Anyone else having massive lip sync issues when watching TV (using hdmi arc) after this latest firmware? Ticket raised because I can't watch TV like this, it's horrible!

I had it until I performed a new "Synch Audio".

I noticed lip sync issues with TV sound via optical input, so perhaps it is related.

Can we have everyone getting the update reporting it

I had the idea that there was some versions variations and it was to show the version I got. But maybe I had a wrong idea

Afaik sync audio is for syncing when using different speakers (in different room setups), not for TV? Because no matter how I change the manual sync, it doesn't change anything for the lip sync problem.

Ok. It did for me. Changed the timing with about +25ms. The sync via HDMI is fine now. Was really bad before.

The sync measures how long time the processing of the signal is before coming out of the speakers.

Maybe you can control the picture delay on the TV to match this?

Or if TV out is not set to PCM, try that.

Tv is always set to PCM here. I'll see if I can change anything on the TV...

Ok, having watched different shows/programs on different stations now, things seem back to normal. Very weird...

With or without running the "synch audio"?

Without.

After the v5.2.711448 - Mar 22, 2025 update I was having issues with the TV/HDMI mode. When I would change the audio input mode to ethernet or other source and then back to TV the audio would not work on the TV/HDMI input. After this update, v5.2.714249 - Apr 18, 2025, this is no longer an issue.

I can well do without "smarter HDMI ARC" if it results in lip sync issues, 75% of what I use my Ultra for is watching TV either streaming from Prime, Netflix, Disney + and Plex. For that it's the best thing I've purchased, I'll keep reading this post till Wiim have cleared up all the problems that preople seem to be getting then I will think about upgrading the firmware. Thanks to all you folks who are posting your concerns on this forum, much appreciated.

Recently updated to 5.2.714249 with build date 20250418. After playing music without issue from early am today, mid morning suddenly no sound output over coax to my DAC. Checked everything and the WiiM is ‘playing music’ but no sound from my speakers. Was short of time so tried reboot, remove power then wait and power back on. Again, looks lie music playing but no sound either streaming or via my has attached to usb. I’m guessing a factory reset?

I just had a similar issue. After switching the output from DLNA back to line out, no sound from my speakers. Fortunately, a reboot fixed my issue.

Yes. Unfortunately the persistent groups has never worked as expected. I don't use them any more.

Unfortunately, but I have decided to do so too...

If TV out is set to PCM, I see LPCM on the Ultra. many issues lately, sometimes lipsync, but mainly audio dropouts. Wiim support said it was better to use AC3, and used TV DD out for a long time without issue. might be the google streamer since I just heard an audio dropout streaming Netflix with TV set to PCM.

using PCM or DD output on your TV? Internal TV apps or streamer? Is the dialog fine? do you feel the need to adjust volume to hear dialog between loud passages?

There has been an issue with HDMI CEC Power Control right from the start. When enabled it works as expected but if disabled a connected TV still "see" the WiiM Ultra, even when the Ultra is in standby. So to avoid that the TV changes to external speakers every time it is turned on, I need to disconnect the HDMI cable unless I want to listen via the WiiM.

I surely hope this is what had been fixed now.

Hi hgo58,

I’m not sure I fully understand your requirement—could you please elaborate a bit more?

In general, if you prefer to use your TV’s internal speakers, you can select them directly in your TV’s audio settings. When you want to switch to the WiiM device, simply select external speakers as the output target.

The option you're referring to is designed for a special case:
If the TV is set to external speakers but the WiiM device is in a different input mode (not HDMI), the device won't automatically switch to HDMI unless this setting is enabled.

Let me know if you need any further clarification—I’m happy to help!
