DLNA audio sync - audio is ahead of video

[mattb]

Hi, I'm Matt and I'm running a synology ds1821+, previously running synology's video station.

I moved over to Jellyfin about 4-6 months ago, which I'm running in a container. Running latest Jellyfin 10.10.3 and DLNA 5.0.0

I'm having an issue where the audio is ahead of the actual movie, but only when streaming via DLNA to a Samsung TV.  If I run on laptop or phone, I see no delay.

This is happening across every movie/tv show I've attempted to stream to a TV.

Looking for guidance on how to get this resolved, this didn't happen when I initially moved over to Jellyfin.

Does it transcode on your other clients? Or just the TV?

[mattb]

Also worth mentioning.  Jellyfin runs on an M2 SSD (Samsung 990 Pro 1TB mirrored), while the media is on a separate volume.

[TheDreadPirate]

I'm thinking that the TV isn't capable of decoding the video fast enough, resulting in desync. You can try adjusting the DLNA profile to send 720P video instead of 1080P video.

[mattb]

Is that located --> Profile / Playback / Video Quality / Maximum Allowed Video Transcoding Resolution / 720p?

I tried this and it still misaligned, previously this was Auto.

[TheDreadPirate]

No. You have to change the DLNA profile your TV is using (the device profile name is in the log).
