adobe Desktop Audio" does not fix the problem.

 

What can we do?

 

Kind Regards

Werner

Hi Werner,

 

We're sorry about the poor experience. We're investigating a similar issue that has been addressed in one of our Beta builds. Would you mind installing the latest Beta build from the Creative Cloud Desktop app to check if it's working properly? You may refer to this link to know more about Creative Cloud Beta.

 

Thanks,
Sumeet

Hello Sumeet

thanks for your reply!


after installing the beta version the following happens:

- The waveform preview of the 4-channel files in the timeline shows the right waveform
- The playback is not correct: Sometimes it seems, that the playback jumps back a few frames or leaves out some frames
- the yello warning triangle in the down right corner syas "Audio- und Videouhr sind nicht synchron in "Adobe Player"".


If I go to the menu BEARBEITEN -> VOREINSTELLUNGEN -> AUDIOGERÄTE and
- change the GERÄTEKLASSE from MME to ASIO and
- change the GERÄT to BLACKMAGIC AUDIO and
- change the AUSGANGSZUORDNUNG / AUSGABE ZUORDNEN FÜR to BLACKMAGIC PLAYBACK
the audio channels seem to work correctly.

 

My former workarround was to downgrade to a previous version, when the 4-channel audio worked well.

 

Do you recommend to downgrade again or to work on with the beta version?
(Please note, that we are working on a productive system.)

 

Thanks.
Werner
