Audio Sync Issues on tvOS 18.1 with Infuse 8.0.3

After updating to tvOS 18.1 and Infuse 8.0.3, I’ve started experiencing audio sync issues. Here’s a breakdown of my setups:

Working Setup:
• tvOS: 17.6
• Infuse: 7.8
• Audio Sync: No issues, perfect sync.

Affected Setup:
• tvOS: 18.1
• Infuse: 8.0.3
• Audio Sync Issue: Audio is delayed by about 4-5 frames across multiple formats, including AAC 5.1, DTS 5.1, and AAC Stereo.

I’ve attached video clips below that demonstrate the sync problem. I know a temporary bandaid can be to manually adjust audio delay, but wanted to bring this issue to your attention.

I don’t know if its tvOS or Infuse causing the issue, I do not want to update me other TV to find out…

To add to this, these files are in perfect sync on tvOS 18.1 within the Plex client but still about 170ms delayed in Infuse playback. If it helps to submit a diagnostic I can do so. Thanks in advance.

What type of device is this Apple TV connected to (EG AV receiver, TV, soundbar, etc…)?

Do you have the Match Content options enabled on the Apple TV?

Can you try resetting the Apple TV’s Video Settings (found in Apple TV Settings > Video & Audio) and the re-enabling the Match Content options to see if this makes a difference?

Hi James,

This particular TV is just outputting audio through its built in speakers.

Typically I do not have Match Content options enabled because I use SDR only settings and SDR content for all of my personal media.

However, I followed your suggestions to reset video settings and re-enabled Match Content options to test the files. I am seeing a very slight improvement, by approximately one frame.

I noticed the same today. The audio was slightly out of sync.

Good to see that fixed it for you.

Still experiencing some delay on my set up, so I am curious, has anyone on the dev team experienced/been able to recreate the issue even with match content turned on?

Cheers

I haven’t been able to use Infuse for at least 3 weeks now due to the audio streams being out of sync. The suggested settings reset made no difference. I had to switch back to using Plex for now.
