Yep, been there.
They did the pooch with the first driver version that had new Cue Mix console.
Looked nice and all, but with my Ultralite it went all goofy when you changed tracks to stereo and whatnot.
I went back to 18.104.22.168 but now I’m using 22.214.171.124 and it seems to work okay.
,but the backlight problem uuummmm ,long story cut short ,my ultralite hybrid is a trade in with motu as my 828 mkII backlight started playing up and then getting digital spillage from the s/pdif which caused loads of noise and crackling with the led lights going mad until one day the bugger would not turn on , it was only 3 years old ,sent it to motu and 4 1/2 months later they decided to do a deal on the ultralite for £100 ,believe me i was not happy with motu. so i hope what yours is doing is not the start of a great hair pulling out session like the 828 !
all said i must amit i do like the ultralite more than the 828 and will carry on using motu like i have since the atari days. all my thoughts go with you in your dark hours of motu madness !
Sadly, I’ve read a few stories like yours with the 828’s.
I first noticed my backlight acting weird about a year and a half ago…it was only 3 years old as well.
At first I had kittens and thought it was the beginning of the end.
Same with the glitchies…first time it happened I near had a heart attack because I thought a eardrum blowing pop or screech was about to blast out my monitors.
Fortunately, over the years it’s never popped but only put the signal through a digital mangler until I cycled the unit.
I’ve long learned to live with both issues, because audiowise it still sounds good and works the same as when I got it. I just look at it as being haunted instead of broken.
Although I think I’ll be going RME next time though.
