Hi Raptor, I managed to get the information I was looking for, I joined a forum called LinuxMusicians, in which I found a very nice user who gave me all the information I needed. He told me that the RME HDSPe AIO works well under Linux and that even if it costs a bit, I won't regret it. He told me that Alsa support started years ago, support has been present in the kernel for years now. I had Alsa-Tools installed which I found in a version 1.2.2.1 and then the Alsa firmware dedicated to RME cards. Now I should be ready to use this Sound Card, I just ordered it and I hope it arrives in normal times given the emergency COVID-19 ... Thanks for the information, I will write on the forum to give news of how it goes this beautiful sound card. See you soon and hold on that the Power community needs you in the first place! We must overcome the crisis! If there is something we can do to help you don't exist to ask, the Power community is all with you!
