Audio Playback issues with external audio interface on a Mac
Hi all,
I’ve been using a Apogee Duet 2 as an audio interface to playback my audio from within Premiere Pro. I have no video interface set to output, so I just have this audio device outputting audio while I monitor video from my computer monitors. All was good until recently audio started playing back noisy and distorted with a weird digital scratchyness effect. I tested other apps such as Audition, and did not run into the issue at all. It seems isolated to Premiere Pro and Prelude.
When I switch to internal speaker, the audio coming from my computer sounds fine, but the moment I switch to the Apogee, it gets all garbled.I tried reinstalling the Duet 2 drivers as well as reinstalling Premiere Pro entirely!
I don’t know what happened, but I can no longer playback clean audio from my Duet 2 audio interface. For reference this sound is similar to when you select a seperate audio device from video, and trying to playback, which I guess is a issue in Adobe, which is why they ask us to always select the video and audio device to the same.
But in this particular situation I have no vide device, so shouldn’t my audio interface playback fine? If I’ve already done re-installs, what’s next?

What are your audio preferences set to inside of Premiere? Can you screen shot them?

I had the audio set to System Default. After trashing the preferences and selecting my audio device in Audio Hardware preferences, and then setting my audio playback to Adobe Desktop Audio, it seems to have fixed the issue.
So is it safe to say that I should always directly select an audio device and avoid the System Default setting?

Depending on the OS and audio interface yes. Adobe on Windows works fine with the WDM sound device and syncs perfectly. If the device supports Asio and the asio device is selected then the sync is often broken. OSX uses Core Audio and normally works fine with most devices. However Apogee may not like the OSX implementation of Core Audio and instead use their own since it’s an external device with different buffering. That really is device and bus dependent.
