Hi all, After a recent update bumped the current kernel to the 6.18 series, the rear 3.5mm jack on my NanoPC-T6 LTS stopped playing any sound. I'm connecting it to an external amplifier that worked fine before the update. What I see on 6.18 (6.18.35-current-rockchip64): The audio card (rt5616) still shows up in aplay -l and playback commands run without errors, but no sound comes out. Volume levels and mute aren't the issue — I checked those. What fixed it: downgrading via armbian-config to linux-image-current-rockchip64=25.11.2 (kernel 6.12.58). With 6.12 the audio works perfectly again. So 6.12 works and 6.18 doesn't, at least on my board. Is anyone else seeing this on a T6 / T6 LTS with the 6.18 current kernel? Happy to share any logs or run commands if it helps to narrow it down. Thanks!

Thank you for moving my post to the appropriate section. I apologize for posting in the wrong area initially. To reiterate my question for this General forum: I have a Skyworth TV box with a Realtek RTD1325. I am looking for any guidance on whether it is possible to run Armbian on this hardware, even experimentally. Has anyone here worked with similar Realtek-based devices, or could someone point me toward resources for building a custom image for the RTD13xx family? I understand this is outside the usual supported hardware, but any advice would be greatly appreciated. Thank you.

Hi SymbiosisSystems, Same problem like you with kernel 6.18.35 and 6.18.37, all it's Okok with 6.18.10 like I said in this post:
