I read here on the forum that the card works with Ventura OS - but what could be? I've been scratching my head for a week, I've re-read the entire Internet - there is no money for a new card, but I don't want to buy cheap ones

3 min and i will give answer

nothing
Total Mix is openning but there is no mixer
Rme settings is not opened
No host still red light

With my Fireface400 on a Mac mini M1 and Ventura it matters in which order I power / boot the units. Fireface has to be already on before starting up the Mac.

... sometimes! Just now it went also the other way round.

Hi
I just went thru the whole thread again because it was marked as new replied.
I have the following questions and ideas:
- you say 'it stopped working'. So it worked before? What happened? System update? Bought new Mac? Waedi already asked that, but there was no answer from your side.
- do you have original Apple adapters (FW-TB2 / TB2/TB3)? Gianste probably can confirm this is really important (we were on FB discussing this). Third party adapters often don’t work.
- the RME apps (Fireface settings and Totalmix) are there but won’t open or don’t show a mixer window. The Fireface itself shows a red host led. To me are these clear indicators for a communication issue. So I would suggest to connect another FireWire device to the adapters to check this out (you already swapped cables, so this is checked out)
- don’t forget the simple things: unplug the adapters from the MacBook and from each other, plug them new, maybe to another TB port. Check if everything is firm.

Cool! Yes, sometimes such an issue it's simply caused by broken hardware.

Hello my friends
No problem - you helped me, I will try my best to help you. I am from Russia, exactly from the one with which no one wants to interact now - and this is a big problem. I found a link on the official website of the RME dealer here in Moscow, contacted them. I went to their workshop, they said that the fire wire board most likely burned out and they changed it. However, the card did not work, then they rang the whole circuit and found that a certain device called a stabilizer, or something else, did not work ... In general, the small chip was not working - they replaced it, and everything worked right away. I paid about 80 euros for the repair, and just gave them another 50 euros, because they are great and helped me a lot - and very quickly - it all took 2 hours. How so friends
