But a VU meter as option is useless for using TV sound.....

That is what I use, and I like it. I don't want the screen off, or a clock on the screen.

It was announced....

Display & UI:

1. Per-Input Now Playing: Customize the Now Playing screen for each input source.

But a VU meter as option is useless for using TV sound.....

Maybe for music concerts on TV.....

It's customisable now and it wasn't before. Where did you read that "display off" or the "clock screen" would be available?

People asked for this but so far WiiM didn't promise it would come with this or any other specific firmware version. It may well come at any point in time,.of course, so there's hope for you and others.

Hi everyone,

My WiiM Amp Ultra suddenly stopped appearing in Roon, even though all my other WiiM devices still show up normally.

The Amp Ultra is reachable on the network and seems to be working otherwise. Spotify Connect works, Chromecast works, and I can ping the device with no issues. But Roon doesn’t see it anywhere — not under Roon Ready, AirPlay, or other network devices.

I’m currently on firmware 5.2.809633. When the firmware update first popped up I hit “Not Now” because I was busy with my kids. Later when I opened the app again the firmware screen briefly appeared and then disappeared. The device now reports that the firmware is up to date.

I’ve done quite a bit of troubleshooting already. I rebooted the device, toggled the Roon Ready setting off and back on, restarted my Roon Core, and even did a full factory reset of the Amp Ultra. None of that changed anything.

For reference, I’m running a UniFi network with a Dream Machine SE. The Amp Ultra is connected via Ethernet. Roon Core runs on a Mac and I use Pi-hole for DNS, although my other WiiM devices work fine with the same setup.

I also ran a couple of network checks. The device responds to ping, and the Chromecast port (8009) is open. But the RAAT port (9200) refuses the connection, which makes me think the RAAT service simply isn’t running on the device.

Right now I can stream from Roon using Chromecast as a workaround, but the Amp Ultra never appears as a Roon Ready endpoint.

Has anyone seen this happen before after a firmware update? I’m wondering if the RAAT service failed to start and whether a firmware reinstall might fix it.

Thanks for any ideas.

TL, DR:

My WiiM Amp Ultra no longer appears in Roon after updating to firmware 5.2.809633. Other WiiM devices work fine. Chromecast and Spotify work, but RAAT port 9200 is closed, so it looks like the Roon service isn’t running. Tried rebooting and factory reset — no luck.
