Most of the configurations are stored in the WiiM device, so you will not lose those. You may lose the app only data, like the search history.
WiiM Ultra Firmware v5.2.715362 - Apr 29, 2025
- Thread starter WiiM Team
- Start date
Thx. it works, but now for a change I don't have volume control in the background
In the playstore there is only the previous version of wiim home 3.2.0 
Oh well, it will probably update to 3.2.1 at night
As said elsewhere, it looks like they’re reverted to the previous version until they fix the bug which might take a few daysThx. it works, but now for a change I don't have volume control in the background

I didn't notice
Regarding device auto-updates:
Happy to report that my WH app (device = Ultra, fw 5.2.714249) displayed a message advising that a device update was available, and offering the option to upgrade or not. Also, on reviewing the device screen the Firmware Version line has a blue up-arrow next to it, presumably offering the upgrade if selected.
I will wait another couple of days to confirm that no upgrade is forced.
The latest Wiim Home app update is not yet in Playstore, but it is not unusual to wait a few days for this.

Observations on Dolby and the new FW upgrade to simulate surround sound:
TV Output set at:
Stereo uncompressed PCM - LPCM 1536 16-bit/48 kHz (works but still has latency issues)
Dolby Digital (lossy compressed format) - AC3 1536 kbps 16-bit/48 kHz (no sync issue)
Dolby Digital Plus - as expected not supported
DTS - as expected not supported
It appears that the "upgrade" to Dolby Digital has changed the latency timing of the signal processing, hence the sync issues, due to the more complex encoding and decoding of the digital signal that DD requires. DD compresses and digitally processes the audio signal and can change the dynamic range and other auditory attributes of the output according to Dolby's algorithms for what Dolby thinks is optimal. PCM on the other hand represents the digital signal from the original source without additional processing.
Since I listen to music and concert videos more than movies on my TV, I prefer the sound offered by the PCM as then converted to analog with a good DAC like in the WiiM rather than the digital signal processing of the Dolby algorithm. I purchased the WiiM and got rid of my AVR for exactly this reason. This "upgrade" to faux surround sound is not an improvement in my opinion. Since the WiiM can still output the PCM stream all it would take is to be able to change the latency for PCM to the latency used prior to the Dolby upgrade when the WiiM encounters a PCM stream.

Hi Incognito,
Please kindly send us a feedback ticket so we can troubleshoot this for you promptly. Thank you for your support and patience!
So is this yet another FW update that doesn’t work properly?

Done, Thx!
If you’re having an issue with it too, then you should also submit a ticket so WiiM can inspect your logs
Does it help to open a ticket? I've had one open since April 30th and no response, not even an acknowledgment....

Not exactly. There was an update on March 6th that introduced Dolby 5.1. I believe this was when the audio sync with TV video was introduced due to, I believe, different latencies between Dolby Digital (DD) and PCM . In my case the problem with sync could be corrected by changing the TV output to Dolby Digital. Then an update on April 18th another FW was made available that included Smarter HDMI ARC that had issues primarily with how CEC was implemented and used by different individuals, but this update did not change the sync issue with PCM chosen as the TV output. (See the 18 pages of comment on https://forum.wiimhome.com/threads/wiim-ultra-firmware-v5-2-714249-apr-18-2025.6936/.) Due to issues with the CEC the update reverted to the prior HDMI behavior but most other FW updates from the March 6th and April 18 did not change.
The good - WiiM is continually trying to improve the functionality of WiiM devices
The bad - WiiM is continually trying to improve the functionality of WiiM devices
Of course - it not only notifies WiiM that there’s an issue but also submits your device logs for them to help diagnose the issue.
When you raise a ticket via the more/feedback section of the app, you automatically get a confirmation receipt email with the ticket number and text of the form:
“We would like to acknowledge that we have received your request and a ticket has been created.
Please note: While our team reads all the submissions, due to the volume of tickets, we will only reply to tickets that require additional assistance to resolve the issue. For feedback or submissions about known issues, we will take note and resolve it in an update. If you would like a reply from us, please reply to this ticket to let us know.”
WiiM will take note of it if it’s a known issue but won’t necessarily respond (although they often do) to that effect. They may also get back in touch if they need more information from you. And as they say in the text, if you would like a reply, you should respond to their acknowledgment email.
Not hearing for a few days after the acknowledgment is not unusual.
No, I'm just waiting for a Firmware that doesn't create more problems than it solves. I'm still running FW and the Home App from 2 months ago, it works absolutely fine for me. I can wait till Wiim get it right.....
