You could long press the ARC button on remote to turn OFF/ON the auto standby feature.
Besides, long press the PHONO button on remote, could switch between MM/MC mode. Btw, normally, it works in MM mode, and when switch to MC mode, the device will just apply a +10dB extra gain over the phono input.
To upgrade B50 model:
You need a USB disk with format FAT (not FAT32 or exFAT for now).
And copy the firmware MVA file into the disk root directory (note: you need to delete any other MVA files), then plug the disk into B50,
And then double press the front knob quickly (double click).
If all goes well, all LEDs of B50 will light up which indicates the upgrading begins. And will turn to normal when finished. Please do make sure don’t cut power in this process, or it will brick the device.
Same issue here. I bought the B50 to replace a Denon AVR-S540BT. I’ve used it for 3 years and never once had an issue with ARC or CEC, but with the B50 there is about a 50% chance I’ll get audio
My issue seems different to yours, so I’ll post it here just incase anyone has a similar issue. Its a Sony XBR-55X850D and when I turn it on, it will display “Switching to TV speakers” and then “Switching to External Audio”, but for whatever reason, most of the time there is then no sound through the B50. I have to switch back to internal speakers via the menu and back to external, which most of the time fixes it.
Testing turning the B50 on first seems to fix the issue, but that doesn’t really seem like a solution to me, as I want a single remote experience.
Tried updating the firmware above, but 3 different flash drives formatted to FAT32 with file on don’t seem to do anything in the B50. Tried double pressing the knob a bunch of times, different speeds, and it never lights up like described
I think we need more detailed instructions… I formatted a USB to MBR/FAT32 and copied the file as without any renaming, then I plugged the usb into the USB type A port in the back, when I do the device switches to “USB”, then I double press the volume button, and nothing happens.
What am I doing wrong if anything? Current firmware on the B50 is 48-b0ab8739-7 according to Go Control.
I was using a 32GB usb stick, and I tried both FAT12 and FAT16, neither worked.
What did work is I had a really old 1GB USB stick lying around, and when I used that, it worked immediately. I also formatted/partitioned the 1GB stick to MBR/FAT16.
This seems to indicate the device is very sensitive to what USB stick you’re using, so field upgrades via USB is not really feasible unless Arylic can provide a list of tested USB sticks.
That caveat aside, ARC output on the TV seems reliable after the update, and disabling ARC CEC standby seems to persist across power cycles on the B50, so I’ll be keeping the device personally, but find it still difficult to recommend to anyone without big asterisks on the recommendation due to the USB support problem with upgrades.
I believe what you’re saying, but I think it just points to the need to publish some sort of compatibility list or known good list. Even better would be if the update can be just done through the app without a USB stick.
I worry about the “if all goes well” part when updating firmware What if it doesn’t go well? I hope I haven’t bricked the amp? And where do I find the latest firmware?
Then the question is, where do I download new firmware for the B50? There may not be any but how and where do I check for upgrades? I have been checking around the ste but can’t find anything about B50 firmware.
yes, we did not officially release firmware yet. And one possible solution: user would be notified on App that there’s a new version, and then will guide user for the steps for the upgrading, or he could choose to ignore it anyway.
It’s not good experience for user to upgrade device in this way, but we did not find a way to transfer firmware with considerable time via BLE to device. So, this is the idea.
I have a situation a bit different but related with ARC. In fact after some standby / on tests from my TV (TCL - Android) and one time B50 resumed ARC but no sound - even with volume in max and also switching between fonts (moved to line in and then to ARC) . After did standby / on it come back normally.
About the situation I mentioned: its a bit annoying - maybe is a TV issue - but when I do standby, TV returns to built-in speakers with volume 100 for a second and its really annoying. I can change built-in speakers volume to 20 or 10, but next time (when I do standby - turn on from TV), volume resumes always to 100. I think it happens also when turn on TV - built-in speakers with 100 - but since its Android and I use IPTV app, this is not perceived before audio streaming really starts.
Tried updating from 48, amp sees the update on usb and prompts update. Amp appears to start update with all LEDs on and power cycle however FW displayed in app never actually updates.
Updated firmware via the official rollout (B50 Firmware Version Update 52-452f344c) and also updated the app, all went smoothly. There is an option to turn off ARC standby in the app. I have turned that off, we’ll see if it fixed the issue.
EDIT: after a quick test it appears to be working after having ARC standby turned off
Having this exact issue on my BP50 via ARC. Noticeable crackling and dropped audio. Hopefully fixed in a firmware update. I’d love for the firmware versions to be available on the website as well. Cheers!
I also have a BP50 and can confirm I’m seeing the same issue. TV is a Vizio M601d-A3R, and supports CEC. I have tested it separately with a Pulse-Eight CEC adapter and it works well to turn TV on and off. The Vizio TV has a menu under “System → CEC → Device Discovery” which detects the BP50 when CEC devices are scanned.
Tried the long-press using the BP50 remote ARC button to disable standby mode, but this appears to not work either. The BP50 still goes into standby when the TV turns off, and does not turn on when TV is turned back on. Also tried checking the “ARC standby” switch was off in the GoControl app (toggled it again and retested just to be sure). Same result each time no matter the setting.
My BP50 is running this firmware version from the factory: 52-8456a6b7-8 (as shown in GoControl app)
I’ve updated the BP50 firmware to the latest version released today: 56-0bf6cc3e-8
Firmware update was successful, and this new version is listed in the iOS GoControl app when connecting to the device.
However, unfortunately the update has not solved the issues with HDMI ARC (details here).
What if it doesn’t go well? I hope I haven’t bricked the amp? And where do I find the latest firmware?
