P: No sound/audio when playing mts video

OK, here is another piece of data. Lightroom will load audio for one file each time it opens.

Lightroom does not close cleanly. When I exit the program, it leaves a running instance of lightroom in the task manager process list and leaves
dynamiclinkmanager.exe
dynamiclinkmediaserver.exe
Adobe QT32 Server.exe.
also running.

If I stop all those processes, I can open lightroom again and load audio for one file. The previously loaded files will still play, so it is like it is conforming the audio but gets stuck after the first file is completed.

I am having the same problem on a new install of Lightroom 4 with Production Premium CS6 on Windows 7 64 bit. Audio plays everywhere but Lightroom. Interestingly, after I installed Quicktime, I was able to get one video to play with the audio in Lightroom (an mp4 file), and it showed a brief "Audio Loading" message with a % notice before the audio was available. That file continued to play with audio when I returned to it in the catalog. But no other video file would play with audio and I never saw the "Audio Loading" message appear again. It does make Lightroom much less effective since I do many interviews and trimming would be very welcome based on the audio in the files.

I know the same issue occurs in Premiere until the audio has been conformed in the system. Does Lightroom 4 also conform the audio like Premiere? Is that what the audio loading message meant?

LR4.1rc2 doesn't play sound with HD video from Sony camcorder (*.m2t files)!

Stephen- I completely agree. Lightroom needs to do a better job of warning users when audio codecs are not supported. The bug has been filed internally.

I hope "working as expected" isn't the final answer. There should at least be some sort of warning on the screen to indicate that Dolby 5.1 isn't supported.

Hi Lily-

I replied to you in an email. Hopefully we can figure out what the issue is.

Hi Paul,

I get sound on all other video formats I've imported, including those from my canon dslr and point and shoot. This only seems to be a problem with the MTS format from my sony camcorder. Let me know if you have any other suggestions.

Thank you!
Lily

Lightroom supports playing Dolby Digital.

Do any videos play with sound in Lightroom?

Lightroom only uses the "default" audio device for audio playback. Make sure there are speakers (or a headset) attached to the default playback device. On Windows, you can right click on the speaker icon in the toolbar to see a list of audio devices and which is the default. You can also change the default here.

You can also open the volume mixer to see if sound is being outputted from LR.

I'm sorry - I misread your message and assumed you were on Photoshop CS5 or CS6 beta.

Lightroom 4 has different licensing from Photoshop.

I'm find a relevant and correct answer for you. :)
Thanks for your patience,
Meredith
