Well, maybe it was just a bad connection, or my cable dying… One thing worth noting: even when there is crackling audio or no sound, the Amp still wakes up and goes to standby through HDMI CEC. I moved the elements closer and tried with a 2 meter cable, and it did not have the issue. Then I...

Hello, I recently bought this cable to connect my WiiM Amp to my Panasonic TV: https://www.audiophonics.fr/en/21-hdmi-hdmi-cable/hdmi-21-optical-cable-8k-60hz-48gbps-uhd-hdr-10-dhcp-22-edid-cec-earc-3d-5m-p-17974.html Unfortunately, it does not work: the Amp is not turned on by CEC, and the TV...

2 additional pieces of info: - it seems to only happen after a hard reset (AC plug pulled for 5 to 10 seconds) OR a firmware update - with this week's firmware update (5.0.614850), I had absolutely no sound over HDMI instead of the "usual" crackling audio, and I had to do a hard reset to recover...

unfortunately, I don't have another long enough cable, or a closer arc capable device to try but I think the issue starter to appear well over a month after I started using the device, and I haven't touched the cable also, I didn't have the issue on the humming PCB rev 2 that I had before, in...

Hi, I have a strange issue when waking up the device to play audio from the HDMI ARC source, and I'm wondering if anyone has experienced the same. It can be heard on https://drive.google.com/file/d/1Al72izVL_pHlQwE-YJ16T5PSGW3kwL1Y/view, there's some kind of crackling noise over the TV audio...

Yes, I'm running it. But I don't think I've ever seen a Wiim Amp firmware upgrade that also upgrades u-boot

As I said, the markings on the bottom of the unit are not the same as on my previous v4 unit. so it's definitely newer hardware

FYI, I finally got a replacement unit from french retailer sonvideo/easylounge, one month after returning my humming v4: - it's PCB_version 5 :) - and the markings on the bottom confirm it's a version 5 (it has the class 2 logo) :) - but the box is an older one (it has color service logos) 🤨 -...

Is the TV the source of the signal, or is the source another device connected to the TV? If the TV is the source (as in digital or analog TV tuner), maybe you can disconnect the Amp from HDMI ARC port, increase the volume on the TV, and then reconnect the Amp, and see if there's an increase in...

If the apple TV remote has volume control, and the apple TV handles HDMI CEC, HDMI CEC and ARC are enabled on your TV, it should all be controllable with only the apple TV remote - turning on the apple TV should turn on the TV, set it on the correct hdmi input, turn on the wiim amp and set it...

It can do white, and the other colors don't look like "simple" LEDs, so I think it's an RGB LED, and if I were a bit less lazy, I'd open a feature request to make it configurable ;p

If the source is a turntable on Line in or a TV via optical or HDMI, then you have to use the Amp's bluetooth out, not your phone. If the source is a streaming service, then the selected codec might differ. Depends on your phone. The led is bright green when the source is a bluetooth device...

To be fair, this one was actually only a software issue (CPU not entering sleep state), and was fixed by a software update

I think Wiim is still a young company, and probably smaller than its competition. This product is also their first integrated amp, and fifth product in total. So holding them up to the same standards as companies that have been in business for decades, have 10 times the workforce and sell...

uboot is the bootloader, the timestamp probably only represents when the binary was build from source code it probably does not matter and might never get updated, as any power shortage or bug happening during the bootloader update has a great risk of bricking the device

Yes, my amp is connected to the gateway provided by my internet service provider via an ethernet cable, and my smartphone is associated to the wifi network provided by the same gateway, I didn't have to do anything else to set up the amp, I don't think my phone ever connected to an ad-hoc or...

I had the same issue with regular banana plugs on the speakers end, I had to push really hard on the first insertion. Maybe BFA plugs are less rigid and easier to insert. For the Amp, I got this kind, and didn't have issues: https://ae01.alicdn.com/kf/S4a0fd108ffb24975a66ac165940bb309y.jpg The...

I don't think pcb version necessary relates to the coil whine fix, it might as well be fixed by changing faulty components (with others using the same footprint), or improving the manufacturing process, while keeping the same PCB. Mine it also from 2350 (december 11 to 17) and it's around the...

This is actually the firmware build date. I believe the amp build date can be deduced from the serial number (on the sticker on the bottom of the amp and the side of the box). Mine starts with "P1TF2350" followed by 5 more digits and I think it means it was manufactured during week 50 of 2023...
