I have an Arylic BP50 preamplifier at home, which is a very fine device, but I was annoyed that the sound would occasionally cut out. Sometimes in the middle of a song, but especially frequently when I switched to a new track in Spotify or Amazon Music. While the problem was initially resolved by a power cycle, it was still annoying. I tried several updates provided by Arylic to solve the problem, but unfortunately, the issue didn’t improve. On the contrary, new problems arose, such as poor sound after powering on, which then improved over time. But mind you, the interruptions were still there.
Then I had an idea: I rolled back to the latest stable firmware version 51-ba37596b-8 and used the optical output signal. Of course, I needed the RCA-based signal to connect the rest of my audio chain, so I got this little DAC called Taishan from Fiio, and voilà. No more audio cutouts and the sound quality is outstanding. Yay!
To solve the ARC connection issue, I bought a new HDMI cable from Silkland on Amazon and since then, it’s been working reliably and stably. Apparently the cable length also plays a role, which is why I used a cable that is only two meters long.
Perhaps these tips will help others, too; I’d be very happy if they did…
I remain grateful to Arylic for the devices they bring to market and would be delighted if the issues mentioned were resolved. Again, there must be a reason why the sound occasionally interrupts with the RCA output. And especially why this doesn’t seem to be the case with the optical output. The new firmware beginning from 52-xxxxxxx should be revised in this respect…
Hi Tobias, thanks for your feedback and also advice. Appreciate for the kindness. We’ll try to improve and see if could release a new firmware release.
Btw, I have no idea for the sound cut out on RCA output. Sure, literally I can understand, but I never saw this on my device or in testing. Could you please record a small clip, so I can understand it better.
“The enable function is used to reduce power consumption while the device is not in use. When a logic low is applied to this pin, the overall circuits are turned off. Line driver output and PVSS are pulled to ground. When a logic high is applied to enable pin, the PVSS is started to build-up and line driver output signal is released after about 0.5ms typically.”
Maybe you can have a look at how this driver responds to incoming audio signals which sometimes might enable this specific protection pin cutting the audio signal…
Another idea: The audio dropouts mostly occur when I change songs, then in pauses and in very quiet tracks. Is it possible that the under voltage protection of this chip kicks in and mutes it?
I too am encountering this problem with the BP-50. It has been a problem since I got the BP50 in January 2024. I’ve tested each firmware update that was released since then, and the audio dropout issue still happens the same across every firmware.
The same problem occurs testing on two separate HDTVs (VIZIO, Inc M601d-A3, and LG Electronics LG TV SSCR2) both with HDMI ARC output to the BP50.
It’s currently running firmware: ARYLIC_BP50-0057-d94126e9-20240918.MVA
The audio output from the BP50 is using RCA line out. The problem only happens when using HDMI ARC input. RCA line-in from seems to work fine and does not have audio drop-outs.
When the audio drop-out occurs:
The BP50 is still “ON” and the “STANDBY” light is NOT lit up
No audio can be heard from the BP50’s RCA output
A hard power cycle with the physical ON/OFF switch or IR remote power button resets the BP50 and it begins working again until the next time something triggers an audio drop-out again
Usually I have noticed that the audio drop-outs are more likely to occur when watching a YouTube video source that has a very short period of audio silence. (Maybe a glitch, or maybe could be the AD22650 issue Tobias mentions above?)

Hello, that sounds exactly like my problem. In my opinion, the problem isn’t with the input signal, but solely with the line output. Maybe you could try my solution and use the Toslink output. Get yourself a small DAC adapter (I use the Taishan from Fiio) and connect it between the RCA out and the RCA cable. A small adapter like this doesn’t cost much and might solve your problem relatively easily…
