DLNA audio sync - audio is ahead of video - mattb - 2024-11-30
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.

RE: DLNA audio sync - audio is ahead of video - TheDreadPirate - 2024-11-30
Does it transcode on your other clients? Or just the TV?
RE: DLNA audio sync - audio is ahead of video - mattb - 2024-11-30
Also worth mentioning. Jellyfin runs on an M2 SSD (Samsung 990 Pro 1TB mirrored), while the media is on a separate volume.

RE: DLNA audio sync - audio is ahead of video - TheDreadPirate - 2024-11-30
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.
RE: DLNA audio sync - audio is ahead of video - mattb - 2024-11-30
Is that located --> Profile / Playback / Video Quality / Maximum Allowed Video Transcoding Resolution / 720p?
I tried this and it still misaligned, previously this was Auto.
RE: DLNA audio sync - audio is ahead of video - TheDreadPirate - 2024-11-30
No. You have to change the DLNA profile your TV is using (the device profile name is in the log).
